Scottsdale, Ariz. — Flow Dynamics, Inc., a provider of primary standard, NIST-traceable calibrations for all types of flowmeters, has expanded its Scottsdale, Ariz., flow laboratory capability in order to provide calibrations for all COX Instruments turbine flow meters.
The Flow Dynamics lab recently added a new 300 GPM positive displacement primary standard calibrator (PDCL) that increased its calibration capacity throughput. The facility plans to install an additional PDCL calibrator later this year.
Flow Dynamics was the first independent flow calibration laboratory to receive prestigious National Voluntary Laboratory Accreditation Program (NVLAP) accreditation from the National Institute of Standards & Technology (NIST) in conformance with the standards of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).
Cox Instruments provides precision turbine flowmeters to customers with demanding liquid and gas flow metering requirements. Cox turbine meters provide a mechanical linearity from 15:1 on ½-in. meters and up to 100:1 on 2-in. meters, without the use of linearizing electronics. The precision line of flow meters achieves ±0.02% repeatability, with a combined accuracy of ±0.25% of reading. The helical rotor provides a fast response time of 2-3 milliseconds in MIL-C-7024C fluid.
All calibrations of Cox turbine flow meters, performed by Flow Dynamics’ NVLAP facility, are fully traceable to NIST guidelines and comply with ISO 17025, ISO 9002, ISO Guide 25, ANSI/NCSL Z-540 and MIL-STD-45662A.
