Turbine flowmeter
The EFR series (enhanced floating rotor) is a precision turbine flowmeter (PTF) from Sponsler, Inc. It is designed to measure liquid and gas flows to custody-transfer standards, and is available in all industry-standard end-fittings. The axial design of the meter provides a rotor that is mounted on a shaft between flow cones at 90° to the flow. Requirements for downstream thrust bearings are eliminated because the rotor does not rest against any surface when operating in its linear range. Resulting flows can be measured at accuracy of up to 0.15% with 0.2% repeatability within linear measurement ranges.
