The unit is designed for operation in an industrial environment and must not be used in a household environment or similar.
Main task of SPP-N118 is measurement of instantaneous flow (flow rate), and counting of
total flow (e.g. passage of fluid or gas ), The device can be used as regulator, to control industrial process. Measurement of instantaneous flow can be indicated in range: 0 to 9999
(plus decimal point) and can be expressed in any scalable user units of flow and three time measures (second, minute, hour). Total flow can be indicated in range from 0.000 to
4294967295 user units with maximum resolution of 0.00001 units.
SPP-N118 can cooperate with flow sensors with current output (0-20mA or 4-20mA).
Sensors can be powered from sensor supply output (stabilized, 24VDC +5%, -10% 100mA).
The device is equipped in 1 or 2 relay outputs or OC-type outputs, which can be driven
due to instantaneous flow, total flow or batcher counter value. Optionally SPP-N118 with one
relay output (or OC-type output) can be equipped with active current output, passive isolated current output or active voltage output. Build in RS 485 interface enables access to all internal registers, and supports MODBUS RTU communication protocol. The controller can be ordered in two power supply versions.
The device has 5 buttons being used for main presets programming. To get high protection level, the keyboard is mounted under transparent cover. To allow user to change presets without opening the cover, an IR sensor is mounted. Remote controller contains basic
functions to handle menu of the device (note, that remote controller is not a part of the SPP-
N118 set – it is an additional equipment).
Additional features:
• alarm preset; alarm signal is released when measurement exceeds measurement range
• direct access to relays thresholds settings, without password,
• batcher mode.

Caution
!
- Installation should be conducted by qualified personnel . During installation all available safety requirements should be considered. The fitter is responsible for executing the installation according to this manual, local safety and EMC regulations.
- The unit is not equipped with an internal fuse or power supply circuit breaker.
Because of this an external time-delay cut-out fuse with minimal possible nominal current value must be used (recommended bipolar, max. 2A) and a power supply circuit-breaker located near the unit. In the case of using a monopolar fuse it must be mounted on the phase cable (L).
- The power supply network cable diameter must be selected in such a way that in the case of a short circuit of the cable from the side of the unit the cable shall be protected against destruction with an electrical installation fuse.
- Wiring must meet appropriate standards and local regulations and laws.
User manual - FLOW METER SPP-N118
!
- In order to secure against accidental short circuit the connection cables must be terminated with appropriate insulated cable tips.
- Tighten the clamping screws. The recommended tightening torque is 0.5 Nm.
Loose screws can cause fire or defective operation. Over tightening can lead to damaging the connections inside the units and breaking the thread.
- In the case of the unit being fitted with separable clamps they should be inserted into appropriate connectors in the unit, even if they are not used for any connections.
- Unused clamps (marked as n.c.) must not be used for connecting any connecting cables (e.g. as bridges), because this can cause damage to the equipment or electric shock.
- If the unit is equipped with housing, covers and sealing packing, protecting against water intrusion, pay special attention to their correct tightening or clamping.
In the case of any doubt consider using additional preventive measures (covers, roofing, seals, etc.). Carelessly executed assembly can increase the risk of electric shock.
- After the installation is completed do not touch the unit’s connections when it is switched on, because it carries the risk of electrical shock.
Due to possible significant interference in industrial installations appropriate measures assuring correct operation of the unit must be applied. To avoid the unit of improper indications keep recommendations listed below.
–
Avoid common (parallel) leading of signal cables and transmission cables together with power supply cables and cables controlling induction loads (e.g. contactors). Such cables should cross at a right angle.
–
Contactor coils and induction loads should be equipped with anti-interference protection systems, e.g. RC-type.
–
Use of screened signal cables is recommended. Signal cable screens should be connected to the earthing only at one of the ends of the screened cable.
–
In the case of magnetically induced interference the use of twisted couples of signal cables (so-called “spirals”) is recommended. The spiral (best if shielded) must be used with RS-485 serial transmission connections.
–
In the case of measurement or control signals are longer than 30m or go outside of the building then additional safety circuits are required.
–
In the case of interference from the power supply side the use of appropriate antiinterference filters is recommended. Bear in mind that the connection between the filter and the unit should be as short as possible and the metal housing of the filter must be connected to the earthing with largest possible surface. The cables connected to the filter output must not run in parallel with cables with interference (e.g. circuits controlling relays or contactors).

Figure 4.12. Connection of power supply and relays
Contacts of relay outputs are not equipped with spark suppressors. While use the relay outputs for switching of inductive loads (coils, contactors, power relays, electromagnets, motors etc.) it is required to use additional suppression circuit (typically capacitor 47nF/ min. 250VAC in series with
100R/5W resistor), connected in parallel to relay terminals or (better) directly on the load. In consequence of using the suppression circuit, the level of generated electromagnetic disturbances is lower, and the life of relay contacts rises.

