Operation
The level sensor is mounted to the walkway or manhole cover on top of the tank with the shaft and tube extending to the bottom of the tank, in most cases. The tube is held in place at the bottom of the tank by means of a weld in tube steady, also supplied by Liquip. Power to the sensor and readout of the levels are provided by Liquip’s DFV series CPUs.
Dismantle
Remove 4 off M5 hex screw to open the cover and access PCB assembly and sensor. (Note: These screws are to be lead sealed after calibration).
Adjustment
Refer to instruction manuals 7331 & 7326 for setup and calibration of the system with DIP2xx CPUs.
Refer to instruction manuals 7403 for setup and calibration of the system with DFV1xx CPUs.
