ATTENTION:

USE OF VOLUME &

WEIGHT CALCULATIONS

The

Bulk

Sonics

® line of ultrasonic equipment makes a direct measurement of the distance between the sensor and the material surface. This equipment does not measure the volume or weight of the material within the vessel. The QUEST+ software can perform calculations to display the volume and weight of the material.

These calculations are based upon the distance measurement and the vessel dimensions and material bulk density entered by the user during setup.

NOTE: The calculated volume and weight values should be considered "estimates". Monitor Technologies LLC accepts no responsibility for the accuracy of the calculated and displayed volume and weight values. The accuracy (not stated or warranted) of the volume/weight calculations are effected by the fluctuation and accuracy of various factors. These factors include, but may not be limited to, actual vessel dimensions, sensor mounting location, sensor aiming, angle of repose (negative and positive), material bulk density, material flow properties (ratholes, bridging, etc.), material inlet/discharge locations, and material packing.

Please consult the factory to discuss applications where volume/weight is of critical importance.

The

Bulk Sonics

® ultrasonic continuous level product line consists of smart transmitters as well as sensor/controller systems (See Bulletins 334E and 334F). The smart transmitters consist of a sensor mounted at the top of the tank or silo with integral mounted electronics controller with local display (optional on LST models) and outputs. The smart transmitters are available for solids and liquid applications. The transmitter’s sensor is a non-contact device with no moving parts.

Make sure that no object with a reflecting surface protrudes into the ultrasonic beam of the smart transmitter

(See Figure 1 for typical beam angle. Actual dimensions may vary.). Due to their narrow beam angle and unique signal processing features, the

Bulk Sonics

smart transmitters can tolerate smaller objects (E.g.: probe of a limit switch, smooth vessel wall) within the sonic cone, however, avoid these whenever possible.

The

Bulk Sonics

smart transmitters are available in two configurations, those used specifically for solids (SST: solids smart transmitter) and those used specifically for liquids (LST: liquid smart transmitter). Models include the

SST-15, SST-30 and SST-40 for solids applications and the LST-20, LST-40, LST-50 and LST-80 for use with liquids. Each model can provide accurate level measurement in a variety of difficult applications.

The

Bulk Sonics

® ultrasonic continuous level measurement product line utilizes the principles of ultrasonic technology to provide accurate level measurements in solids and liquids storage vessels as well as open channel flow metering applications (LST models only).

Sensor Dead Zone:

This is a feature common to all ultrasonic continuous level measurement devices. Each smart transmitter’s sensor has a “dead zone” (distance from the sensor face) within which the unit is unable to measure. The dead zone for

Bulk Sonics

Smart Transmitters are as follows:

SST-15 = 3.3ft (1.0m)

SST-30 = 2.0ft (0.6m)

SST-40 = 2.0ft (0.6m)

LST-20 = 2.0ft (0.6m)

LST-40 = 1.5ft (0.45m)

LST-50 = 1.2ft (0.35m)

LST-80 = 0.8ft (0.25m)

Ultrasonic pulses are emitted from the transmitter’s sensor into the tank or silo and reflected back from the surface of the material. A reflected pulse is called an echo.

The distance measurement from the sensor to the material is directly related to the duration of time necessary for the echo to return to the sensor. The intelligent electronics in the smart transmitter interfaces with the sensor and processes the received signal from the sensor to display the measured distance/level and generate all output signals. Smart transmitters have an analog output and a relay (4-wire version only) and can be equipped with

HART

® communications option.

Beam Angle:

A total beam angle of 5-7˚ at

–3db exists on

B u l k S o n i c s

® smart transmitters. A small beam angle is important for s u c c e s s f u l application of ultrasonic technology. This

Figure 1: Diameters corresponding to 5˚ beam angle

can ensure a reliable measurement in narrow vessels, vessels with protruding objects and focuses the sound energy for good penetration through gases, vapor, foam and dust. Consult the product specifications for the total beam angle for the specific smart transmitter you are using.

In solids level measurement (SST models only), due to the angle of repose, the smart transmitter can usually be located such that the dead zone is not an issue. In liquid level measurement (LST models only), if measurement within the dead zone distance is critical, the transmitter may need to be recessed with a standoff pipe or mounting neck (See Choosing the Transmitter Location for Liquid

Level Measurement Applications).

Choosing The Transmitter Location:

Model LST (Liquid Level Measurement Applications): The best location for a smart transmitter is 1/4 to 2/3 the diameter of the tank away from a sidewall and in a location where it does not interfere with incoming material or any fixed internal obstructions within the vessel.

