Wire adjustment—Wire sensor
The sensor is installed in the standpipe or directly in the tank. The sensor length is determined by standpipe length or tank
height. Cut the insulated steel wire to desired length with a wire cutters or bolt cutter in the end where the weight is in-
stalled. The weight is fixed by the 2 screws. Liquid sealant is applied to the thread.
When sealing the conical thread, you must use liquid conductive sealant, which creates
a ground connection between the standpipe/tank and the sensor, since the sensor uses
the standpipe/tank as reference. If Teflon is used, it must only be used on part of the
thread so that the ground connection is established. If you are in doubt regarding the
ground connection, measuring the resistance between the tank and sensor is recom-
mended. This should be approx. 0 ohms.
An aluminum sealing/washer has been included for the sensor with cylindrical thread.
