GENERAL INFORMATION ON THE INSTALLATION
Flow direction
ISOIL
Before install the sensor locate the direction of
the liquid in the piping
?
The sign of the flow rate is positive, when the flow direction
it’s (from – to +) as printed on the tag plate.
If after the installation, for plant request becomes
necessary reverse the sign of the flow, it's enough reverse
the sign of the coefficient KA
- FLOW DIRECTION +

If the sensor has to be mounted on a pipe made of
an insulating material, then for grounding purposes of
the liquid there are two possibility:
Install two metallic ring (available on request)
between the sensor flanges and the counter flanges of
the pipe line; or:
Use a sensor with the additional grounding electrode.

taken:
1) Grounding metallic rings should be provided to
ground the liquid
2) the sensor should be insulated from the piping,
using gasket between the rings and the sensor
and insulating bushes for the tightening tie
rods.
The flanges pipe should be connected one to
the other (by-passing the sensor) with a
copper plait 6 mm2 section.

BLOCK LEVELS
If for several reasons you need to change the level of block of the instrument, follow the steps:
?? Set the dip switch on OFF position (opposite side than the lock symbol, see pict. On page 32)
?? Access the Main Menu (see page 32)
?? Press several times the key
, till you don’t reach the menu “11: Internal data” and then press
?? Press the key
and
to enter the function “Block level”
?? Choose the desired level of block by pressing the key
and confirm the choice by pressing the key
To enable the level of block you selected place back the DIP switch to the original ON position marked with a lock symbol
(see pict. On page 32)
The available levels of block are the following:
Level 0:
it completely disables the access to the functions. You can perform the following functions through the keyboard:
?? Changing the display mode
?? Dosing Start/stop (when such a function is enabled)
?? Data printing (when such a function is enabled)
Level 1:
it enables the access to the following functions:
?? Totalisers re-setting
?? Dosing functions modifications
Level 2:
it enables the access to the following functions:
?? Quick start menu (see code level 2 = 11111)
?? Scale (full enabling)
?? Display (partial enabling)
?? Diagnostics (partial enabling)
Livello 3:
it enables the access to all the functions of level 2
When the Dip-switches are on OFF position, all the functions are enabled.
The functions requiring an access code higher than L2 are reserved to the service.

Set the length of the cable connecting the sensor to the converter (measure unit: meters).
N.B.: the length must be set in multiple of 10m
(POS. 5) Test “empty pipe” [E.P. DETECT=
XXX]
This function enables/disables the empty pipe detection feature. Herewith we remind that in case of noise on
the cable or on the electrodes this system may fail and therefore should be used carefully. To determine the
empty/full pipe condition the signal is analysed within a one second time window. In case the pipe is detected
to be empty, then the measure is lock. For a proper behaviour a calibration of this function should be
performed in site as described below. Its value hat to be either ON or OFF.
(POS. 6) “Autozero” calibration [AUTOZERO CAL.]
This function enables/disables the automatic zero calibration system. It is necessary to perform this function at the
first sensor installation or after a long period the sensor has been empty. To perform the sensor it is absolutely
necessary the sensor is full of liquid and that the liquid is perfectly staying still. Even very small movement of the
liquid may effect the result of this function, and, consequently, the accuracy of the system. Once you are sure the
a.m. conditions are fulfilled (and when the percentage flow rate value is stable) press for more than one second the
key
. Check the percentage flow rate value goes to zero, otherwise repeat the operation again. When the value is
stable at zero, then press
.

(POS. 7) “empty pipe” calibration [E.P. CALIBR.]
this function enables/disables the automatic calibration procedure of the empty pipe detection function. Before
enabling this function, the Empty Pipe test should be enabled first as above described. Before performing this
function, the sensor has to be completely filled in with the liquid so that both the lining and the electrodes are wetted.
The sensor has then to be emptied again and then you should press the key
: the operation will have to be
confirmed by pressing the key
or cancelled by pressing the key
. By this function the system sets the value of a
parameter which could also be manually changed (see function “E.P.thr” within the menu 4-ALARMS).

