Monitor hydraulic fluid or oil level in pressurized applications, such as hydraulic systems where overflow is a concern.

Made with clear, shatter-resistant plastic, these indicators don't require a shield to protect them like other oil-level indicators, so you can check your hydraulic fluid or oil level from any angle.

Check the level of liquids containing chemicals such as alcohol-based solvents, boric acid, and sodium bicarbonate.

Check both the temperature and the hydraulic fluid or oil level in a pressurized system.

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

Avoid overfilling—these indicators pop up when your tank is almost full.

These sights have a glass window.

View tank contents from multiple angles through the plastic domed window.

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

Press these sights into a hole in your tank wall; no additional mounting nuts are needed. They mount from the outside.

Check the contents of your tank from multiple angles with the domed window. To mount these sights, fasten their extend flange to tank walls.

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.

With a stainless steel float and float rod, these gauges resist corroding from chemicals.

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

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

Use these transmitters to measure the levels of corrosive, dirty, or sticky liquids without coming into contact with them.

FM and C-FM approved, these transmitters safely measure liquid levels where explosive gas or dust may be present. Set them at the bottom of your tank in applications that make traditional mounting difficult.
