Sights for Quick-Clamp Sanitary Tube Fittings

Sight Shown Assembled With
Gasket, Quick-Clamp Fitting, And
Tube Fitting (All Sold Separately)

Glass Window with 2205 Stainless Steel Ring

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. All have a one-piece design, so there are no crevices where bacteria can grow. A quick-clamp fitting, gasket, and tube fitting are required (sold separately).

For superior strength and reliability, choose 2205 stainless steel sights. All have a glass window that’s melted around a high-strength ring, so they won’t shatter, leak, or lose their shape under high pressure, heat, chemicals, or impact. They withstand harsh cleaners and sanitizers for clean-in-place (CIP) and steam-in-place (SIP) applications. USP Class VI and TUV Rheinland Certified, these sights meet safety standards in the U.S. and Europe. They also meet DIN standards for glass materials used in sights, ASTM standards for materials used in boilers and pressure vessels, and ASME BPE design standards for bioprocessing equipment that ensure purity and safety.

Level Indicators with Shut-Off Valve

316 Stainless Steel With Ball-Valve-Style Drain

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

316 stainless steel indicators are more corrosion resistant than brass indicators.

Indicators with automatic shut-off will temporarily close if the gauge glass breaks. The valves must be closed manually for permanent shut-off.

Heavy-Duty Level Indicators

Indicator with Reflex Glass

Shut-Off Valve

Reflex Glass

Gasket

Monitor liquid level in applications that have vibration, high pressures, and high temperatures. These indicators have steel chambers, glass windows, and seals made of fiber and SBR rubber to resist corrosion and withstand higher temperatures than other level indicators. Use them with a wide variety of liquids, such as petroleum, chemicals, and natural gas. All meet ASME BPVC.VIII.1 safety standards for pressure vessels, so they’re approved for use in low-pressure water and steam applications too. Their gauge is made of reflex glass, which shows the level of liquid behind the glass, but not the liquid’s color or any particulates in it. Also known as armored level gauges.

Add shut-off valves to stop flow with the turn of a wheel. They help you access indicators in order to clean or replace the glass or the entire indicator. These valves also stop flow automatically if the indicator glass breaks, preventing the loss of fluid. However, for permanent shut-off you must close them manually. Put one valve on top of your indicator and one on the bottom for a 90° connection between the indicator and your tank. To connect the female threads on your indicator to the female gauge threads on the shut-off valve, use a male pipe nipple (not included).

Chemical-Resistant Vertical-Mount Liquid-Level Gauges for Tanks

With a stainless steel float and float rod, these gauges resist corroding from chemicals. Their indicator moves up as your tank fills. Check the indicator against the graduation marks to see how full your tank is and if you need to fill or drain it. Plastic protects the indicator's movement, saving you from inaccurate readings.

Alarms can be set to flash and sound at levels critical to your system.

Remote-reading displays let you check readings from up to 100 ft. away. They have an alarm that sounds when the level is too high or too low.
