Endress+Hauser Waterpilot FMX21 - Configuring Pressure Measurement; Configuring the Damping

Waterpilot FMX21 Commissioning

Description Position adjustment – the pressure difference between zero (set point) and the measured
pressure must be known.
Options • Confirm
• Cancel
Example • Measured value = 982.2 mbar (15 psi)
• You correct the measured value via the "Calib. offset" parameter with the "Confirm"
option. i.e. This means that you are assigning the value 980.0 to the pressure present.
• Measured value (after position adjustment) = 980 mbar (15 psi)
• The current value is also corrected.
Factory setting Cancel
9.8 Configuring the damping
The pressure resulting from the orientation of the device can be corrected here.
Damping
Navigation Setup → Damping

(if the "Damping" DIP switch is set to "on")
Description
Enter damping time (time constant t) ("Damping" DIP switch set to "on")
Display damping time (time constant t) ("Damping" DIP switch set to "off").
The damping affects the speed at which the measured value reacts to changes in pressure.
Input range 0.0 to 999.0 s
Factory setting 2.0 sec. or according to order specifications
9.9 Configuring pressure measurement
9.9.1 Calibration with reference pressure (wet calibration)
Example:
In this example, a device with a 400 mbar (6 psi) sensor module is configured for the
0 to +300 mbar (0 to 4.5 psi) measuring range i.e. 0 mbar is assigned to the 4 mA value
and 300 mbar (4.5 psi) is assigned to the 20 mA value.
