Cerabar PMP71B HART Commissioning
Hauser 45
Prerequisites:
• Measured variable in direct proportion to the pressure
• Due to the orientation of the measuring device, there may be pressure shifts in the
measured value (when the vessel is empty or partly filled, the measured value is not
zero)
Perform position adjustment if necessary

A "Pressure value 1" parameter and "Scaled variable value 1" parameter
B "Pressure value 2" parameter and "Scaled variable value 2" parameter
The pressure present is displayed in the operating tool on the same settings page in
the "Pressure" field.
1. Enter the pressure value for the lower calibration point via the Pressure value 1
parameter: 50 mbar (0.75 psi)
 Menu path: Application → Sensor → Scaled variable → Pressure value 1
2. Enter the volume value for the lower calibration point via the Scaled variable value
1 parameter: 0 l (0 gal)
 Menu path: Application → Sensor → Scaled variable → Scaled variable value 1
3. Enter the pressure value for the upper calibration point via the Pressure value 2
parameter: 450 mbar (6.75 psi)
 Menu path: Application → Sensor → Scaled variable → Pressure value 2
4. Enter the volume value for the upper calibration point via the Scaled variable value
2 parameter: 1 000 l (264 gal)
 Menu path: Application → Sensor → Scaled variable → Scaled variable value 2
Result: The measuring range is set for 0 to 1 000 l (0 to 264 gal). Only the Scaled variable
value 1 parameter and Scaled variable value 2 parameter are set with this setting. This
setting has no effect on the current output.
