Gas Turbine Meters

Gas Turbine Meters

Cox Precision Gas Flow Meters are designed for precise and repeatable flow measurement of all compressible fluids, with the added benefit of minimal pressure loss. To accommodate the requirements of most gaseous flow applications, Cox Precision Gas Meters come in a variety of sizes, end fittings and options. The gas models feature three basic rotor designs to compensate for low, medium and high density gases.


  • Meets application requirements for temperature and electronic outputs
  • Ceramic bearings provide near-perfect roundness, superb Rockwell hardness and for the elimination of adhesive wear. High performance ceramic bearings are versatile and can be used for water, cryogenics and hydrocarbon fluids
  • Rotor blade angle is matched the density of the gas to optimize the flow range
  • Calibrations performed in a NVLAP* accredited primary standards laboratory with audited uncertainty disclosure

*Note: NVLAP accreditation applies only to the Badger Meter Flow Dynamics calibration Lab, located in Racine, WI (Lab Code 200668-0) ​


  • Comprehensive pickoff selection
  • High-performance ceramic ball bearings
  • Three rotor designs
  • NVLAP* (Lab Code 200668-0) accredited facility with NIST traceable standards

Cox Flow Straighteners

Cox Flow Straighteners More Info Less Info

Cox Flow Straighteners are recommended for use with turbine flow meters to prevent false readings resulting from fluid swirl. Installed upstream and downstream of a turbine meter, they are designed to reduce liquid rotation by means of a six-vane swirl eliminator and a straight runs of tubing. (The swirl eliminator is not used on sizes below 1/2")

Cox Signal Conditioning Amplifiers

Cox Signal Conditioning Amplifiers More Info Less Info

Cox signal conditioning amplifiers (SCAs) accept low level pickoff signals and produce a stable, amplified pulse output. These SCAs are designed for magnetic or radio frequency (RF) pickoffs and are provided in multiple product configurations:

  • MS plug-in connector
  • Standalone wire terminal puck
  • Wire terminal puck in explosion-proof housing and pickoff
  • Wire terminal puck in NEMA 4 rated box

Digital-to-Analog Converter

Digital-to-Analog Converter More Info Less Info

Cox Digital-to-Analog Converters accept frequency inputs from turbine flow meters and produces an analog signal output. These converters are designed for magnetic or radio frequency (RF) pickoffs in two different product configurations. Converters are offered as either pucks only with wiring terminals, or in a "Y-3" explosion proof enclosure with magnetic or radio frequency pickoffs.

Non-interacting ZERO and SPAN adjustments make it easy to calibrate to any measurement range. All inputs and outputs are fully protected against reverse polarity or shorts to the power supply or ground
