Define gas flowrates in the field or in the laboratory
New Star Environmental
The Definer 220 flowmeter (photo) allows users to verify gas flowrates in the laboratory or in the field, to an accuracy of±1% of reading, including temperature and pressure compensation. Unlike thermal mass flowmeters, the Definer 220’s positive-displacement technology provides immediate indication of actual volumetric gas flowrate, accurately and independently of the gas type, says the company. Integrated temperature and pressure sensors in the flow stream allow users to automatically standardize volumetric flow readings to standard conditions.— New Star Environmental, Roswell, Ga.
