Conforming to the temperature compensation calculations of SAE ARP 4990, the COX Flow Measurement ExactComp EC80 flow computer accepts 4- and 10-ohm pick-offs, and includes dual-rotor frequency and RTD temperature sensor inputs for either single- or dual-rotor turbine flow meters. It tracks all variables to compensate for viscosity and rotor blade variations by using selectable blade averaging coupled with a rolling average output. Enhanced Digital Signal Processing technology enables signal characterization using a 32-bit floating point processor at 150 MHz having a process latency of 100 µS, while outputting linearized data in engineering units. The computer is available with packaging for remote, direct or embedded mounting.