After turning the power supply on, device ID and software version are showed on the display, next the controller goes to the measurement mode.
6.1. MEASUREMENT MODE
In the measure mode, device displays instantaneous measurement (flow value or time per one unit of flow, depending on „F or P” parameter value) equivalent to input current, total flow or batcher counter value.
Displayed value presentation is defined by parameters “F unit”, “t unit” and “b unit” with resolution defined by parameters “F PrEc”, “t PrEc” and “b PrEc”.
... 879 876 543 . 219
“F unit” “F PrEc”

Instantaneous flow (flow rate) is displayed in units defined by parameter “F unit” and
“Ftunit” (min., sec. or h), with resolution defined by “
Point
” (max. 3 digits after decimal point). Device converts measured current to selected units accordingly to conversion characteristic selected by user. The measurement range equal to the nominal range is called:
nominal measurement range, and the measurement range equal to the extended nominal
range is called: permissible measurement range (Figure 6.1, 6.2).

– If input current range is strongly overloaded, device can display improper results
– While time per one unit of flow is displayed (parameter “F or P” = “PEriod”):
• If flow value equals 0, then message “-STOP-” is displayed.
• If value of period is too high to be fitted on 6 digits, message “-OvLd-”
(Overload) is displayed instead of the result.
• If flow value is different than 0 but value of period is too small to be fitted on 6 digits, message “-UnLd-” (Underload) is displayed instead of the result.
Total flow is displayed in units defined by parameter “t unit” with resolution defined by parameter “t PrEc” (max 3 digits after decimal point). If total flow counter overflows, warning
“tot ov” is displayed alternatively with maximum counter value. Total flow counter can be
zeroed using “Clrtot” option of “totAL” submenu, using [
S ] button (press and hold by at
least 2 sec.), electrically via programmable input or via RS-485 interface by writing of value
0000h to any of total flow counter result registers.
i
S ] button can be activated using „m CLr” option of “totAL” submenu.
Zeroing via programmable input can be activated using „Func” option of “Pr inP” submenu.
Parameter “CutoFF”, allows to define input current value, below which total amount of flow is not counted (incremented).
i
If “CutoFF” is set to value different than zero and if input current is lower than this value, then instantaneous flow (flow rate) is displayed, but TOTAL
COUNTER IS NOT INCREMENTED.

while total flow is displayed. If batcher counter is displayed then “
S” LED is pulsing.
i
Batching counter can be displayed while batcher mode only (set „SourCE”=”bAt” in
„rELAy1” submenu).
Functions of [^] and [v] buttons depend on kind of presently displayed value:
• If instantaneous flow (flow rate) is displayed ( LED marked “
S” is off) or batcher counter value (“
S” LED is pulsing), user can check main threshold values and
number of batches counter
(which indicates how many times batcher was started). After pressing [^] or [v] buttons, name of the threshold (e.g. ”rELPr1”) and its value or ”bAtCnt” label and
number of batches counter
will be displayed on the display in alternating mode.
If [^] or [v] will be pressed in 5 sec again, the next threshold will be displayed, else the device comes back to the measurement mode. If a free access is enabled (see description of ”SECu” menu), user can change the value of particular threshold pressing button
[ENTER] (see: PARAMETERS EDITION). Using [
number of batches counter
is displayed and confirm „CLEAr?” message by [ENTER] button causes zeroing
number of batches counter
.
i
• If particular parameter has been changed and confirmed in quick view mode, its new value is displayed in alternating mode with parameter name by few seconds. Confirmed changes may be checked or user can switch viewed parameter pressing [^] or [v] button.
• Number of batches counter is incremented after each start of batching process
(every first start after batcher counter zeroing).
• If batcher counter value is displayed (“
S” LED is pulsing) and counter value exceeds 6 digits, then decimal point of the most left digit is pulsing. To view most significant digits, it is required to decrease resolution or/and change unit..
• If total flow counter value is displayed ( LED marked “
S” is on), and its length exceeds 6 digits, buttons [^] and [v] enable switching between more and less significant digits.
Positions of currently displayed digits are signalized by flashing decimal points (see example below).

Counting of pulses and controlling or relays is realised regardless of operation mode
(after entering to menu mode counting and controlling is continued in “background”.
6.2. DETECTION OF THE PEAK VALUES
The SPP-N118 flow meter is equipped with peaks detection function. It can detect a
peaks of the input signal and display their values. Presets connected with this function are placed in ”HOLd” menu (see description of ”HOLd” menu). The detection of the peak can be done if the measured signal raises and drops of value at least equal to parameter ”PEA”.
Detected peaks are displayed during the time defined by parameter ”timE”. If a new peak will be detected while one is displayed, this new peak will be displayed and display time counter
will be cleared (Figure 6.4). If no peaks are detected while time ”timE” elapses, device starts
to show the current value of input signal again. If „HdiS”=”HOLD” then setting parameter
"timE"=0.0 causes holding peak value until [ESC] button is pressed. If „HdiS”=”rEAL” then value "timE"=0.0 means no holding. Displaying peak value is signalized by flashing most right decimal point.
The relays/LEDs and the analogue output can be controlled depend on the current value of input signal or the peak value (see ”HOLd” menu).

