EFG-8000 Tank Information


Typically, all Solar Gauge products have been per-calibrated by the manufacturer. These calibrations are based on the following information: Size and dimensions of the tank, actual tank capacity, type of liquid to be measured, the desired high level over fill alarm value, low level warning alarm value, and the off-set value to compensate for the unusable fuel to be left in the tank. These calibrations can also be easily accomplished by the operator in the field if necessary.


As liquid is added to, or removed from the tank, the changing buoyancy of the probe reflects the changing volume in the tank via the digital display. The gauge can be easily calibrated to read out in gallons, liters, pounds, inches, or % of tank full. Being solar powered, the gauge requires no external supply voltage.


Probes are custom manufactured according to the tank height and type of liquid to be measured. Please supply us with:

  1. Actual tank capacity,
  2. Type of liquid to be measured,
  3. Height of the tank,
  4. Total distance from the top of the 2" NPT pipe nipple to the bottom of the tank. For the best performance, we recommend a minimum 6" long pipe nipple.
