Water and fuel tank sensors — correct length depending on tank depth

In the Water and Fuel Tank Sensors product group, you will find Weman S5 series tank sensors in five different lengths — 200 mm, 250 mm, 300 mm, 350 mm and 500 mm — as well as Weman VDO compatible fuel tank sensor. Unlike the gauge itself (see our Fuel Gauges product group), the sensor is the part that is physically installed inside the tank and measures the height of the liquid surface using a float ball — the gauge simply displays the signal sent by the sensor in the cockpit.

The length of the sensor should be chosen carefully according to the depth of the tank: a sensor that is too short will not reach the bottom of the tank and will falsely show an empty tank as partially full, while a sensor that is too long may hit the bottom of the tank and be damaged or give an incorrect reading even when the tank is full. Always measure the actual internal depth of the tank carefully before ordering — the 200-500 mm range covers most boat tank sizes from small auxiliary tanks to larger main tanks.

The S5 series sensors are suitable for both fuel and water tanks, making the range flexible regardless of whether you are measuring diesel, gasoline or drinking water - the same sensor model works for both applications when installed correctly.

Remember that the sensor should always be replaced with a compatible gauge to ensure the correct resistance value, and it is recommended to use a gasket suitable for the tank material during installation to avoid leaks — special care is required when installing a fuel tank sensor for safety reasons.

The sensor is usually mounted vertically on the top surface of the tank, and the float ball must be able to move unhindered the entire measured distance from the bottom of the tank to almost the top edge — before installation, check that there are no stiffeners or other structures inside the tank in the path of the float ball, as an obstruction along the way will cause an incorrect or completely stuck reading. When installing a fuel tank sensor, it is also important to use explosion-proof tools and ensure that there are no residual gases in the tank before opening the lid.
