The 3281-500 Water Level Sender – Probe Length 500mm

For fresh water tanks

The 3281 Water Level Sender will measure the water level in the fresh water tanks. They provide a ±2% accurate tank level to the NMEA2000® marine network.

The 3281 can be programmed with up to 100 volumetric points so that it offers the most accurate indication of the VOLUME of water in the tank. This volume information can then be displayed on any NMEA2000® enabled display wherever it is required.

It is robustly constructed in stainless steel with no moving parts to stick or fail in service. It is available to suit tank depths from 250mm to 2 metres.

Up to 16 senders can be connected to a single network and the tank number is simply selectable at installation by means of the small rotary switch.

It is manufactured to the NMEA2000® network standard and attaches to the network using a single “Micro” plug. It draws less than 50mA from the network.
