With a stainless steel float and float rod, these gauges resist corroding from chemicals. Their indicator moves up as your tank fills. Check the indicator against the graduation marks to see how full your tank is and if you need to fill or drain it. Plastic protects the indicator's movement, saving you from inaccurate readings.

Alarms can be set to flash and sound at levels critical to your system.

Remote-reading displays let you check readings from up to 100 ft. away. They have an alarm that sounds when the level is too high or too low.

Install these gauges through the top of your tank to monitor diesel fuel, fuel oil, or gasoline level.

Gauges with float rods are UL Listed for flammable liquids. For shallower tanks, cut the float rod ½” to 1” shorter than your tank depth to prevent it from touching the bottom.

Optional remote-reading dials use two wires to send a signal to a receiver or dashboard for monitoring fuel levels remotely.

For precise measurement of water, hydraulic fluid, or diesel fuel level, this gauge provides level readings down to 1/8". The small hand on the dial displays feet, and the large hand displays inches. It comes with decals to mark high and low levels.
