The S3 sender is an innovative solution for monitoring the level of fuel and/or water tanks in boats, trucks, coaches, caravans and recreational vehicles.
With the float as the only moving external part, the S3 designed with longevity, durability and performance in mind.
Constructed in AISI 316 stainless steel it's suitable for a wide range of mediums including, diesel, petrol, oil, potable and grey water.
Mounts via a 1 1/4" BSP (British Standard Pipe Parallel) fitting and can be simply screwed into the top of a matching tank. The connection cable has a sealed entry into the top of the sender for water resistance.
Non corrosive materials in order to withstand the rigors of their operating environment. We take an uncompromising stance on quality; therefore, our level sensors are constructed to meet all applicable ISO, CE, NMMA, ABYC and USCG standards.
To test operation, unscrew the fuel sender, connect two wires to a multimeter, set to resistance and move the float up and down by hand.
A-Sensor: With the float at the bottom it should read 240 ohm and at the top 30 ohm.
