Cox Precision Turbine Meters come with avariety of process fittings, sizes and options to accommodate therequirements of most applications while offering wide flow ranges.FeaturesBenefitsExpandedIncreased usable flow range with lessmechanical linearity sensitivity to fluid temperature/viscosityeffect on the output.APPLICATIONSHelical rotor design Exceptional speed-of-response, withreduced pressure drop.Cox Precision Flow Meters are the ideal solutions for standard andhigh pressure liquid flow applications in test and measurement andprecision industrial processes, found in the automotive, aerospaceand general industries.Comprehensivepickoff selectionMeets application requirements fortemperature and electronic outputs.High-PerformanceCeramic bearings provide near-perfectceramic ball bearings roundness, higher Rockwell hardnessand are lighter and more tolerant totemperature than 440C stainless steelbearings. They eliminate adhesive wearand perform well in non-lubricatingliquids found in cryogenic fluids andwater.OPERATION AND PERFORMANCEAs a fluid passes through the meter, the velocity of the fluidprovides rotational energy on the rotor. The rotor blades, passingthrough a magnetic or radio frequency field, generate pulsesproportional to flow. Each pulse is transmitted to the meterelectronics, where it amplifies the pulse output.6-bladed rotorsupportsNVLAP accreditedfacility with NISTtraceable standards verify that all calibrators produce the sameresult.A variety of endfittingsImproved flow conditioning.Outstanding mechanical linearity, up to 100:1, is achievable,depending on meter size. Paired with a flow processor, meterlinearity improves from the standard ± 0.5 0 percent to within± 0.1 percent of reading over the entire repeatable flow range,while providing fluid temperature viscosity compensation.Temperature effects on the meter bore diameter are compensatedfor by using thermal expansion coefficients, with Strouhal-Roshkoequations, to provide a very accurate and repeatable volumetricflow rate.Third party audits to ensure calibrationuncertainty. Laboratory correlation toAN, NPT, hose barb, flange, high pressure,tri-clamp and special fittings to meetspecific installation configurations.Performance Speci?cationsCALIBRATIONSCalibrations are accomplished by using various blends of solventand oil to simulate actual fluid conditions. For varying processtemperature conditions, multiple viscosity calibrations are usedto develop a universal viscosity curve. UVC calibrations enablea flow computer to track temperature and compensate for fluidviscosity. Flow Dynamics tailors calibrations to replicate processconditions so the meter is characterized to provide the bestattainable accuracy.??????Repeatability: ± 0.02% of readingLinearity: ± 0.5 0% (± 0.1% with flow processor)Calibrator Uncertainty: ± 0.05 % of readingFrequency Output: 1200…15 00 HzResponse Time: 2…3 ms (at 1.2 cSt)Pressure Ratings: See “Pressure Speci?cations" on page 5Calibrations are performed by our Flow Dynamics NVLAP (Lab Code200668) accredited calibration facility, which uses primary standardcalibrators, offering uncertainties of ± 0.05 percent of readingwith ± 0.02 percent repeatability. Users can be assured that CoxPrecision Meters come with a best-in-class calibration, traceable toNIST standards.
