【Migration Volume】Differential Pressure Transmitter

Thread Content

Is the migration amount of the differential pressure transmitter calculated as “pressure on the negative pressure side” minus “pressure on the positive pressure side” when there is no liquid level? Move this value to 0? How is the ZERO ZEV % value calculated on the BT200 controller?

The migration amount is the differential pressure generated by the transmitter at the start of the measurement lower limit, which is removed through migration.

The migration amount is positive pressure compression minus negative pressure compression. Then set this value to zero.
