Precision Turbine Meters

Precision Turbine Meters

Cox Precision Turbine Flow Meters have unprecedented mechanical linearity, resulting in minimizing, or negating, temperature induced viscosity influence. With a variety of process fittings, sizes and options available, Cox meters are able to accommodate the requirements of most applications while offering wide flow ranges.


  • Increased linear flow range with less sensitivity to fluid temperature/viscosity effect on the output
  • Exceptional speed-of-response, with reduced pressure drop
  • Carrier frequency pickoffs eliminate rotor drag while magnetic pickoffs provide for high temperature and remote powerless installations
  • 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
  • 6 vane supports for improved flow conditioning
  • Calibrations performed in a NVLAP* accredited primary standards laboratory with audited uncertainty disclosure
  • AN, NPT, hose barb, flange, high pressure, tri-clamp and special fittings to accommodate specific installation configurations 

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


  • Expanded mechanical linearity
  • Helical rotor design
  • Comprehensive pickoff selection
  • High-performance ceramic ball bearings
  • 6-bladed rotor supports
  • A variety of end fittings
  • 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 Manifold System More Info Less Info

Cox turbine flow meter Manifold Systems are designed for applications where extremely wide rangeability, automatic operation, and high accuracy are required, such as in jet engine cells, fuel control stands and flow meter calibrating devices. With the Series 44 M, flow ranges of 100:1, 1000:1 or higher are available for high-pressure systems. The system consists of a stainless steel manifold with flow straightening sections, two or three turbine flow meters and one (or two in a three-element system) air-operated electrically controlled shutoff valve. Operation of the manifold system is automatic and fail-safe as normally open valves are used.

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