6.3. CONTROL OF THE RELAY OUTPUTS
The control of the object (measured signal) is done due to instantaneous flow value
(current flow rate), total flow counter value or batcher counter value , and is realized via relay outputs. Front panel LEDs named „R” indicates the state of particular relay output.
i
If device is not equipped with one or more relay outputs, menus refer to this relays are available, but apply to LED indicators only. In such case LEDs indicates exceeding of particular thresholds.
Modes of the control can be changed depend on the values of parameters “SourCE”,
“SEt P”, “SEt P2”, “HYSt ”, “modE”, “t on”, “t oFF”, “unit” and “ALArmS” (available in
”rELAy1” ÷ ”rELAy2” menu). If relay is controlled due to total flow counter value
(“SourCE” = ”tot”), additional parameters are available in menu. Parameters “t PrEC” and
“t unit” defining the unit and resolution of displayed thresholds and hysteresis of selected relay. If relay is controlled due to batcher counter value (“SourCE” = ”bAt”), in addition
“b PrEC”, “b coEF” and “b unit” parameters are available in menu but parameters:
“SEt P2”, “HYSt ”, “modE”, “t on”, “t oFF”, “unit” are unavailable. Parameters “b PrEC” and “b unit” define the resolution and unit of displayed thresholds and hysteresis of selected relay. Depend on “modE” parameter, relays can be not used or controlled over one or two thresholds values.
If one threshold is used (Figure 6.5) the relay can be turned on (“modE” = ”on”) or off
(“modE” = ”oFF”) when the input signal value is contained in zone A. If two thresholds are
used (Figure 6.6) the relay will be turned on when value of input signal is contained in zone A
(“modE” = ”in”) or zone B (“modE” = ”out”) and turned off if the signal is contained in the second one.

Figure 6.8. Principle of LED/relay output operation for two thresholds mode
26
User manual - FLOW METER SPP-N118
Figure 6.8 presents the principle of relay outputs operation for two thresholds mode, and
an example values of other parameters. In this mode parameter “SEt P2” is accessible in common with “SEt P2”, this parameter describes a second threshold of the relay output. The parameters “HYSt”, “modE”, “t on”, “t oFF”, “unit” and “ALArmS” are connected with both
“SEt P” and “SEt P2” thresholds. While the controlling process, the relay output changes its state depends of both “SEt P” and “SEt P2” thresholds in similar way as it was described in one threshold mode.
If two threshold mode is used, “modE” parameter defines state of the relay output when the input value occurs in a particular zone defined by border values of both thresholds. The relay can be turned on if the input value is contained in zone A (“modE” = ”in”) or zone B
(“modE” = ”out”) and turned off if it is contained in the second one (Figure 6.8).
i
The sequence of thresholds “SEt P” and “SEt P2” can be set in any order, due to the control of relay outputs is done depend on difference between thresholds values
(zone A ) and outside of threshold values (zone B).
6.3.3. Batcher mode and „PrE r1” mode
To switch the device into a batcher mode in submenu „rELay1” user should set
„SourCE”=„bAt”. There are following parameters related to R1 in this mode: “SourCE”,
“SEt P”, “b PrEC”, “b unit” and “ALArmS”. Parameters “SEt P”, “b PrEC”, “b unit” define quantity of batched medium, displaying precision and the unit respectively. Parameter
“ALArmS” allows to set behaviour of relay output in critical situations.
Pressing [ENTER] button while device is in batcher mode causes start of batching and set of relay R1. Successive pressings of [ENTER] button cause pause/restart of batching and switching R1 relay off/on. When batcher counter reaches value equal to “SEt P” then relay
R1 is switched off.
i
If batcher counter is overloaded then its maximal value is displayed alternatively with “bAt ov” message. Overload of this counter do not change state of relays.
To start another pouring cycle, batcher counter must be cleared and next new cycle initiated by pressing [ENTER] button. Batcher counter can be zeroed using “CLrbAt” option of
S ] button (press and hold by at least 2 sec.), electrically via
programmable input or via RS-485 interface by writing of value 0000h to any of batcher counter result registers. After zeroing of batcher counter, currently realized pouring is stopped and relays switched off.
i
Zeroing electrically via programmable input causes start of the next batching automatically. In other cases to start of the next batching it is required to use
[ENTER] button or write of value 0001h to any of batcher counter result registers using RS-485 interface. To stop batching it is required to use [ENTER] button or write of value 0002h to any of batcher counter result registers using RS-485 interface.
Due to delays while closing/opening the valves decreasing of “SEt P” parameter
(defining volume of batched medium) can be necessary. Fact that zeroing of the batcher
S ] stops the batching process and switches off the relays can be used for
calculating desired value of “SEt P”. Note, that if relay which is controlled by batcher counter is used for driving the valve, then value counted after zeroing of the batcher counter tells how much of medium flows through valve during closing.
27
User manual - FLOW METER SPP-N118
Number of batches is counted by another counter (number of batches counter) and stored into the non-volatile memory. To display the value of this counter use [^] or [v] button.
After that message ”bAtCnt” and content of number of batches counter are displayed
alternatively. To clear this counter press [
S ] button while device displays it and confirm by
pressing [ETNER] button. Every initialisation of batcher (start of batching) causes incrementation of number of batches counter.
If parameter „SourCE” of relay (other than R1) is set to „PrE r1” then parameters
„SEt P” and „SEt P2” of particular relay means control advance of this relay in relation to threshold of relay R1 („SEt P” parameter in „rELAy1” submenu). In other words, first threshold of relay R2 equals
SEt P
R1
−
SEt P
R2
and value of its second threshold equals
SEt P
R1
−
SEt P2
R2
. Thresholds of other relays (if available) are calculated in the same way.
Relays working in this mode can be used to control additional valve of the batcher.
i
If relay other than R1 should change its state at the end of batching (simultaneously at turning relay R1 off), it is required to set „modE”=”in” or ”out” and set zero value for one of its thresholds („SEt P” or „SEt P2”).
The clearing and starting of next batching can be run automatically, with defined delay between successive doses. To enable this feature it is necessary to set parameters: „A rES”
(autoreset function), „A dLy” and „Atunit” (desired delay and unit of time) of “bAtCH” menu.
6.3.4. Use of the batcher counter as a marker
This feature allows to use the batcher counter for cyclic control of relays (except R1) by volume of flowing medium (e.g. switching relay on after counter reaches 9 litres and switch it off after counter reaches -10 litres, in other words generate one pulse every 10 litres. For example to use R2 as marker it is required to set counter as follow:
1.
Set relay R1 to batcher mode („SourCE”=”bAt”).
2.
Set „SEt P” of relay R1 to desired cyclic volume (e.g. 10 litres). This value defines cycle duration expressed in units of flow (not a time) because cycle time depends on flow speed.
3.
Set relay R2 as batcher pre-trig (“SourCE”=“PrE R1”).
4.
Set “modE” of R2 according to desired mode of operation (in this example “modE”
= “on”, however it can be also set to other modes). Depending on this parametrer, relay will be no or off in desired phase of the cycle.
5.
Set “
SEt P
” (and “
SEt P2
” if “modE” = “in” or “modE” =“out”) of relay R2 according to desired phase within it should be on (and off). These values must be lower than threshold of R1. Note, that time of active state of R2 depends on flow speed. It is recommended to set “
SEt P
” of R2 to half of R1 threshold but it is not necessary (in this example set “1”, what causes that R2 will be activated when batcher counter reaches 9 litres ).
6.
Switch on autoreset of batcher counter
(„A rES”=„on”) and set „A dLy” to 0.
Note that R1 is switched off for a short period every time batcher counter is cleared, what can be used to any purpose.

