Precision Meters Turbine Flow Meters DESCRIPTION Cox Precision Turbine Flow Meters have unprecedented mechanical linearity, resulting in minimizing, or negating, temperature induced viscosity influence. Cox Precision Turbine Meters come with a variety of process fittings, sizes and options to accommodate the requirements of most applications while offering wide flow ranges. Features Benefits Expanded Increased usable flow range with less mechanical linearity sensitivity to fluid temperature/viscosity effect on the output. APPLICATIONS Helical rotor design Exceptional speed-of-response, with reduced pressure drop. Cox Precision Flow Meters are the ideal solutions for standard and high pressure liquid flow applications in test and measurement and precision industrial processes, found in the automotive, aerospace and general industries. Comprehensive pickoff selection Meets application requirements for temperature and electronic outputs. High-Performance Ceramic bearings provide near-perfect ceramic ball bearings roundness, higher Rockwell hardness and are lighter and more tolerant to temperature than 440C stainless steel bearings. They eliminate adhesive wear and perform well in non-lubricating liquids found in cryogenic fluids and water. OPERATION AND PERFORMANCE As a fluid passes through the meter, the velocity of the fluid provides rotational energy on the rotor. The rotor blades, passing through a magnetic or radio frequency field, generate pulses proportional to flow. Each pulse is transmitted to the meter electronics, where it amplifies the pulse output. 6-bladed rotor supports NVLAP accredited facility with NIST traceable standards verify that all calibrators produce the same result. A variety of end fittings Improved flow conditioning. Outstanding mechanical linearity, up to 100:1, is achievable, depending on meter size. Paired with a flow processor, meter linearity 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 compensated for by using thermal expansion coefficients, with Strouhal-Roshko equations, to provide a very accurate and repeatable volumetric flow rate. Third party audits to ensure calibration uncertainty. Laboratory correlation to AN, NPT, hose barb, flange, high pressure, tri-clamp and special fittings to meet specific installation configurations. Performance Speci?cations CALIBRATIONS Calibrations are accomplished by using various blends of solvent and oil to simulate actual fluid conditions. For varying process temperature conditions, multiple viscosity calibrations are used to develop a universal viscosity curve. UVC calibrations enable a flow computer to track temperature and compensate for fluid viscosity. Flow Dynamics tailors calibrations to replicate process conditions so the meter is characterized to provide the best attainable accuracy. • • • • • • Repeatability: ± 0.02% of reading Linearity: ± 0.5 0% (± 0.1% with flow processor) Calibrator Uncertainty: ± 0.05 % of reading Frequency Output: 1200…15 00 Hz Response Time: 2…3 ms (at 1.2 cSt) Pressure Ratings: See “Pressure Speci?cations” on page 5 Calibrations are performed by our Flow Dynamics NVLAP (Lab Code 200668) accredited calibration facility, which uses primary standard calibrators, offering uncertainties of ± 0.05 percent of reading with ± 0.02 percent repeatability. Users can be assured that Cox Precision Meters come with a best-in-class calibration, traceable to NIST standards.  Product Data Sheet TUR-DS-00169-EN-02 (September 2013) Precision Turbine Flow Meters CONSTRUCTION METER INSTALLATION Cox Precision Meters feature 316 stainless steel housings. Wetted materials include axial helical rotors, made of 17-4 stainless steel, that rotate on robust ceramic ball bearings. The supports and all other materials are made from 300 series stainless steel. High pressure meters come standard with AS33514 fittings. End Fittings are fully compliant with AS33514 and AS4375. For pressure ratings, see “Pressure Speci?cations” on page 5. Cox Turbine Flow Meters mount directly in the piping and can be installed in any position without affecting performance. For optimal performance, recalibrate the meter if the mounting orientation is changed from the original horizontal calibration. To reduce flow turbulence, a straightener section of tube, at a minimum of 10 diameters in length upstream and a similar section at a minimum of five diameters downstream, is recommended. If this recommendation is impractical, due to space limitations, pay careful attention to the location of valves and bends. To compensate for piping bends, meters can be calibrated in the same piping configuration. Flow straightener sections are available from Cox Flow Measurement. For best performance and longevity, upstream filtration (10...75 micron, depending on meter size) is helpful, to prevent bearing contamination and to avoid rotor blade damage.

Radio frequency (RF) pickoffs extend the measurable linear flow range by eliminating magnetic induced drag. RF pickoffs require a power input, whereas magnetic pickoffs generate their own power to produce an output signal and typically, have greater tolerance to higher process temperatures.

Chart is displaying safe working pressure, in accordance with power piping code ASME B31.1. NOTE It is recommended that the flow meter have “AN”end fittings and that the “NPT”transition be done on the far ends of the flow straighteners. This avoids a step in the flow stream next to the flow meter and produces an improved flow profile. If the NPT end fittings were selected for their high pressure rating, then the step is unavoidable and the calibration will account for the distorted profile.

XXX Calibration Service Number Definition Fluid Viscosity represents the fluid viscosity desired. Flow Rate COX精密涡轮流量计represents process flow rate in gallons per minute. Data Points represents the resolution of the calibration. The more data points that are used, the more accurate the data curve plot. Number of Viscosity Calibrations indicates how many different fluid viscosities are required. Calibration Type • • • “S”represents a calibration that uses only one fluid viscosity. “M”represents a calibration that uses multiple fluid viscosities. “U”represents a calibration that places multiple fluid viscosities in a universal viscosity curve. Data Point Spacing indicates how data points are graphed. Special identifies a design or configuration change that is unique to the calibration.COX精密涡轮流量计
