Cox Instruments, a supplier of precision flow-measurement instrumentation, has announced the opening of an Asia/Pacific primary-standard flowmeter calibration centre.

Operated under an agreement with NTK International, the NTK/Cox calibration facility is located at 417-1 Shimoongata, Hachioji-City, Tokyo, Japan.

The NTK-Cox calibration lab provides primary standard NIST-traceable liquid calibrations for all type of flow measurement devices, ranging from 0.01 to 300Gpm in fluids from 0.5 to 100cSt.

Common flowmeters calibrated at the centre include: Turbine, Positive Displacement, Venturi/Nozzle, Rotameter, Orifice Plate, Coriolis, Ultrasonic, V-Cone, Vortex and Variable Area Flowmeter (VAM).

The facility offers liquid flowmeter calibration services meeting both end user and OEM production requirements.

It verifies flowmeter accuracy by comparing the meter under test with a primary flow standard traceable to a recognised international standard, such as the US National Institute of Standards and Technology (NIST).

The centre’s Cox-trained calibration service team takes into account key factors affecting flowmeter performance, such as orientation of the meter, operating temperature and pressure, and the type of the flow medium and viscosity.

The NTK-Cox calibration service center uses advanced flow dynamics PDCL-10 and PDCL-300 primary-standard flow calibrators with an uncertainty of +/-0.05 per cent of reading.

The positive displacement calibrators precisely control the flow of liquid passing through the flowmeter under test, while monitoring fluid temperature.
