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

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

Seal the glass on your level indicator.

The nylon body and window make these indicators shatter resistant.

Monitor hydraulic fluid or oil level in pressurized applications.

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

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

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

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

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

Machined from one piece of stain- and impact-resistant plastic.

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

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

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.

Weld these sights to single-wall tanks.

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

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.

For precise measurement of water, hydraulic fluid, or diesel fuel level, this gauge provides level readings down to 1/8".

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

The indicator moves when flow is present, so it’s easy to visually confirm flow from a distance.

For visual confirmation of flow from a distance, these sights have a ball indicator that moves when flow is present.

Withstand twice the temperature of standard sights. These are rated for temperatures up to 400° F.

Rated for more than double the pressure of standard flow sights, these can withstand pressures up to 400 psi.

A large tubular window provides an unobstructed view of liquid color, clarity, and movement from multiple angles.

Barbed fittings slide into soft plastic and rubber tubing.

Built to withstand harsh chemicals.

Reach deep into small holes and slots for precise depth measurements.