“SourCE”
“Flo”
“bAt”
“tot”
- parameter defining kind of result using to control state of this relay.
It can be set to one of three values:
- relay is controlled due to current flow rate value or stored peak of flow rate
(see “Hold” menu),
- relay is controlled due to batcher counter value,
- relay is controlled due to total counter result.
i
“bAt” option is available for relay R1 only. For the rest of relays „PrE r1” option is available. „PrE r1” option means controlling in relation to „SEt P” of relay R1 (see
CONTROL OF THE RELAY OUTPUTS).
“SEt P”
- first threshold of the relay (range 0 ÷ 999999). Threshold is the medium value of
relay hysteresis. While batcher mode („SourCE”=„bAt”) „SEt P” value means the quantity of pouring matter.
“SEt P2” - second threshold of the relay (range 0 ÷ 999999). This threshold is accessible when ”modE” parameter is set to „in” or „out” value. Threshold is the medium
value of relay hysteresis.
“HYSt” - hysteresis of relay (range 0 ÷ 99999). Full hysteresis of the relay is equal to 2x
“HYSt” parameter. The relay state can change when an input signal is out of
threshold-hysteresis to threshold+hysteresis zone.
i
Presented parameters should be set to ensure that ”SEt P” + ”HYSt”,
”SEt P2” + ”HYSt”, ”SEt P” - ”HYSt” or ”SEt P2” - ”HYSt” do not exceeds the measure range. Additionally, in two threshold mode (“modE”= „in” or „out”), the hysteresis for both thresholds must not cover each other (in other case relay can't change its state).
“b PrEc” - decimal point position (displaying precision of the relay thresholds ) when relay is controlled due to batcher counter result. It can be set to:
“ 0“
“ 0.0“

Parameters ”b PrEc” and ”b unit” are available only for relay R1 while batcher mode (“SourCE” = ”bAt”) is set. When current flow rate is used to control relays, the unit and precision of the thresholds and hysteresis are defined by parameters
“F unit”, “Ftunit” and “F PrEc” of menu ”Flouu”. When relay (other than R1) is controlled in relation to „SEt P” threshold of relay R1 (“SourCE” = ”PrE r1”), the unit and precision of the thresholds and hysteresis of relay (other than R1) are defined by parameters „b unit” and „b PrEC” parameters available in submenu of relay R1.
“t PrEc” - decimal point position (displaying precision of the relay thresholds ) when relay is controlled due to total flow counter result. It can be set to:
“ 0“