Full scale value set for range N.1. There are four fields to fill in order to set this parameter, from left to right: 1) volume unit of
measure, 2) type of unit, 3) time unit of measure and 4) numeric value. The selection is made by positioning the cursor on the field
to modify. To change the type of unit of measure (metric, British or American, mass or volume) the cursor has to be positioned on
the symbol “/” (field N. 2). When the nominal diameter is set to zero it is possible to modify only the numeric field, since the unit of
measure stays at m/sec.
The following tables show the units of measure available and the conversion factor by comparison with 1 dm3 and 1
kg. The converter accepts any kind of combination of units of measure satisfying both the following conditions:
?? Numeric field value ? 99999
??

Setting of the volume corresponding to each pulse of channel 1 and totalizers unit of measure. There are three fields
to fill in to set this parameter, from left to right: 1) unit of measure, 2) type of unit of measure and 3) numeric value.
The selection is performed positioning the cursor on the field to modify. To change the type of unit of measure
(metric, British or American, mass or volume) just position the cursor on the blank space between the unit of measure
and the numeric value. Then the nominal diameter is set to zero, it is possible to modify only the numeric field since
the unit of measure stays at metre (m). the possible units of measure are those above described.
This function is active only if the pulse emission on channel 1 has been set as enabled.
(POS.11) Pulse value channel 2 and unit of measure of the totalizers [IMP2=dm³
X.XXXXX]
Setting of the volume corresponding to each pulse of channel 2 and totalizers unit of measure.
This function is identical to the previous one and is active only if the pulse emission on channel 2 has been set as
enabled.
(POS.12) Pulse duration channel 1 [TPUL1=ms
XXXX.XX]
Setting of the duration of the pulse generated on channel 1. Its value is expressed in milliseconds and has to be
between 0.4 and 9999.99. When the high frequency output is present, then the minimum value can go down to 0.04
milliseconds.
ATTENTION: since the instrument cannot detect which type of device it is connected to, it is up to the user to verify
the set pulse duration is compatible with the external device processing such pulses. If, by example, an electromechanical pulse counter is connected, then two kind of problems may occur: if the pulse is too long than the totalizer
coils may burn or, if it too short, the counter may not count, even damaging the converter output.
This function is active only when the pulse emission function on channel 1 is enabled.

Time constant set. This parameter effects the integrating filter making the instrument response quicker or slower,
according to the set value. A higher value corresponds to a more stable but slower measure, a smaller value the
opposite. The most common values are from 1 to 5 seconds. The value of this parameter has to be within the range
from 0 (integral filter disabled) to 6000.0 seconds. The following diagram shows the response of the instrument for a
flow rate variation from 0 to 100% within the T time constant period:

(POS. 18) Acceleration threshold [SKIP THR=%
XXX]
Acceleration threshold set. The acceleration threshold stands for the limit beyond which a flow rate variation
determines an immediate response at the output, without being filtered by the time constant. This system allows the
instrument to have an immediate response in case of big variations of the flow rate, filtering (and delaying) the
response to small variations. The result of that is a very stable measure, ready to follow the process. The value is set
as percentage of the full scale value from 0 to 125%. If such a value is set to zero any flow rate variation bigger than
0.5% of the full scale value will immediately effect the outputs.
The following diagram shows the instrument response in two cases: a flow rate variation from 0 to 10% completely
absorbed by the time constant effect and a variation form 10% to 100% exceeding the acceleration threshold and
then immediately sent to the output. In actual fact there is always a minimum time between the measure acquisition
and the outputs update. For the ML190 and ML200 this time in the worst case is around 140 ms as far as the 0/4…20
mA output is concerned.