1) Do not install the smart transmitter above material inlet flow paths or internal objects, e.g.: cooling pipes, ladders, bracing members, thermometers, etc (Figure

2).

2) Mount the smart transmitter with its face parallel to the liquid surface ±

2-3˚ (Figure 3).

3) In agitated tanks, position the smart

Figure 2

transmitter where the material surface is flat. Try mounting it closer to the sidewall where the liquid surface may form a less steeper angle of repose. In case of heavily agitated tanks with a steep angle of repose ultrasonic measurement may not be possible (Figure 4).

4) The smart transmitter should be protected against overheating

Figure 3

3

(e.g. by direct sunshine) to avoid inaccurate measurements (Figure 5).

5) Foaming of the liquid surface may render ultrasonic level metering impossible. If possible, a location should be found where foaming is the smallest (the device should be located as far as possible from liquid inflow) or a stilling pipe or well should be used.

assembly is provided on all model SST smart transmitters and is required for aiming. As a rule of the thumb and to comply with the above requirements:

1) Position transmitter as far away from the fill inlet point(s) of the silo as possible (See Figure 7).

2) In applications where the material is pneumatically conveyed into the vessel, position the sensor where the speed of material inflow is at its lowest value (See

Figure 8).

Figure 4

Figure 5

6) Mounting liquid smart transmitters on standoff pipes is also possible (See Figure 6). The structure of the standoff pipe should be rigid. The inner rim where the ultrasonic beam leaves the pipe should be rounded.

For minimum dimensions refer Table 1.

Figure 7 Figure 8

3) Make certain you can aim the smart transmitter’s sen-sor towards the discharge/outlet of the silo (See Figure

9).

Model SST (Solids Level Measurement Applications): The best location for a smart transmitter is 1/6 to 1/2 of the diameter of the silo away from a sidewall. The smart transmitter should be mounted in a location where it can be properly aimed at a point representative of the average material level and not be interfered with by incoming material or internal obstructions. A joystick mounting

(manhole) covers, access lids, or for instance on a steel structure lowered into a larger opening on the roof, e.g.: 20 by 20 inch / 500 x 500 mm. This solution is to be used with roofs thicker than 14 to 15 inch / 350 to 380 mm.

5) Silos constructed of concrete may require special provisions to prevent the edges of the hole from interfering with the beam. If the entire tilting range of the joystick is required (±20˚), then the thickness of the concrete roof can not exceed the value as specified in Table 2.

Open Channel Flow Measurement:

(Liquid Smart Transmitters Only) For the best possible performance and measurement accuracy, the smart transmitter should be installed as close to the expected maximum liquid level as possible. However, the transmitter should NOT be so close to the maximum liquid level as

to be within the transmitter sensor’s dead zone (Refer to section on Sensor Dead Zone and Specifications for measuring range).

Install the device upstream in a place defined by the characteristics of overflow and metering channel along the longitudinal axis of the flume or weir.

From the point of view of measurement accuracy, the length of the channel sections preceding and following the measuring flume and their method of joining to the measuring channel section are of critical importance.

Despite even the most careful installation, the accuracy of flow metering will be lower than that specified for distance measurement. The features of the flume or weir used determine measurement accuracy.

Choose the best location for the smart transmitter according to the Pre-Installation Considerations section. according to the diameter of the transmitter and hole pattern of the flange.

4) Attach the flange to the vessel using 1/2” to 3/4”/M12 bolts.

5) Aim the sensor using the joystick/flange assembly (See

Aiming), then tighten the ball-joint housing (maximum

2.58ft-lbs/3.5 Nm).

Installation from inside the vessel: If the roof opening for any reason can not be as big in diameter as the transmitter (See Figure 10):

1) Push the unit out of the silo (upwards) (See Figure 10,

Item 1).

2) Remove the split insertion from the flange and put the flange around the joystick (See Figure 10, Item 2).

3) Slide the insertion back to its place (See Figure 10,

Item 3).

4) Screw the ball-joint housing to the flange with the (4)

1/2” to 3/4”/M12 bolts and tighten only to such an extent that will allow free movement of the aiming arm around the ball joint for the aiming process (See Figure

10, Item 4).

5) Cut and drill the appropriate holes on the vessel

Liquid Level Measurement Applications:

(Models LST only)

LSTs with threaded connection: Thread the device into the coupling and tighten using the wrench flats provided on the sensor part.

Never attempt to tighten the transmit-

ter by its housing! Once the transmitter is screwed tight, rotate the housing (max. 300˚) to reach the desired cable outlet position.

