Water tank gauges for boat fuel tanks, designed to measure water tank level, available from Faria Beede and Vetus. These water tank level indicator gauges use European or American resistance senders to give a visual display of water level to a gauge mounted in the boat dashboard. The senders work by measuring the resistance in the tank and converting that to a level, displaying empty to full.
All Faria gauges within this section measure 2 inches in diameter.
Choosing between European and American resistance:A water level sender uses resistance to operate the water level gauge. The sender supplies the gauge with a resistance which the gauge then displays as a reading on the dial, but this can be either European or American resistance. A European resistance water level sender has a low output at empty and as the water level increases so will the resistance, while an American resistance water sender will have a high output at empty and the resistance will decrease as the water level increases. It is important to match the gauge with the correct sender, as a mix of European and American resistance will lead your gauge to read backwards!