i
Parameters ”t PrEc” and ”t unit” are available only if total flow counter is used to control relay output (“SourCE” = ”tot”). When current flow rate is used to control relays, the unit and precision of the thresholds and hysteresis are defined by parameters “F unit”, “Ftunit” and “F PrEc” of menu ”Flouu”. When relay (other than R1) is controlled in relation to „SEt P” threshold of relay R1
(“SourCE” = ”PrE r1”), the unit and precision of the thresholds and hysteresis of relay (other than R1) are defined by parameters „b unit” and „b PrEC” parameters available in submenu of relay R1.
“modE” - relay operation mode:
“noACt” - the relay is not active (permanent turned off)
“on”
- one threshold mode, the relay is turned ON when input signal exceeds
SEt P + HYSt value, and is turned off back when the input signal became lower than SEt P - HYSt,
“oFF” - one threshold mode, the relay is turned OFF when input signal exceeds
SEt P + HYSt value, and is turned on back when the input signal became lower than SEt P - HYSt,
“in”
- two threshold mode, the relay is turned ON when the input signal is bigger than “lower threshold + HYSt” and lower than “bigger
threshold - HYSt”, and turned off when the input signal is contained in the second zone. The bigger threshold means bigger one of “SEt P” and “SEt P2” thresholds, the lower threshold” means lower one of
“SEt P” and “SEt P2” thresholds.

“I tyPE“ - type of the input / sensor. This parameter can be set to values:
”0-20”, “4-20”
- current inputs of 0÷20mA or 4÷20mA of measurement range respectively. Displayed values are defined by parameters
“Lo CAL”,”Hi CAL” (or by user defined characteristic points) and parameter ”Point”.
“I CHAr“ - this option sets type of the conversion characteristic.
This preset is essential when meter cooperates with flow sensor, which changes it's output current accordingly to characteristic other than linear. It can be set to:
”LinEAr” - linear
“Square” - square
“Sqroot” - square root
When one of those characteristics is chosen display range is defined by “Lo CAL” and “Hi CAL”.
“USEr”
User defined characteristic. Maximal length 20 points. Every point is defined by user. Adding, Editing and Deleting of points is done by options
„AddPnt”, „EdtPnt”, „dELPnt” („FLouu” menu) respectively.
i
If user defined characteristic is selected, and if number of defined points is lower than 2 then warning ”Errc” is displayed in measurement mode.
The process of displayed result calculation is described in details in DISPLAY VALUES
CALCULATION paragraph.
“Point“
- decimal point position (precision of flow rate displaying). It can be set to:
“ 0“
“ 0.0“
“ 0.00“
“0.000“

“F unit” - the unit of volume used for flow rate displaying . It can be set to: (”unit.“ - units, or “1000un” - thousands of units). Units expressed by “F unit” are conventional, and can be exchanged to any other pair of units e.g. for powders it can be kilogram and tonne, for liquids it can be litre or cubic meter.
“Ftunit” - time unit used for flow rate displaying .It can be set to:
(”SEC“ - seconds, ”min” - minutes or “hour” - hours).
i
The unit used to displaying the flow rate, depends simultaneously on parameters:
“F coEF”, “F unit” and “Ftunit”, for example: unit/min or 1000un/h etc.
“F or P” - type of value displayed on the display:
“FL vAL” - flow value,
“PEriod” - time per one unit of flow,
35
User manual - FLOW METER SPP-N118
“Lo CAL”
“Hi CAL”

Available range for these parameters: 0 ÷ 9999.
i
If user defined characteristic is selected (parameter “I CHAr” = ”USEr”) the parameters „Lo CAL” and „Hi CAL” are not available for modification, due to their values are calculated from defined characteristic.
“F coEF” - conversion coefficient. Changes analogue input unit to any unit used to calculate flow by multiplying current flow measurement value (after calculating user characteristics in “I CHAr” parameter) by value in “F coEF” parameter. Firstly, parameter editing requires to enter a value (by entering a digit in each blinking display separately), secondly to select decimal point position (blinking dot on selected position). There are following decimal point position options:
000000. - integer value, no decimal places,
00000.0 - one decimal place,
0000.00 - two decimal places,
000.000 - three decimal places,
00.0000 - four decimal places,
0.00000 - five decimal places,
000000 - six decimal places,
For example: 1 [ l ] = 0,264172 [US gallon], so F coEF = 264172 (no decimal places)
i
Decimal point position in “Piont” and “F coEF” parameters does not affect on each other.
“AddPnt” - this option allow user to add single point to the user defined characteristic.
After selection of this option device waits for „X” and „Y” coordinates of new point.
Modification of the coordinates is done accordingly to numerical parameters edition.
Coordinate „X” defines the percentage ratio of input current to selected current range. The „X” range: -99,9 ÷ 199,9. Coordinate „Y” defines displayed value for particular „X” value. The „Y” value can be changed in range: 0 ÷ 9999, decimal point position depend on „Point” parameter (”FLouu ” menu) .
i
• User can not enter two points with the same value of „ X ” coordinate. If user trays to do it, ”Err” warning is displayed. To modify any defined point use ”EdtPnt” option.
• To distinguish „X” and „Y” coordinates, if „X” coordinate is displayed an additional decimal point on utmost right position is displayed.
• If user defined characteristic is selected, and if number of defined points is lower than 2 then warning ”Errc” is displayed in measurement mode.
36
User manual - FLOW METER SPP-N118
“dELPnt” - this option allows user to delete any of the points of the user defined characteristic. After selection current number of points of the user defined characteristic is displayed for about approx. 1,5 sec. After that device waits for selection of point being deleted (by [^], [v] buttons). The short pressing of [ENTER] button causes by switching between X and Y value of the displayed point. The long press (press and hold at least 2 sec) of [ENTER] button causes by displaying
„dEL?” ask. If [ENTER] button is pressed again, current point is deleted and new updated number of points of the user defined characteristic is displayed.
“EdtPnt” - this option allows user to modify of particular point of the user defined characteristic. After selection current number of points of the user defined characteristic is displayed for about approx. 1,5 sec. After that device waits for selection of point being edited (by [^], [v] buttons). The short pressing of [ENTER] button causes by switching between X and Y value of the displayed point. The long press (press and hold at least 2 sec) of [ENTER] button causes by entering to edit the selected coordinate of the point. Modification of the coordinates is done accordingly to numerical parameters edition.
i
“AddPnt”, ”dELPnt” and “EdtPnt” options are available only if the user defined characteristic is used (it means when parameter “I CHAr” = ”USEr”).
“CutoFF” - this parameter, allows to define input current value, below which total amount of flow is not counted (incremented), but current flow rate is displayed. Parameter
“Cutoff” is expressed as percentage value of input current nominal range (0-20mA or 4-20mA), and can be set in range 0 ÷ 9.9 %,
i
If “CutoFF” is set to value different than zero and if input current is lower than this value, then instantaneous flow (flow rate) is displayed, but TOTAL
COUNTER IS NOT INCREMENTED.
Cutoff Threshold “CT” is defined by formulas below:
CT =
" CutoFF" × 20mA
100
for 0 ÷ 20 mA
output
CT =
" CutoFF" × 16mA
100
4 mA for 4 ÷ 20 mA output
“Lo r”, ”Hi r” - These parameters define the expansion of nominal range in percent. They
determine the permissible range of input currents (Figure7.1).
The permissible range allow user to exceed the nominal range of input current.
If input value is contained in the permissible range a proper result is displayed.
If input current exceeds this range (defined by “Lo r” and “Hi r”), “-Lo-” or “-
Hi-” warning is displayed depend on input current value.