LSTs with flange: Mount a counter flange on the tank according to the diameter of the transmitter’s sensor and hole pattern of the flange. Attach the flange to the counter flange using 1/2” to 3/4”/M12 bolts.

Solids Level Measurement Applications:

(Models SST only) Although it may be most convenient to mount the transmitter on a removable port cover, the best location may be elsewhere. Consult the factory for approval of the mounting location. Engineering drawings or properly dimensioned hand sketches are adequate for communicating with the factory.

SPLIT-FLANGE SEALING AFTER INSTALLATION

When using flanges with the “split insertion” feature it is critically important to seal the “split joint” with a sealant that can withstand the particular environment

(RTV, etc). Failure to seal the joint may permit moisture to penetrate the vessel.

Standard Installation:

1) Remove the split insertion from the flange and put the flange around the joystick.

2) Slide the insertion back to its place and screw the balljoint housing to the flange with the (4) 1/2” to 3/4”/M12 bolts and tighten only to such an extent that will allow free movement of the aiming arm around the ball joint for the aiming process.

3) Cut and drill the appropriate holes on the vessel

Figure 10

according to the diameter of the transmitter and hole pattern of the flange.

6) Screw the flange to the vessel using 1/2” to 3/4”/M12 bolts.

7) Aim the sensor using the joystick/flange assembly (See

Aiming), then tighten the ball-joint housing (maximum

2.58ft-lbs/3.5 Nm).

Aiming:

To reduce weak signal reflection from the material surface caused by the angle of repose, it is recommended to tilt the sensor by the aiming arm of the transmitter. In most cases, the transmitter’s sensor should be aimed towards the middle of the tank/silo bottom by aiming at the silo discharge outlet. In applications where material angle of repose is not present or with tall and narrow silos

(height/diameter

≥ 5) aiming is not critical: i.e. the sensor should face straight down. Refer to the section in Pre-

Installation Considerations entitled “Model SST (Solids

Level Measurement Applications)” for additional information regarding sensor aiming.

electrostatic discharge (EDS), therefore, apply the necessary precautions required to avoid electrostatic discharge, e.g. by touching a properly grounded point before removing the cover of the enclosure.

Unscrew the locking nut on the side of enclosure and tilt the upper part of the enclosure open to access the terminal blocks. Route cable(s) through the 1/2" NPT fittings or

Pg16 cord connectors provided. High voltage wiring

(power input and possibly relay contact) and signal wiring

(analog 4-20mA output; RS-485 communications) must not be led in a common duct or conduit.

Hazardous Location Precautions:

(European Approvals Pending) Observe the regulations listed in the National Electrical Code regarding equipment in hazardous locations. Refer to Specifications for rating of equipment.

Factory Wiring:

Do not alter any factory wiring within the smart transmitter.

Wire only to the terminal connections within the wiring connector or instrument enclosure.

Permanently Connected Equipment:

Disconnecting devices shall be included in the system installation. In installations where multiple circuits are used individual disconnects are required. The disconnects shall be within close proximity of the equipment, accessible to operators, and marked appropriately as the disconnect for the associated circuit. Assure the disconnect ratings are appropriately sized to the circuit protected (refer to Specifications).

Circuit Separation:

Two cable entry locations are provided to aid in maintaining separation of “hazardous live” (typically mains voltages such as 115VAC and 230VAC) and limited circuits

(typically control voltages less than 30Vrms or 42.5VDC).

However, since the smart transmitter’s single wiring compartment can not absolutely protect against physical contact between multiple circuits, it is required that all wiring used must have an insulation rating of 300V minimum, and a temperature rating of 176˚ F (80˚ C) minimum.

Tighten cable glands or conduit connections as well as enclosure cover after installation to ensure proper sealing.

Power Input: (See Figure 11) Smart transmitters can be provided with either a high voltage AC or a low voltage

AC/DC power supply. Verify the specific power supply required for your transmitter by looking at the nameplate on the side of the enclosure. Connect power input wiring in accordance with the diagram in Figure 11. DC powered transmitters can be connected in a 3-wire configuration

(uses the unit’s DC power source to drive the analog output). In this situation, terminals “1” and “6” must be interconnected. Please note that galvanic isolation of the 4-

20mA output will not exist in a 3-wire configuration. Make sure to connect DC powered transmitters with the correct polarity. Improper wiring of the power input will prevent proper operation and may damage the unit.

Analog Output: Wiring for the analog signal should be connected to terminals labeled 6 and 7. Connect wiring for analog output in accordance with Figure 11.

Relay Contact Output: Wiring for the relay output uses terminals labeled 3, 4 and 5. Connect wiring for the contact output in accordance with Figure 11. The SPDT output contact can be used to switch high voltage/high current loads (See Specifications for ratings). Whenever possible, use an independent voltage source to operate the loads.

