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

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

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.

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

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

Bend these flexible indicators around the contours of your hydraulic fluid, oil, or water tank. Because their plastic resists shattering, they don’t need a protective shield like other liquid-level indicators, so you can check your tank’s level from any angle.

Combine a pair of valves with a gauge glass and four guard rods to build a complete level indicator.

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

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

Often used in cooling, lubrication, and process systems.

A ball indicator increases the visibility of flow for checking at a distance.

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