Product Details

Providing a quick and direct reading flow rate measurement of liquids in closed piping systems, this HEDLAND EZ-View® mechanical flowmeter is easy to mount in any position without costly flow straighteners or other special plumbing. The transparent body allows visual inspection of the fluid condition as well as viewing of the internal flow indicator relative to a calibrated flow scale. Model doesn’t need electrical connections and provides measurement by creating a predictable differential pressure across a sharp-edged orifice that is located in the piston assembly.