Figure 7.1 Example of definition of permissible range of input currents -
“Lo r” and “Hi r” parameters (“4-20” mode)
The “Lo r” parameter is important if input is set to “4-20” mode only, and determines lower border of the permissible range. If input is set to “0-20” mode, lower border of the permissible range is always 0mA.
If input is set to “4-20” mode, the lower border is calculated due to expression:
I min
= 4 mA - 4 mA × “Lo r” %.
The “Lo r” value can be set from 0 to 99.9%.
Parameter “Hi r” determines the upper border of the permissible range accordingly to the expression (for both “0-20”i “4-20”modes):
I max
= 20 mA + 20 mA × “Hi r” %.
The value of “Hi r” can be set from 0 to 19.9%
In example no 1 of the DISPLAY VALUES CALCULATION paragraph the procedure of the permissible input range determining is presented in details.
If the measurement value do not exceeds permissible measurement range but displayed value exceeds range (-99999 ÷ 999999), the warning
”
-Ov-
” is displayed rather than the calculated result.

- analogue output is controlled due to batcher counter result,
- analogue output is controlled due to total flow counter result.
i
If parameter „SourCE”=„bAt” and batcher mode is disabled, then analogue output will be set to its alarm state defined by „AL” parameter in „OutPUt” menu.
”OUt LO” - this parameter determines the input value for which the output signal is minimal
(depend of output mode „OUtmod”).
“OUt HI” - this parameter determines the input value for which the output signal is maximal
(depend of output mode „OUtmod”).
The analogue output value is calculated due to formula given below:
Out=
W −" OUt LO"
"OUt HI" −"OUt LO"
×
B−AA
i
where:
W – displayed value,
Out – analogue output value,
B
– higher range limit (20mA / 5V / 10V),
A – lower range limit (0mA / 4mA / 0V / 1V / 2v),
“Out LO” parameter can be greater than “Out HI”. In this case the conversion characteristic is reversed, it means that if input value raises the output value falls.

”Lo r”, ”Hi r” - this parameters define the output value range. If calculated output value Out exceeds defined range then analogue output generates signal equal to upper or lower border of the defined range. These parameters defines the percentage extension of nominal analogue range (with 0,1% resolution).
Parameter “Lo r” defines lower border of the range due to formula:
Out
min
= A - (A × “Lo r” %), where:
A – lower signal value range limit.
This parameter can be set from 0 to 99.9% (for active current output and active voltage output) or from 0 to 29.9% (for passive current output).
Parameter “Hi r” defines higher border of the range due to formula:
Out
max

