These flexible indicators bend to follow the contours of a tank.

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

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

Simultaneously monitor hydraulic fluid or oil level and temperature in gear boxes, crank cases, and other reservoirs.

To maintain a clear view of your process media without disrupting flow, twist the tubular window to clear debris and buildup with the internal wipers.

Barbed fittings slide into soft plastic and rubber tubing.

Built to withstand harsh chemicals.

Peer through the glass on these flow sights to see what’s happening in your high-vacuum line.
