 2 Correlation between slope of electrode and flow velocity at the membrane/volume flow in
assembly
At higher flow rates, the measured signal is virtually flow-independent. However, if the flow
rate falls below the specified value, the measured signal depends on the flow.
Temperature
Changes in the temperature of the medium affect the measured value:
• Increases in temperature result in a higher measured value (approx. 4 % per K)
• Decreases in temperature result in a lower measured value.
Use of the sensor in combination with the Liquiline enables automatic temperature
compensation (ATC). Recalibration in the case of temperature changes is not necessary.
1. If automatic temperature compensation is disabled at the transmitter, the temperature
must be maintained at a constant level following calibration.
2. Otherwise, recalibrate the sensor.
In the event of normal and slow changes in temperature (0.3 K / minute), the internal
temperature sensor is sufficient. In the event of very rapid temperature fluctuations with high
amplitude (2 K / minute), an external temperature sensor is necessary to ensure maximum
accuracy.
