For use with water, hydraulic fluid, and diesel fuel, install these gauges through the top of your tank. All have an indicator that moves up as the tank fills. To see how full your tank is and if you need to fill or drain it, check the indicator against the graduation marks. 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.

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.

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.

More than twice as accurate as standard totalizers for fuel, these measure the total flow volume of gasoline, diesel fuel, and kerosene with ±2% accuracy. They display a resettable batch total volume to keep track of one metering application and a nonresettable total flow volume. The mesh strainer traps debris.

Measure the total flow volume of gasoline, diesel fuel, and kerosene. These totalizers automatically reset to zero when they reach the maximum reading.
