The ExactComp EC80 from Cox Flow Measurement, Scottsdale, AZ, works with the company's turbine flowmeter products to enhance the performance of frequency output flowmeters under varying fluid flow conditions. The device accepts 4- and 10-Ω pick-offs, includes dual-rotor frequency and RTD temperature sensor inputs for single or dual-rotor turbine flowmeters, and tracks all variables to compensate for viscosity and rotor blade variations by using selectable blade averaging coupled with a rolling average output. A 32-bit, floating point DSP operates at 150 MHz to provide process latency of 100 µs and outputs linearized data in engineering units.
