The flowmeters use up to four independent mass flow sensing points to
measure the instantaneous average gas mass flow velocity. The flow
meters provide an accuracy of +/-1% reading plus 0.5% of full scale,
one-second response to changes in flow rate, and patented Dry-Sense
Technology designed to eliminate sensor drift. The sensors are FM, CSA,
and ATEX certified for hazardous areas, and are CE approved.Sierra Instruments Inc.www.sierrainstruments.com800.866.0200
