3.1 Product design

Level measurement (level, volume and mass) with Deltabar:

A0016449

LP Sensor module LP (low pressure) HP Sensor module HP (high pressure) p2 Head pressure p1 Hydrostatic pressure 1 Transmitter

The FMD71/FMD72 is best suited to level measurement in vessels with pressure overlay or in vacuum vessels and tanks, high distillation columns and other vessels with changing ambient temperatures.

The sensor module HP is mounted on the lower measuring connection and the sensor module LP is mounted above the maximum level. The transmitter can be mounted on pipes or walls with the mounting bracket.

The sensor signal is transmitted digitally. In addition, sensor temperatures and the individual process pressures present at the respective sensor modules can be individually evaluated and transmitted.

NOTICE

Incorrect sizing/order of sensor modules

In a closed system, please note that the sensor module is affected by the superimposed

‣

head pressure (p2) in addition to the hydrostatic pressure (p1). This must be taken into account when sizing the sensor module on the high-pressure side (HP).

Sensor

pressure HP

Sensor trim LP

All the process values represented on the diagram are updated in a measurement cycle. The sensor module allocation is determined by the configuration when setting up the device. The connection to the transmitter defines the corresponding sensor module as the master. After commissioning, the second sensor module is detected as the slave. This configuration can be modified as desired. However, a modification must take place with the unit disconnected from the power supply.

The sensor modules have a designation independent of the master/slave configuration. This indicates where the sensor module is typically installed:

• Sensor module LP

LP = Low pressure; top

• Sensor module HP

HP = High pressure; bottom

For identical sensor module ranges, this assignment can likewise be changed, but this then has to be configured in the menu.

If you change both sensor modules or the electronics, this allocation must likewise be carried out. See the "Transm. connect. (286)" parameter .

• The nameplate on the sensor module specifies where the sensor module is typically installed: HP (bottom) LP (top) For further information, see the "Function" section →  13.

• Due to the orientation of the sensor modules, there may be a shift in the zero point, i.e. when the vessel is empty or partially full, the measured value does not display zero. You can correct this zero point shift: see the "Commissioning without an operating menu" →  42or the "Position adjustment"→  47 section.

• Always install the sensor module HP below the lowest measuring point.

• Always install the sensor module LP above the highest measuring point.

• Do not mount the sensor modules in the filling curtain or at a point in the tank which could be affected by pressure pulses from an agitator.

• Do not mount the sensor modules in the suction area of a pump.

• The adjustment and functional test can be carried out more easily if you mount the sensor modules downstream of a shutoff device.

• If a heated sensor module is cooled during the cleaning process (e.g. by cold water), a vacuum develops for a short time, whereby moisture can penetrate the sensor through the pressure compensation (3). If this is the case, mount the sensor with the pressure compensation (3) pointing downwards.

• Keep the pressure compensation and GORE-TEX® filter (3) free from contamination.

• Do not clean or touch process isolating diaphragms with hard or pointed objects.

Measuring a 4 to 20 mA test signal

A 4 to 20 mA test signal may be measured via the positive and test terminal without interrupting the measurement. The minimum supply voltage of the device can be reduced by simply changing the position of the jumper. As a result, operation is also possible with a lower supply voltage. To keep the measured error below 0.1 %, the current measuring device should exhibit an internal resistance of <0.7Ω. Observe the position of the jumper in accordance with the following table.

Jumper position for test signal

Description

• Measurement of 4 to 20 mA test signal via the positive and test terminal: possible. (Thus, the output current can be measured without interruption via the diode.)
