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 center shafts should reach ½” to 1” above the bottom of your tank to prevent it from touching the bottom.

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 dials with output show fuel level at the source or use the two wires to connect them to monitors, dashboards, or other receivers for remote monitoring. They are also known as fuel senders.

Mount these gauges on the flat end of a horizontal, cylindrical tank to monitor diesel fuel, fuel oil, or gasoline level. They are UL listed for flammable liquids. For shallower tanks, cut the rod ½” to 1” shorter than your tank depth to prevent it from touching the bottom.

Using inches or centimeters instead of common levels, such as full or empty, these gauges are more precise than standard gauges when measuring liquid levels. While most gauges are designed for one tank depth, these have a float attached to a cable, so they work with any tank up to the maximum depth listed.

Style A gauges come with labels, so you can record the measurements that correspond to common levels such as full, 1/2, and empty.

Style B gauges have a dial with a small hand that displays feet and a large hand that displays inches. They come with labels to mark high and low levels on the dial face.

Measure water, hydraulic fluid, or diesel fuel level in your drum.

Gauges with 316 stainless steel float rods are more corrosion resistant than gauges with zinc-plated steel float rods.

Vertical-mount gauges install through the top opening of your drum. Their indicator moves up as your drum fills. Check the indicator against the graduation marks to see how full your drum is and if you need to fill or drain it. Plastic protects the indicator's movement, saving you from inaccurate readings. These gauges also measure your liquid in gallons and liters.

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.
