For use with water, hydraulic fluid, and diesel, install these gauges through the top of your tank.

Mount these gauges on the flat end of a horizontal, cylindrical tank to monitor diesel fuel, fuel oil, or gasoline level.

Monitor hydraulic fluid or oil level in pressurized applications.

Monitor hydraulic fluid or oil level in gear boxes, crank cases, and other reservoirs.

The nylon body and window make these indicators shatter resistant.

Mount these indicators from the inside of your tank through unthreaded holes.

Shut-off valves stop flow so you can clean and replace gauge glass without removing these indicators from your equipment.

Detect sludge in your container; an alarm sounds when the indicator comes into contact with sludge.

Use this gauge glass with heavy duty level indicators.

Monitor liquid level in applications that have vibration, high pressures, and high temperatures. These indicators are also known as armored level gauges.

Measure liquid level with sound waves—these transmitters don’t come into contact with the liquid so you don't have to worry about fluid compatibility or contamination.

These sights have a glass window.

Continuously monitor oil quality through the clear plastic reservoir, and use the attached drain valve to remove water accumulation.

Easily view liquid movement and level changes from a distance—these sights have an indicator ball inside the glass window.

With a thick glass window fused to a metal body, these sights resist cracking at high pressures.

Mount these sights from the inside of your tank and secure with a lock nut.

Add a window to your high-vacuum system. With a pane of borosilicate glass sealed inside a high-vacuum CF flange, these sights bolt onto vacuum chambers, tee fittings, and manifolds.

Monitor food, brewery, chemical, pharmaceutical, and biotech processing lines with these sights that attach to quick-clamp fittings for fast installation and easy removal for cleaning.
