5.4 Flow Cell Pressure Sensor (Optional)
As an optional feature the UFM can be equipped with a pressure sensor.
This pressure sensor is used for:
 Reynolds flow profile correction
 Compensation of the flow cell expansion due to gas pressure.
5.5 Flow Cell Temperature Sensor
The UFM is equipped with a temperature sensor. The temperature sensor is
used for:
 The Reynolds flow profile correction
 Compensation of the flow cell expansion due to flow cell
temperature
CAUTION!
The pressure sensor is not used for volume conversion.
