Precision Turbine Flowmeters - Liquid

COX has remained the flow meter of preference world wide for over 50 years, providing dependable data over wide flow ranges.  Calibration labs agree, that COX is one of the most linear and repeatable flowmeters on the market.  Being specified in numerous government and aerospace applications, is a tribute to the endurance and performance of COX turbine flowmeters.  With design characteristics, such as, helical rotors, an extended leading flow straightener and a press fit rear support, result in reliable and repeatable flow measurements.  These strengths are complemented by the signal conditioning and flow computers offered by Cox Instruments. AN Series Flow Meter

COX turbine flowmeters are found in numerous applications, such as, test and measurement labs, test stands, government applications, aircraft test cells, automotive testing or wherever precision flow measurements are paramount to success. 

COX offers custom calibrations in all types of fluids, including, universal viscosity curves to cover a wide operating temperature range.  Our calibrations are performed in Flow Dynamics' NVLAP facility, ensuring the optimum in calibration accuracy and repeatability.  

COX flowmeters offer:

  • Wide linear ranges, and when coupled with a flow computer, will measure accurately over the entire extended repeatable range.
  • Calibrations in various fluids and viscosity blends.
  • Universal Viscosity Curves for extended temperature environments.
  • Non-corrosive stainless steel wetted parts.
  • Various end fittings – AN, NPT, Flanges - including specials to meet your piping requirements.
  • Manifold systems, for extend flow range coverage.
  • A complete line of ancillary electronic signal conditioners and flow computers.