Follow all electrical codes and use proper wire gauge size.

Protective Earthing:

Each transmitter is provided with an internal and external

“protective conductor terminal” which shall be terminated to the local earth ground potential to eliminate shock hazard in the unlikely event of internal insulation breakdown.

Select wire size that can carry in excess of the sum of all circuits maximum amperage. If the smart transmitter has a plastic housing (optional on some units) use the external “protective conductor terminal”.

QUICKSET Programming:

Recommended as a simple and fast way to start up the smart transmitter. QUICKSET programming is aided by 8 screens (6 for 2-wire units) to set the 8 basic parameters

(6 for 2-wire units) of the transmitter if the required application is uncomplicated level measurement (recommended for liquids only). Other parameters can be modified in the Full Parameter Access programming mode (refer to that section for details).

Attention! The FACTORY DEFAULT for Analog Output and Relay (4-wire units only) calibration is LEVEL. This can be modified only in the Full Parameter Access Mode

(See parameter P01 in the Full Parameter Access section).

A fraction of an inch or a couple of millimeters of fluctuation in the principal measurement value, Distance, will be enlarged by the mathematical calculations. This enlarged fluctuation in displaying Volume/Weight or Flow can (if disturbing) be avoided by setting a rounding factor using this parameter. The rounding factors 2, 5, 10, etc. represent the steps by which the calculated value will be changed in its (one or two) last digit(s).

Values over one million will be displayed in exponential format whereas the value (e) represents the exponent.

(Dead Zone/Band)

This parameter does not need to be altered for standard applications. The

® smart transmitter will not accept any echo within the blocking distance set here.

Level measurement: Far end blocking is used to eliminate incorrect level/volume readings and output actions below a pre-set level. In the far-end of the measuring range, for example, tanks with heaters or other interfering objects

(sludge, cone of silo, etc.) may cause faulty readings.

1) If the level of the process material/medium drops below the blocked out range:

- “Sub 0” will be displayed for the level and volume

- The analog output will hold the value corresponding to the far end blocking level

- Distance value is not interpretable

2) If the process material/medium level is above the blocked out range: The calculation of level and volume will be based on the programmed tank dimensions, therefore, the measured or calculated process values will not be influenced in any way by the far end blocking value.

FACTORY DEFAULT: Automatic Dead Zone/Band Control

Automatic Dead Zone/Band control: (Automatic close-end blocking) By using the factory default value, the unit will automatically set the smallest possible close-end-blocking distance i.e. the dead band.

Manual Dead Zone/Band control: (Manual close-end blocking) Manual close-end-blocking would be used, as an example, to block out the echo originating from the bottom rim of a stand-off pipe or from any object protruding into the ultrasonic cone near the smart transmitter.

By entering a value higher than the factory default the minimum measuring range will be extended and fixed to the specified value.

To display the factory default of the minimum measuring distance press NEXT +

- Indicate “No Flow” on the Display

- Hold the last valid data on the analog output

Only for special applications (measuring range is reduced to 50% of the nominal value).

The measuring window is inactive and the transmitter will respond practically instantly to any target. Recommended for fast target tracking, but usually not applicable for level metering.

These parameters must not be smaller than the fastest possible filling/emptying rate of the actual technology.

For all other applications, use the factory default setting.

1) Set P23 for a=1, confirm it with [E] and switch to Measurement Mode then return to Programming Mode.

2) Observe the change of echo amplitude in P72 and record an average value.

For the time of echo-loss, display and analog output will hold the last value.

In case of echo-loss during filling, the reading on the display and the analog output will shift towards the "full" tank/silo state with a level elevation rate (filling speed) as set in P26.

Immediate In case of echo-loss, the display will immediately change to “no Echo” and the outputs will change according to the "Error Indication Mode" as set in P12.

No echo-loss Echo-loss may occur in completely empty tanks indication in case of with a spherical bottom due to deflection of the empty tank/silo ultrasonic beam, or in case of silos with an open outlet.

If the echo is lost when the tank/silo is completely empty, the indication will correspond to empty tank, in all other cases echo-loss indication will function according to the “Delayed” setting mentioned above.

A “Measuring Window” is formed around the echo signal.

The position of this measuring window determines the flight time for calculation of the distance to the target.

Use this parameter if the Smart

Transmitter unambiguously selects a wrong echo. For example: the echo reflected from the surface is much weaker than the interfering one(s).

Recommended for applications where the vapor/gas is more or less homogeneous. If it is not, the accuracy of the measurement can be improved using the 32-point linearization (

P48, P49).

