S5E FUEL/WATER TANK SENDER UNITS Wema-System is a manufacturer of high quality, heavy duty, tank level sending units for a variety of marine applications. The S5 series sender is an innovative solution for monitoring the level of fuel and/or water tanks in boats, trucks, coaches, caravans and recreational vehicles. 

Superior to conventional float arm type senders, the Wema-System solution for monitoring fuel and/or water tank levels is presented in the S5 model tubular sender unit. 

With the float as the only moving external part the S5 sender is designed with longevity, durability and performance in mind. Constructed in AISI 316 stainless steel the sender is suitable for a wide range of mediums including, diesel, petrol, fuel oil, potable and grey water. The sender incorporates an industry standard 5 hole mounting flange which is compatible with other SAE standard bolt patterns. An underside (in tank) mounting flange is available when the sender is to be installed in thin walled tanks. 

The S5 sender is available in a multitude of lengths to suit tanks from 150 millimetres up to 1.5 metres in depth. Termination is via flying leads which have a sealed entry into the top of the sender for water resistance. 

A range of matching Wema-System gauges is readily available for the S5 series tank sender units. The S5E range suits our range of Wema gauges or other "European" spec gauges that work in the 0 (empty) to 180 (full) Ohm range. 

*Please note: Longer length senders are available upon request. Just contact us via email or phone with your requirements!
