Compact Flow Sights with Indicator for Water and Oil
For visual confirmation of flow from a distance, these sights have a ball indicator that moves when flow is present. They have a low-profile body for installation in pipelines with limited clearance. Backlight the back window to increase the visibility of dark liquids.
Sights with a 303 stainless steel body are more corrosion resistant than sights with a brass or zinc-plated steel body.