For sound velocities in various gases see the section on

P48:

Linearization table

(See Figure 19) Linearization is the method of assigning requested (calibrated or calculated) level, volume or flow to values measured by the smart transmitter.

It can be used, as an example, if the sound velocity is not known (LEVEL

⇒LEVEL) or in the case of vertical cylindrical tank (LEVEL

⇒VOLUME) etc. Data-pairs of the

Linearization table are handled in a 2x32 matrix, consisting of two columns.

LEFT COLUMN “L”

Measured LEVEL

RIGHT COLUMN “r”

Calibrated LEVEL, VOLUME or FLOW

The left column values (indicated on the display as “

L”) contain the measured LEVEL values. The right column values (indicated on the display as “ r”) contain the calibrated values and are interpreted according to the selected measurement value in

P01(a).

Conditions of correct programming of the data pairs:

LEFT COLUMN “L”

L(1)= 0

L(i)

:

L(j)

RIGHT COLUMN “r”

r(1) r(i)

: r(j)

1) The table must always start with: L(1)= 0 and r(1)= value (assigned to 0 level).

Figure 19

22

2) The table must be ended either with the 32nd data pair, i.e. j=32, or if the linearization table contains less than

32 data-pairs, j<32, the table must be closed by a level value “0”, e.g. L (j<32) = 0.

3) The transmitter will ignore data after recognizing the level value “0” with serial number other than “1”.

parameter, echo monitoring will freeze and the number, distance and amplitude of the last recorded echoes can be viewed.

If the above conditions are not met, error codes will be displayed (See Error Codes on page 24).

The purpose of this feature is to provide protection against accidental (or intentional) re-programming of parameters.

P81:---a

Relay test (4-wire units only)

The actual state of the relay can be seen on the display

(code according to the table below and symbol on the screen). Test the relay by pressing UP and DOWN while observing change of the symbol and the code or listening to the ticking of the relay or checking on-off resistance by a suitable resistance meter.

The Secret Code (password) can be a numeric value other than 0000. Setting a Secret Code will automatically be activated when the smart transmitter is returned to the Measurement Mode. If the Secret Code is activated, the parameters can only be viewed, this is indicated by the flashing colon “:” between the parameter address and the parameter value.

In order to program the device locked by a secret code, first enter the Secret Code in P99. The Secret Code is reactivated each time the smart transmitter is returned to

Measurement Mode.

To delete the Secret Code, enter the Secret Code in P99.

After confirming it with

[E], re-enter the parameter P99 and enter

0000.

PROBLEM: The display is completely blank, or will not display a measurement.

CAUSE/SOLUTION:

1) Verify electrical power is connected to proper terminations and that it is the proper voltage depicted on the smart transmitter label.

PROBLEM: The distance (DIS) display does not vary and is reading a distance other than that of the material surface.

CAUSE/SOLUTION:

1) The echo being measured is from an internal obstruction, or is a “double echo” from a nearby internal obstruction.

25

2) Re-aim the smart transmitter away from the obstruction.

3) Block the obstruction out using parameters P29 and/or

P30 (See Parameter section). If the false echo is a double echo, however, you may not be able to block it out. Re-aim the smart transmitter.

4) Use the Echo Map parameter P70 to locate all echoes and their corresponding amplitudes.

5) Unit may require power-down to re-boot.

PROBLEM: The measurement stops (goes into an error mode) during filling operation.

CAUSE/SOLUTION:

1) Airborne dust and/or falling material is interfering with the measurement.

2) Re-aim the smart transmitter away from incoming material.

PROBLEM: The DIS measurement is twice that of the expected value.

CAUSE/SOLUTION:

1) The material level has entered the dead-band of the smart transmitter and is locking on to the second reflection coming from the material surface.

2) Make sure the material does not exceed the level corresponding to the dead-band of the smart transmitter

(See P05 in Parameter section).

PROBLEM: The DIS measurement does vary, but is longer than that of the expected value.

CAUSE/SOLUTION:

1) This may be a “ring-out”, caused by mechanical resonance if the smart transmitter is not secured firmly enough. Verify the transmitter mounting.

2) The echo may also be reflecting off a flat material surface, then off the silo wall, then back to the transmitter.

Re-aim the smart transmitter.

M A I N T E N A N C E

Smart transmitters may require occasional cleaning in applications involving adhesive or sticky materials that may contact the sensor surface. The maintenance consists of a visual inspection of the sensor surface and cleaning whenever necessary. While in operation, the sensor face is vibrating which has a self-cleaning effect. If the material is not sticky, no cleaning is required.
