The SeeLeveL provides a digital readout of tank level with better than 3% accuracy - no more 1/3 - 2/3 - Full.

The SeeLeveL sensor is located on the outside of the holding tank, so it cannot be compromised by tank contents.

Through the use of PhaseFour electronic valves, emptying of tanks is controlled by the push of a button.

Patent Pending automated system replaces 40 year old technology - it truly is "a better mouse trap"!