(POS. 19) Peak cut off threshold [PEAK THR=%
XXX]
Anomalous signal pick cut off threshold set. This parameter allows to set the maximum value of deviation of the actual
measure sample by comparison with the average one. If the new value is higher than the set limit, than such a value
is “cut” to the limit value. This function is used to make the meter less sensitive to big perturbations on the flow rate
measure, as it may happen when there are solids in suspension in the liquid hitting against the electrodes determining
a high electrical noise. The permitted values of this function go from 0 to 125 % and are referred to the full scale
value. If this parameter is set to zero the peak detection function is disabled and any new measure ample will be
accepted and processed as it is by the converter.
(POS. 20) Low flow zero threshold [CUT-OFF=%
XX.X]
Low flow zero threshold set. When the flow rate value falls below this parameter the flow rate is assumed to be zero
and set to such a value by the converter. This parameter can be set from 0 to 25.0% of the full scale value. When this
parameter is set to zero this function is disabled.
(POS. 21) Auto-calibration [AUTOCAL=
ON/OFF]
Enables/disables the auto-calibration function. When enabled the converter performs a calibration cycle once every
hour. During such a cycle the measure is “frozen” at the latest measured value. The calibration lasts from 8 to 15
seconds from case to case and allow to remove completely the thermal derivation error effects on the measure. This
function is recommended to be enabled is the instrument undergoes strong temperature variations during its working.
When the meter is used in batch applications and in any case you want to compensate temperature drift effects, then
the automatic calibration procedure is recommended before any batch process enabling it via the external on/off
input. This is because during the calibration cycle the meter does not register any flow rate variation.
Allowed values for this parameter: ON / OFF.

C:\UFFICIO TECNICO\MANUALI\ML200\ML200 INGLESE\
(POS. 22) Automatic scale change enable [AUTORANGE=
ON/OFF]
Enables/disables the automatic change of scale. The meter may have two different working ranges in order to suit to
the variable process conditions. In order to get the best results out of this function it is important range N.2 is bigger
than N.1. When the flow rate increases and reaches the 100% of the full scale 1, then the meter automatically
switches to scale N.2. When the flow rate decreases again reaching a value on scale 2 equal to the 90% of full scale
N.1, then the active scale is N.1 again.
Allowed values for this parameter: ON / OFF.
N.B.: the autorange doesn’t allow to use the manual change of range (see pos. 36)
(POS. 23) Energy saving enable [E.SAVING=
ON/OFF]
Automatic energy saving function enable. This function is used when the instrument is powered by a battery or solar
cells, allowing an energy saving up the 60-80. The energy consumption is controlled by the ratio between the
measuring cycles powering the coils and the cycles without powering the coils. When the flow rate is stable the
number of “off” cycles is higher than the “on” ones, so that the average consumption is strongly reduced. If the flow
rate suddenly changes, then the meter switches on a higher number of measuring cycles, in order to get a higher
response time, switching off the cycles as soon as the flow rate gets back to be stable. If the flow rate varies below of
“acceleration threshold” percentage value, then the meter goes on with “off” cycles, but as soon as the flow rate
value exceeds such a threshold, the meter switches on many measuring cycles again. The speed the meter switches
on and off the excitation cycles is different: from a constant flow rate to a variable one it is a very fast process, while
from variable flow rate to a stable one such a process is much slower.
Allowed values for this parameter: ON/OFF
N.B.: to optimize this function it is raccomended choose a value for the acceleration threshold within 10÷15

(POS. 24) Maximum flow rate threshold [MAX THR=%
XXX]
Maximum flow rate value alarm set. When the flow rate value exceeds such a threshold as absolute magnitude
(i.e. not considering the sign), then an alarm message is generated. The value of this parameter is expressed as
percentage of the full scale value and may be set from 0 to 125%. To set this parameter to zero corresponds to
disable the alarm generation.
(POS. 25) Minimum flow rate threshold [MIN THR=%
XXX]
Minimum flow rate value alarm set. When the flow rate value falls below such a threshold as absolute magnitude
(i.e. not considering the sign), then an alarm message is generated. The value of this parameter is expressed as
percentage of the full scale value and may be set from 0 to 125%. To set this parameter to zero corresponds to
disable the alarm generation.
(POS. 26) Hysteresis [HYST=%

