Create gas mixtures with ease to calibrate flowmeters
Sierra
When changes in gas composition occur in the field, the accuracy of flowmeters can be adversely affected. The Quadra Therm 64oi/78oi (photo) allows field engineers to adjust the composition of calibration gas for thermal mass flowmeters in the field, to improve the operating reliability and safety of flares, vapor-recovery units and storage vessels. The device relies on the company’s proprietary gas-mixing software package. This software lets engineers and operators create, customize and upload an unlimited number of gases and gas mixtures, as needed, to compensate for gas compositional changes in the field, without any loss in flowmeter accuracy, says the company. — Sierra, Monterey, Calif.
