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.

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.

The nylon body and window make these indicators shatter resistant.

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.

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

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

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