5250 Deck Gauge
The 5250 Deck Gauge provides an accurate and clear display of the tank level right at the point of filling. It is designed to be installed near to the tank filler to help avoid refuelling spills and prevent water pollution incidents.
It has a clear blue LED digital display that automatically dims at night to preserve night vision mounted in an attractive stainless steel bezel that is easy to install.

3271 Fuel Level Sender
The 3271 Volumetric Fuel Sender provides very accurate measurement and output of either the remaining Fuel LEVEL or the remaining Fuel VOLUME to the NMEA2000 network.
It is accurate to ±2% and automatically provides a stilling action to dampen out fuel slosh in the tank to maximise accuracy when conditions are rough or the boat is travelling quickly.
The 3271 can be programmed with up to 100 volumetric points, so that it offers the most accurate indication of the remaining VOLUME of fuel in the tank. This volume information can then be displayed on any NMEA2000® enabled display, wherever it is required.

3281 Water Level Sender
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.
They are robustly constructed in stainless steel with no moving parts to stick or fail in service. They are easily cut to length to suit tank depths from 250mm to 2 metres.

4620-4626 GENERAL PURPOSE 4-20MA PRESSURE SENSORS
