Sponsler EFR Precision Turbine Flowmeter: the Best Flowmeter for Test Stand Applications employs a unique axially mounted rotor in the flow stream to measure flow volume with high accuracy and repeatability. An integral transducer outputs an AC signal that is used to generate rate of flow and totalization in a choice of meter-mounted or remote-mounted electronic devices. With the Sponsler EFR Series design, requirements for downstream thrust bearings are eliminated because the rotor does not rest against any surface when operating in its linear range. Therefore, the Sponsler EFR Precision Turbine Flowmeter represents, typically, only 1 psid at nominal flow. Resulting flows can be measured at accuracy of up to .15% with .02% repeatability within linear measurement ranges. For thirty years, Sponsler, Inc. has gained a reputation as a manufacturer of quality precision flow products engineered, manufactured, and tested to withstand the most severe operating problems related to viscosity, extreme temperatures, and corrosive or hazardous materials.

The new Sponsler IT400 Rate Indicator and Totalizer includes features such as battery power, linearization, temperature compensation, magnetically activated backlighting, and a dual segment low-battery warning. The Sponsler IT400 Rate Indicator and Totalizer is even smart enough to alert you of maintenance needs, notify you when the range of rate is over/under limit indications, and, if activated, inhibit totalization during alarms. The Sponsler EFR Series Precision Turbine Flowmeter with the IT 400 Rate Indicator and Totalizer are designed to give years of low-maintenance service while setting new testing industry standards for the high accuracy and reliability expected of Sponsler products.
