Hoffer 3A Sanitary Turbine Flowmeters for Liquid Applications
The Hoffer 3A sanitary turbine flowmeter is designed measuring process liquids in clean applications. For optimum performance, this flowmeter requires a minimum of 10 pipe diameters upstream and 5 pipe diameters downstream. This turbine flowmeter must be installed with the pickup coil pointing downward to ensure proper cleanability per the 3A sanitary standard.
Key Specifications
- Meets 3A Sanitary Standard 28-03 for measuring process liquids
- Available in sizes from 1/4" to 3" with Tri-Clamp™ fittings
