Precision Turbine Flowmeter from Cox Instruments
February 20, 2008
HP Series turbine flowmeters from Cox Instruments, Scottsdale, AZ, are available in ranges from 0.25–2.5 gpm to 25–250 gpm, depending on meter size. Available in a range of sizes, the flowmeters feature 0.25% of reading accuracy, 2–3 ms response time, MS33514 end-fittings, and the ability to withstand pressures up to 5000 psig (continuous), 7500 psig (proof), and 25,000+ psig (burst). Calibrations are NIST-traceable. With a standard K factor (10:1 flow ratio) calibration, frequency output is linear to within ±0.5% over the entire flow range for liquids with viscosities up to 1.26 centistokes. Meters provide a linear extended range from 15:1 on small meters, ranging up to 100:1 on 2 in. meters, without using linearizing electronics.
