3.1 Product design

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

A0016449

1 Sensor module LP 2 Sensor module HP 3 Transmitter

The FMD71/FMD72 is best suited to level measurement in tanks with pressure overlay or 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.

Product description Deltabar FMD71, FMD72

3.2 Function

3.2.1 Differential pressure generation

The measurement chain for the calculation of the differential pressure can be represented by the following diagram:

LP 

HP 

Sensor press.

 

Sensor

calibration LP

Sensor

calibration HP

 

Sensor press.

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 "Connect transm. (286)" parameter .

6.6 Installing the sensor modules

6.6.1 General installation instructions

• The nameplate on the sensor module specifies where the sensor module is typically installed: HP (bottom) LP (top) For further information, see the "Function" (  12) section.

• 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 "Commissioning without an operating menu" (  42) or the "Position adjustment" section(  47) .

• 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 corresponding 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.

Operation with an operating menu Deltabar FMD71, FMD72

9 Operation with an operating menu

9.1 Operating concept

Operation with an operating menu is based on an operation concept with "user roles" .

User role Meaning

Operator Operators are responsible for the devices during normal "operation". This is usually limited to

reading process values either directly at the device or in a control room. If the work with the devices goes beyond reading, it concerns simple, application-specific functions that are used in operation. Should an error occur, these users simple forward the information on the errors but do not intervene themselves.

Maintenance Service engineers usually work with the devices in the phases following device commissioning.

They are primarily involved in maintenance and troubleshooting activities for which simple settings have to be made at the device. Technicians work with the devices over the entire life cycle of the product. Thus, commissioning and advanced settings and configurations are some of the tasks they have to carry out.

Expert Experts work with the devices over the entire life cycle of the device, but, in part, have high

requirements on the devices. Individual parameters/functions from the overall functionality of the devices are required for this purpose time and again. In addition to technical, processoriented tasks, experts can also perform administrative tasks (e.g. user administration). "Experts" can avail of the entire parameter set.

9.2 Structure of the operating menu

User role Submenu Meaning/use

Operator Language Only consists of the "Language" parameter (000) where the operating language

for the device is specified. The language can always be changed even if the device is locked.

Display/ operat.

Maintenance Setup Contains all the parameters that are needed to commission measuring operations.

Contains parameters that are needed to configure the measured value display (selecting the values displayed, display format, etc.). With this submenu, users can change the measured value display without affecting the actual measurement.

This submenu has the following structure:

• Standard setup parameters A wide range of parameters, which can be used to configure a typical application, is available at the start. The measuring mode selected determines which parameters are available. After making settings for all these parameters, the measuring operation should be completely configured in the majority of cases.

• "Extended Setup" submenu The "Extended Setup" submenu contains additional parameters for more indepth configuration of the measurement operation to convert the measured value and to scale the output signal. This menu is split into additional submenus depending on the measuring mode selected.

Deltabar FMD71, FMD72 Operation with an operating menu

User role Submenu Meaning/use

Diagnostics Contains all the parameters that are needed to detect and analyze operating

errors. This submenu has the following structure:

• Diagnostic list Contains up to 10 currently pending error messages.

• Event logbook Contains the last 10 error messages (no longer pending).

• Instrument info Contains information for identifying the device.

• Measured values Contains all current measured values.

• Simulation Is used to simulate pressure, level, flow, current and alarm/warning.

• Reset

• Sensor LP

• Sensor HP

Expert Expert Contains all the parameters of the device (including those already in one of the

submenus). The "Expert" submenu is structured by the function blocks of the device. It thus contains the following submenus:

• System Contains all device parameters that neither affect measurement nor integration into a distributed control system.

• Measurement Contains all parameters for configuring the measurement.

• Output Contains all parameters for configuring the current output.

• Communication Contains all parameters for configuring the HART interface.

• Diagnostics Contains all the parameters that are needed to detect and analyze operating errors.

9.4 Operating the device using onsite display (optional)

A 4-line liquid crystal display (LCD) is used for display and operation. The onsite display shows measured values, dialog text as well as fault and notice messages in plain text, thereby supporting the user in every stage of operation. The device display can be turned in 90° steps. Depending on the installation position of the device, this makes it easy to operate the device and read the measured value.

11.7.1 Information on level measurement

You have a choice of two methods for calculating the level: "In pressure" and "In height". The table in the "Overview of level measurement" section that follows provides you with an overview of these two measuring tasks.

• The limit values are not checked, i.e. the values entered must be appropriate for the sensor module and the measuring task for the device to be able to measure correctly.

• Customer-specific units are not possible.

• There is no unit conversion.

• The values entered for "Empty Calib./Full Calib.", "Empty Pressure/Full Pressure", "Empty Height/Full Height", and "Set LRV/Set URV" must be at least 1% apart. The value will be rejected, and a warning message displayed, if the values are too close together.

11.7.3 "In pressure" level selection Calibration with reference pressure (wet calibration)

Example:

In this example, the level in a tank should be measured in "m". The maximum level is 3 m (9.8 ft). The pressure range is derived from the level and the density of the medium. In this situation, the device sets the pressure range to 0 to 300 mbar (4.5 psi).

Prerequisite:

• The measured variable is in direct proportion to the pressure.

• The tank can be filled and emptied.

The values entered for "Empty Calib./Full Calib.", "Set LRV/Set URV", and the applied pressures must be at least 1% apart. The value will be rejected, and a warning message displayed, if the values are too close together. Further limit values are not checked, i.e. the values entered must be appropriate for the sensor module and the measuring task for the device to be able to measure correctly.

11.9 Configuring pressure measurement

11.9.1 Calibration without reference pressure (dry calibration)

Example:

In this example, a device with a 400 mbar (6 psi) sensor module is configured for the 0 to +300 mbar (4.4 psi) measuring range, i.e. the 4 mA value and the 20 mA value are assigned 0 mbar and 300 mbar (4.4 psi) respectively.

Prerequisite:

This is a theoretical calibration, i.e. the pressure values for the lower and upper range are known. It is not necessary to apply pressure.

Due to the orientation of the device, there may be pressure shifts in the measured value, i.e. the measured value is not zero in a pressureless condition. For information on how to perform position adjustment, see Pos. Zero Adjust(  47) section.

Enter and confirm the value (here 0 mbar (0 psi)) for the "Set LRV" parameter. This pressure value is assigned to the lower current value (4 mA).

4 Select the "Set URV (014)" parameter.

Menu path: Setup  Set URV

Enter and confirm the value (here 300 mbar (4.5 psi)) for the "Set URV (014)" parameter. This pressure value is assigned to the upper current value (20 mA).