Hysteresis threshold set for the minimum and maximum flow rate alarms.
(POS. 27) “Empty pipe” detection threshold [E.P.THR=

(POS. 28) Current output value in case of failure [mA VAL.FAULT =%
XXX]
Setting of the value the 0/4...20 mA current output has to be in one of the following cases:
?? empty pipe
?? coils interrupted
?? ADC error
49
C:\UFFICIO TECNICO\MANUALI\ML200\ML200 INGLESE\
The allowed range is from 0 to 120% of the 0..20 mA scale, 120% corresponds to 24 mA and does not depend on the
selected range (0…20 / 4…20 mA).
The NAMUR NE43 recommendations ask for a alarms signalling value for the current output lower than 3.6 mA
(<18%) or bigger than 21 mA (>105%). It would then be preferable to set the value of this function at the 10%, so
that the current value in case of the a.m. cases would be 2 mA, allowing the following diagnostics:
?? current < 2 mA - 5%: line interrupted, power supply failure or faulty converter;
?? 2 mA -5% ? current ? 2 mA + 5%: hardware alarm;
?? 4 mA ? current ? 20 mA: normal working range;
?? 20 mA < current ? 22 mA: out of range, measure above 100% f.s.
(POS. 29) Frequency output value in case of failure [Hz VAL.FAULT=%
XXX]
Setting of the value the frequency output has to be in one case of the following cases:
?? Empty pipe
?? Coils interrupted
?? ADC error
The allowed range is from 0 to 125% of the frequency full scale value.
Although there are not specific rules regulating cases like this one, it would be convenient to use the failure information
as follows:
?? 0% Hz ? frequency ? 100% f.s.: normal working range;
?? 100% f.s. < frequency ? 110% f.s.: overflow, measure above the 100% of the f.s.;
?? 115% f.s. ? frequency ? 125% f.s.: hardware alarm condition.

Enable one of the following functions to enable and program the batch on the converter:
Menu:
5.INPUT:
- BATCH (page 52 pos. 37)= Enable this function (on)
Menu
6.OUTPUT:
OUT.1/OUT.2 (page 52 pos. 38-39) = BATCH AND PRE-BATCH
The value of batch (quantity batch) is setting from visualizzation page (see page 63)
Output for pre-batch:
6.Output:
OUT.1=
END BATCH*/PREBATCH*
OUT.2=
END BATCH*/PREBATCH*
END BATCH = output signal of end batch, PREBATCH = output signal of pre-batch
When the “batch outputs” are enable is possible to set the values of pre-batch and compensation:
VPRE=
pre-batch value: set the volume of liquid at which you want to enable the pre-batch.
At the pre-batch volume “V Pre” the output (if enabled) is de-energised.
This value is constant for all quantity to batch and must be set in current unit of measure of volume
The pre-batch function is useful when you need fast and accurate fillings.
VCOM=
Compensation value: set the volume dosed in excess because of
system delays, like valve closure, pump stop, motor stop, etc.. It is recommended to run some test batch to learn this
value.
N.B.: the output functions, for batch (batch and prebatch) can be also associate to the additonal module outputs

ND SELECTION
The suitable nominal diameter can be
determine by means of the tables aside.
The flow velocity is also determined by the
fluid properties:
-
-
for “acqueous” solutions, full scale
velocity within: 0,4÷10 m/s
for fluids tending to form deposits within
the measuring section, should be above
2 m/s
for abrasive fluids, the velocity must be
less than 2 m/s
If there isn’t any specific full scale indication,
the intrument is calibrated at a f.s. flow rate
corresponding to a 3 m/s liquid speed
