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 gear boxes, crank cases, and other reservoirs.

Mount these indicators on the outside of tanks in food, pharmaceutical, and other sanitary environments to monitor their liquid levels.

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

These indicators mount from the outside of your tank.

The nylon body and window make these indicators shatter resistant.

Replace existing gauge glass or combine with valves and guard rods to build your own level indicator.

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

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

Also known as level loggers, level sensors, and pressure transducers, these transmitters sit at the bottom of your tank in applications that make traditional mounting difficult.

The window and body are made from a single piece of plastic, making these sights more shatter resistant than sights with 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.

Often used in kilns and other heating equipment, these sights have a quartz window that can withstand temperatures up to 1600° F. They're also known as peep sights.

Weld these sights to single-wall tanks.

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

Fasten the extended flange to tank walls.
