Electronic Register & Level Gauge

Liquip have uniquely developed the DFV series which has become the most technically advanced Register and Diptronic unit avaliable on the market.

Avaliable as a standalone Register, Diptronic CPU or combined unit, the DFV combines long service life with simple operation and reliablity.

The DFV is a lightweight unit and is approved for use in Zone 1 hazardous areas (IECEx & ATEX) truck mounted or fixed site product transfer applications.



  • Safety Approved for use in Zone 1 locations.
  • Weights & Measures Approved: Australia, Europe (MID), New Zealand.
  • Large display to easily view multiple information simultaneously.
  • RS232 and CAN communication.
  • Intuitive set up and programming.
  • Can be connected to a large digit display.
  • For full features download the DFV101 datasheet.


  • Preset functionality / batch control.
  • Solenoid outputs are voltage free and can perform a 2 stage ramp up and ramp down.
  • For full features download the DFV100 Datasheet.


  • ±1mm accuracy.
  • Automatic level gauging updated in real time to reduce delivery times.
  • Eye level display of compartment volume to keep operators off the top of the tank and removing the need for ladders and hand rails.
  • Can read up to 9 probes/compartments.
  • Comes with built in power filter.
  • Volume shown in 1L increments.
  • Temperature compensated deliveries.
  • Enables split deliveries to maximise fleet utlisation and efficiency.
  • For full features download the DFV103 datasheet.
