JEF-500 Series Turbine Folwmeter

Short Description:

JEF-500 Series Turbine Flowmeters are available in a broad range of standard and special materials. The wide range of construction options allows for the selection of the optimum combination of useful range, corrosion resistance, and operating life for a particular application. A low mass rotor design allows for a rapid dynamic response which permits the turbine flowmeter to be used in pulsating flow applications.

Product Description

The deflector cones eliminate downstream thrust on the rotor and allow for hydrodynamic positioning of the rotor between deflector cones. The hydrodynamic positioning of the low mass rotor provides wider rangeability and longer bearing life than that of conventional turbine flowmeters. Integral flow straightening tubes minimize the effects of upstream flow turbulence. The housing is made of non-magnetic materials. The rotor is made of magnetic or magnetized material. Bearings are chosen based on service fluid, cost, and accuracy considerations