This menu is connected with RS-485 interface, and sets his properties:
”Addr”
- this parameter defines the address of the device, accordingly to Modbus protocol.
It can be set in range from 0 to 199. If the value 0 is set then device, responds to frames with address 255 (FFh).
47
User manual - FLOW METER SPP-N118
”bAud” - this parameter determines RS-485 interface baud rate. It can be set to one of 8 possible values: ”1200”, ”2400”,”4800”, ”9600”, ”19200”, ”38400”, ”57600”,
”115200”.
”mbAccE”
- this parameter sets the access to the configuration registers of the device.
Possible values:
”on”
”oFF”
- configuration registers can be set via RS-485 interface,
- configuration registers can not be set via RS-485 interface.
i
The access to registers no 04h i 05h cant be denied by ”mbAccE” parameter (see:
LIST OF REGISTERS).
”mbtimE” - this parameter defines maximal time (sec) between following frames received by the device. If the delay will be greater than the value of ”mbtimE” parameter, the relays and the analogue output which are controlled via RS-485 interface, will set to alert state (see "OUtPUt" menu and “rELAy1” menu description). Parameter
“mbtimE” can be set to values from 0 to 99 seconds. The value 0 means that the time will be not controlled.
”rESP”
- this parameter defines minimal (additional) delay between the Modbus message and the answer of the device (received and sent via RS-485 interface). This additional delay allows the device to work with poor RS-converters which do not works properly on baud rates higher than 19200. This parameter can be set to one of values:
- answer as quick as possible, no additional delay
”Std”
” 10c”
” 20c”
” 50c”
”100c”
”200c”
- answer delayed of 10, 20, 50, 100 of 200 chars respectively, where one character time depends on selected baud rate
i
In the most cases parameter ”rESP” should be set to ”Std” (no additional delay).
Unfortunately for some third party RS-converters ”rESP” should be adjusted
experimentally. Table 7.1 contains most frequently used values.

User manual - FLOW METER SPP-N118
The input of the device is equipped with over-current protection circuit. This circuit protects the standard resistor to damage. Maximum input current is set to 40mA.
When temperature of the standard resistor falls, the protection circuit will turn off himself automatically, and the device will measure the input current again. Due to thermal phenomenon in the standard resistor, precision of the measurement may be lower, during few minutes (up to the standard resistor temperature will falls to the environment temperature).
The first step to compute the result of measure is the calculation of the normalized result
(it means result of 0-1 range). To do it, the begin of the input range (0 mA for 0-20mA range, and 4mA for 4-20mA range) must be subtracted from measured value. Next, received result must be divided by the width of the input range ( it means 20mA for 0-20mA range, and 16mA for 4-20mA range). So normalized result can be expressed by expressions:
i
I n
=
I n
=
I inp.
−
4
16
I inp.
20
for
4 ÷ 20 mA range
for 0 ÷ 20 mA range where I inp.
Means input current (in mA), and I n –
normalized result.
If measured value exceeds the nominal input range (0-20mA or 4-20mA), and do not exceed the permissible input range, then received normalized I n
result will exceed 0-1 range, e.g. input range 4-20 mA, input current = 3 mA – the normalized result is equal -0,0625, and for input current = 22 mA, the normalized result is equal
1,125. In such cases presented expressions are still correct.
9.1. ADDITIONAL CALCULATIONS (USED CONVERSION CHARACTERISTIC)
The manner of the additional computation of the displayed result depends on selected conversion characteristic. All presented charts are connected with the input range 4 - 20 mA.
9.1.1. Linear characteristic
The normalized result is converted by fixed coefficients determined by “Lo CAL” and
“Hi CAL” parameters (when the normalized results is equal 0, then value “Lo CAL” is displayed, and when the normalized results is equal 1, then value “Hi CAL” is displayed).
Expression presented below shows the manner of result calculation:
W =I
n
×
"Hi CAL"−"Lo CAL" "Lo CAL" , where W means the displayed value.
i
The value of the “Lo CAL” parameter can be higher than the value of “Hi CAL” parameter. In such a case, for an increasing value of input current the displayed value decreases.

9.1.4. User defined characteristic
User defined characteristic is defined as set of X-Y points. Number of the points is variable and may be set from 2 to 20 points which make linear segments (see graph and see ”FLouu”
menu).
Due to the normalized result I from figure below, and I n be chosen. n
, the device computes specific segment, e.g. for characteristic
= 0,65 the segment between points X = ”50.0.” and X = ”70.0.” will
Let's mark those points as PL (point low) i PH (point high) - in this example PL= “50.0,” and
PH = “70.0.”, and the normalized result I n

9.2. EXAMPLES OF CALCULATIONS
Example 1 : Selection of the permissible input range (“4-20” mode)
If in “4-20” mode the user sets “Lo r” = 20,0% and “Hi r” = 10,0%, then permissible input currents range will be equal: 3,2 mA ÷ 22 mA. Lower border of the range is the result of calculations: 4 mA - 4 mA × 20%, and the higher : 20 mA + 20 mA × 10%.

