Weight Calibration for NMS with Guide Wire
Weight Calibration Procedure
1.
Fix NMS5 temporarily so that NMS5 is located at the outside the reducer plate to perform weight
calibration.
2.
Replace the measuring wire to an appropriate length.
•
During standard weight calibration, the displacer moves up until it touches the mechanical stop in the
housing.
•
After weight calibration is finished, the displacer stops 70mm (the value set in the matrix (configurable,
GVH378)) below the mechanical stop. This is the Reference Position.
3.
During this special weight calibration, the guide rings of the displacer touches the bottom face of the
flange.
4.
The displacer goes down 70mm and stops. NMS5 remembers the distance of 70mm as Reference
Position, and weight table calibration resumes.
5.
When weight calibration is complete, return NMS5 back to its original mounting position on the tank
nozzle.
This completes the weight calibration procedure.
