electrical connections
1. Ensure that the fl ow sensor frame is connected to ground (
⏚)
; it is recommended that the ground
terminal at the outside of the sensor is used for this purpose. This will prevent against undesirable
interference, particularly for detached versions when shielding the link cable between the sensor
and electronic unit while connected to the frame.
Remove the upper cover of the instrument to gain access to terminals for the power cable and
the signal cables.
