How does a Hoffer flow meter work?

Flow meter Mounted within the body of a Hoffer liquid turbine flowmeter is a vaned rotor. The rotor is centered on a shaft and allowed to rotate by means of bearings. The shaft is supported in the housing by tube...

What is a turbine flowmeter?

Turbine flow meters Hoffer turbine flow meters measure the average velocity of a fluid flowing through the body of the meter. The average velocity multiplied by the cross-sectional flow area equals the volumetric flow rate. For over forty-five years Hoffer...

What makes Hoffer Flow meters different?

Turbine Flowmeters - Rotor Construction - Precision Machined • All Rotor assemblies are precision machined • Hoffer does not use cast rotors. • Cast rotors are “heavier” than rotors machined from solid bar stock. Heavier rotors translate to slower dynamic...

What is an inline Turbine Flowmeter?

What is an inline Turbine Flowmeter? Principle of operation of an inline turbine flowmeter: Hoffer inline turbine flowmeters are velocity measuring devices, which is to say they measure the average velocity of a fluid flowing through the body of the...
