Fluid Components has released a video for engineers with difficult flowmeter applications that offers a tour of the company’s flow calibration lab and provides an overview of the calibration process.

The video explains the importance of flowmeter calibration with actual gases to achieve superior accuracy rather than using inferred air equivalency methods.

The Fluid Components laboratory features more than 18 National Institute of Standards (NIST) traceable precision flow stands.

All laboratory equipment is also ISO 9001:2000 and AS9000 compliant and also meets MIL-STD-45662A and ANSI/NCSL-Z-540 requirements.

Testing flow meters at Fluid Components flow calibration laboratory ensures they meet published and custom-designed instrument specifications, which is fundamental to performance at high levels of accuracy and repeatability.

The laboratory provides gas flow calibration capabilities ranging as low as 0.001scfm (0.00017ncmh) to ranges that exceed 5,000scfm (8,500ncmh) and higher for line sizes in excess of 10in (250mm).

Flow calibrations for applications with temperature ranges from -73C to +538C and pressure ranges from 0-1,000psig are commonly performed for many fluid services.

The company’s compressed-air test is designed for high-pressure and high-flow-rate air applications reaching up to 1,000sfps (300mps).

This enables Fluid Components’ flow technicians to calibrate meters at exact pressures/flow rates without needing to rely on extrapolations, resulting in improved performance.

The laboratory also features a liquid fuel flow stand developed primarily for Fluid Components’ aerospace division to calibrate meters in liquid hydrocarbons, jet fuel and water/ethylene glycol blends.

The stand uses two, NIST-traceable Coriolis flowmeters for high accuracy and can calibrate in virtually any mixed liquid composition.

Fluid Components said its customers can experience the benefits of guaranteed higher accuracy when their meters are calibrated with their actual fluids.
