Level Sensor Assemblies

 

Liquip offers a range of level sensor (Diptronic) assemblies for measuring the compartment contents on road tankers. Power to the level sensor and readout of the compartment contents is provided by the Liquip CPU models: DFV103, DFV101 or DFV101S CPU monitor.


Level sensor assemblies provide an accurate measure of compartment contents in real time and eliminate the need for manual dipsticks resulting in improved operator safety as the need to climb on top of tanks to check compartment levels is removed. Release of harmful VOCs is also reduced as opening of compartment access fittings is no longer required.

Features & Benefits
  • Radar transmitters ensures high tech  and accurate measuring of tanker contents.
  • Measurement and eye-level display of all compartment contents in litres.
  • No need for operators to climb on top of tanks to measure hazardous substances.
  • Length and range of the sensors can be made to suit height of the compartment on order.
  • +/- 1mm accuracy.
  • Can suit walkway or hatch mount applications.
  • No Moving Parts and one-time calibration.

Technical Information

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. 

Materials
Aluminium cover and base
