2) incorrect installation (placing the unit diagonally, Empty test – ON)
Installation in piping and placement of measuring electrodes in flow sensor
1) in the version without the earthed reference electrode and/or empty piping test (2 electrodes)
2) in the version with earthed electrode and/or empty piping test electrode (3/4 of the electrode)
During installation, beware of:
- dropping the meter onto the ground and damaging the measuring tube or electronics
- contamination of the electrodes (do not touch the electrodes, otherwise they get
contaminated)
- when additional sealing is used, avoid its interference in the flow profile of the detector
between the flanges and the pipeline, otherwise the flow measurement error may be
increased
Tightening torques
It is absolutely necessary to tighten the bolts and nuts equally by alternating sides and in the order
shown in figure applying the maximum torque according to the table.
