EC80 Flow Processor
Brand: Cox Instruments
The Cox EC80 Flow Processor is a programmable electronic processor, providing total compensation to enhance flow meter accuracy, while extending the linear flow range.
Packaging is provided for remote, direct or embedded mounting to support most installation or application requirements. The compact design includes both single and dual frequency inputs from 4 or 10 ohms pickups, as well an RTD input and an additional Analog input for other temperature inputs.
The EC80 processor tracks all variables to compensate for viscous and inertial effects, using proven Strouhal-Roshko algorithms. Enhanced DSP technology allows for exceptional signal characterization using a 32-bit floating point processor at 150 MHz, capable of producing a 100 microsecond speed of response.
Features- Rotor blade pulse averaging
- Strouhal-Roshko computation, using 16-bit resolution
- Dual outputs provide both frequency and Analog signals
- Recallable and stored calibration data
- Internal amplifier and signal conditioners
- Assignable outputs
