Flow Sights with Indicator for Water and Oil


Ball Indicator	Rotor Indicator Front Window

Rotor Indicator Front and Back Window

The indicator moves when flow is present, so it’s easy to visually confirm flow from a distance.

Ball Indicator—Ball indicator shows flow more prominently for easier viewing at a distance.

Rotor Indicator—Rotor indicator is the most obvious indicator of flow for maximum visibility.

Polypropylene Body—Sights with a polypropylene body are lighter than sights with a metal body.

Bronze Body—Sights with a bronze body are harder and more durable than sights with a brass body for a longer service life.

316 Stainless Steel Body—Sights with a 316 stainless steel body are more corrosion resistant than sights with a brass or bronze body.

Front and Back Window—Back window can be backlit to increase the visibility of dark liquids.

Compact Flow Sights for Water and Oil

The low-profile body fits in areas with limited clearance. These sights let you visually confirm flow and inspect liquid color and clarity. The back window can be backlit to increase the visibility of dark liquids.

303 Stainless Steel Body—Sights with a 303 stainless steel body are more corrosion resistant than sights with a brass or zinc-plated steel body.

High-Temperature Flow Sights for Water and Oil

Flapper Indicator

Withstand twice the temperature of standard flow sights for applications with temperatures up to 400° F. These sights let you visually confirm flow and inspect liquid color and clarity. The flapper indicator moves when flow is present, so it’s easy to confirm flow from a distance. Backlight the back window to increase the visibility of dark liquids. The brass body of these sights resists corrosion.

High-Pressure Flow Sights for Water and Oil

Rated for more than double the pressure of standard flow sights, these can withstand pressures up to 400 psi. They’re used to visually confirm flow and inspect the color and clarity of your process media. All have an indicator that moves when flow is present for checking flow from a distance. Backlight the back window to increase the visibility of dark liquids.

Flapper Indicator—Flapper indicator provides a subtle indication of flow.

Rotor Indicator—Rotor indicator provides a more obvious indication of flow than a flapper indicator for maximum visibility.

316 Stainless Steel Body—Sights with a 316 stainless steel body are more corrosion resistant than sights with a steel or bronze body.
