Our clock mechanical sensors have been designed to measure practically all fuel types in both underground and above ground tanks, providing a very accurate mechanical indication without the need for electrical supply. They're easy to install - with a single pointer - making them extremely flexible. The clock mechanical sensors are available in varying lengths to accommodate most tank configurations.
The ProGauge O-RANGE model offers a maximum probe shaft length of 3 metres, has a single display needle and 10mm resolution.
The ProGauge LeMon is designed for measuring tanks with a depth up to and including 5 metres, has 2 display needles and a resolution of 5mm.
