The 3281 NMEA2000 Universal Water Tank Sender will provide a ±2% accurate level in either a Fresh, Grey or Black water tank to the NMEA2000 marine network and reports it's level in 1% increments.

It is robustly constructed in stainless steel with no moving parts to stick or fail in service. It is easily cut to length to suit tank depths from 200mm to 2 metres and is self calibrating at power on.

The Tank Level Sender can store an alphanumeric Tank Name and Tank Shape Calibration data so that displays on the network can show the tank name and it's remaining capacity in Litres, US Gallons or in Gallons.

It is easily fitted in the water tank into a 1.25" BSP threaded hole. It can also be attached to the industry standard SAE 5 bolt fitting by using the optional 5 Bolt to 1.25" BSP Mounting Ring part number 3261.
