Flow Sights & Indicators

Flow Sights & Indicators

Verify that liquid is flowing through a system with these flow sights. They provide a window into a closed tank or system so you can monitor the clarity and condition of the liquid inside it as well as the liquid level and mount inline with pipes for easy integration into your system. Sights have few moving parts and require little maintenance, but must be checked for scratches or damage regularly, as a scratch in the lens can result in a significant pressure rating reduction.

Visible Rotor

Estimate the flow rate of liquids through your system or confirm that liquid is flowing by watching the rotor in these flow sights turn. They have a removable clear lens for easy cleaning and maintenance.

Industrial Grade

These heavy-duty sights have windows made of tempered borosilicate glass for exceptional strength and high-temperature resistance. Commonly used in petrochemical, pharmaceutical, and other industrial applications, the windows are also gasketed to help prevent leaks or pressure loss.

Install these flow sights on gearboxes or pumps to get a clear view of the clarity and condition of the lubricant flowing through them. They have a baffle that helps regulate flow in turbulent conditions, and the lenses can be quickly removed for cleaning when out in the field.
