Sensor Offset

3.7.6 Level Configuration

Sensor Offset must be applied in cases where:

• A Volume Output is required and the Sensor Mounting Reference

extends below the top of the tank or, the Sensor Mounting Reference

is mounted above the top of the tank.

See Figure 3.7-7

• If the Sensor Mounting Reference is mounted above the top of the

vessel, a positive value is entered in Sensor Offset .

• If the Sensor Mounting Reference is mounted below the top of the

tank, a negative value is entered in