Let the input mode = 4-20 mA. The normalized I

= 10 mA then 10 mA - 4 mA = 6 mA, and this result should be divided by the width of input range (16 mA). Finally the normalized result: I n
= 6/16 = 0,375.
In case when input current exceeds nominal measurement range, calculations are similar. For example if input current is equal 2,5 mA then I equal 20,5 mA then I n
= (20,5 - 4)/16

Example 7 Current output value calculation
Lets assume that we have active current output and its parameters are:
“OUtmod” = “4-20”, “OUt LO” = 100, “OUt HI” = 200, “Lo r” = 5.0, “Hi r” = 5.0
Parameters “Lo r” and “Hi r” define working range of current output to 3.8 ÷ 21 mA.
Output current will be calculated for three displayed values „D”: a) D = „17.5”
According to formula from page 44:
I out
= (17.5-10.0) / (20.0-10.0) × 16 mA + 4 mA = 0.75 ·16 + 4 = 16 mA
Calculated I out
does not exceed the output working range (3.8 - 21 mA).
58
User manual - FLOW METER SPP-N118
b) D = „20.5”
According to formula from page 44:
I out
= (20.5-10.0) / (20.0-10.0) × 16 mA + 4 mA = 1.05 ·16 + 4 = 20.08 mA
Calculated I out
does not exceed the output working range (3.8 - 21 mA).
c) D = „30.0”
According to formula from page 44:
I out
= (30.0-10.0) / (20.0-10.0) × 16 mA + 4 mA = 2 ·16 + 4 = 36 mA.
Calculated I out exceeds the output working range (3.8 - 21 mA), so current output will generate current equal to the upper border of range defined by parameter “Lo r” i “Hi r” (it means 21 mA).
Example
It is necessary to measure the pipeline flow using orifice plate (flange), which makes a pressure difference 25 kPa, at flow rate 10 m 3 /h. Measurement can be done using differential pressure sensor with range 25kPa, and current output signal 4-20mA. The sensor output
should be connected to SPP-N118 terminals, and proper configuration of input and
recalculation is required.
Let meter measures with precision 0,1 m
3
/h, parameters of “Flouu” menu should be set as below:
“I tyPE“ = “4-20mA” - current input type
“I CHAr“ = “Sqroot”
- input characteristic – square-root. It is necessary to obtain flow rate readings direct proportional to pressure difference (using
“Point” = “0.0” differential pressure sensor proposed in example).
- decimal point position, it allows to obtain displaying precision
0,1 m
3
/h
“F unit” = “m 3”
“Ftunit” = “hour”
- parameters defining the unit flow as m 3 /h
“Lo CAL” = “000.0”
“Hi CAL” = “010.0”
- value displayed when input current is equal 4mA - 0,0 m 3 /h
- value displayed when input current is equal 20mA - 10,0 m
3
/h
Parameter “FiLtEr” and “CutoFF” should be set if necessary. If it is necessary to input current lower than 1% (it means 4.16mA) stop total flow counter incrementation then
“CutoFF” parameter should be set to value “1.0”.
If user would like to protect input signal from the noise (to stabilize measurements), then parameter “FiLtEr” should be set to value allowing easy readings.

Transmission parameters: 1 start bit, 8 data bits, 1 or 2 stop bit (2 bits are send, 1 and 2 bits are accepted when receive), no parity control
Baud rate: selectable from: 1200 to 115200 bits/second
Transmission protocol: MODBUS RTU compatible
The device parameters and display value are available via RS-485 interface, as HOLDINGtype registers (numeric values are given in U2 code) of Modbus RTU protocol. The registers
(or groups of the registers) can be read by 03h function, and wrote by 06h (single registers) or
10h (group of the registers) accordingly to Modbus RTU specification. Maximum group size for
03h and 10h functions can not exceeds 16 registers (for single frame).
i
The device interprets the broadcast messages, but then do not sends the answers.
10.1. LIST OF REGISTERS
Some parameters are located on two registers (higher word in first register, and lower word in next one). After writing of one of them device controls result of their 32-bit value, and if it is necessary corrects value of second register automatically. If appropriate modification is impossible, both registers stay unaffected and device responds with error code 03h
(see: TRANSMISSION ERRORS DESCRIPTION).

- it is recommended to read these registers simultaneously – (1,2) and (7,8), (D3h,D4h) in 2-registers frames, and registers (9h,Ah,Bh,Ch) in 4-registers frames. If single registers are read, data errors are possible because of changes of read value between successive registers readings. Zeroing of total flow counter is possible by preset of
0000h to any one of it's registers (09h ÷ 0Ch). Controlling of batcher counter is possible by writing appropriate value (0 - zeroing, 1 - start/continue, 2 - pause) into one of the batcher counter registers (0Dh ÷ 0Fh). Zeroing of
number of batches counter is possible by preset of 0000h to any one of it's registers (D3h ÷ D4h).
2 - these registers are active only if device is equipped with current or voltage output
3 - after writing to register no 20h the device responds with an “old” address in the message.
4
5
- after writing to register no 22h the device responds with the new baud rate.
- the value of the “mbAccE” parameter is also connected to write to this register, so it is possible to block a writes, but impossible to unblock writes via RS-485 interface, The unblocking of the writes is possible from menu level only.
- the pairs of „X -Y” coordinates may be defined for any free point. The pair is “free” (it means that particular point is not defined) if „X” coordinate of this point is equal 8000h. After writing both X and Y coordinate the point is defined and used in calculation of result. The coordinates of any point can be changed at any time.
10.2. TRANSMISSION ERRORS DESCRIPTION
If an error occurs while write or read of single register, then the device sends an error code according to Modbus RTU specifications (example message no 5).
Error codes:
01h - illegal function (only functions 03h, 06h and 10h are available),
02h - illegal register address
03h - illegal data value
08h - no write permission ( see: “mbAccE” parameter)
