This sender is constructed to meet and/or exceed all applicable ISO, NMMA/ABYC and USCG standards. Easy to install, the fuel/water sender uses the SAE 5 hole pattern; constructed of 316 stainless steel and fully insulated to protect against voltage inside the tank. The float is the only moving part of the sensor minimizing mechanical failure. Best of all, there is no calibration required.

How It Works
Measurement is achieved by a series of reed switches positioned inside the level tube. The float with built in magnets then triggers the reed relays generating a potential - free resistance with an ohm value that increases or decreases.

Livorsi carries 240-33 OHMS in stock. Other resistance outputs or senders with a 1 1/4"or 1 1/2" NPT are available upon request.
The sending unit length should be a minimum of one (1) inch less than the depth of the tank.
