Zero point adjustment
The flowmeter system is optimized through a zero point adjustment.
Performing a zero point adjustment
CAUTION
Gas application
Zero point adjusting the device is only recommended for liquid applications.
1. Flush out any gases and obtain stable temperature conditions by running flow at operational
conditions (pressure and temperature) for minimum 30 minutes.
Figure 6-2
Best practice zero point adjustment with a by-pass line and two shut-off devices
2. Close the outlet shut-off valve while maintaining the system pressure. If bypass flow is
necessary, open the bypass valve. If the pressure can be increased by 1 to 2 bars with
stopped flow, this should be applied.
3. Wait 1 to 2 minutes, for the system to settle, and then perform zero adjustment. Waiting
longer can change the temperature.
