Measure Dirty Gas Streams

The Multi-Trak Model 670S duct and stack mass flowmeter measures mass flow rates in very large ducts or stacks that have non-uniform velocity profiles, high turn-down requirements, dirty gas streams, wide temperature ranges and fast velocity and temperature changes.

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.
