Wema Fuel/Water Tank Level Sender Threaded 0-190 Ohms

$107.00
Description

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 is 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. It 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. Made from non-corrosive materials to withstand harsh environments, WEMA takes an uncompromising stance on quality; their level sensors meet all applicable ISO, CE, NMMA, ABYC and USCG standards. Rated 0-190 Ohm — you must match the same Ohms rated senders with gauges.

FAQ's


Q: Can I use this sender with a black water tank?

A: No, it's not rated for black water use.

Q: What happens if I mismatch the Ohm rating?

A: Your fuel or water gauge will display incorrect readings.

Q: How do I test if it’s working?

A: Connect to a multimeter and move the float—resistance should range from 0 Ohm (empty) to 190 Ohm (full).
