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.

Horizontal-mount gauges install by attaching one pipe connection to the opening of a horizontal drum. Attach a drain or valve to the pipe connection on the other end. They have sliding markers for calibration and 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.
