Fluid Components Intl. Multipoint thermal mass flowmeters
MT100 and ST102A multipoint thermal mass flowmeters measure recycled hot air from stack gases to reduce fuel consumption. The MT100 flowmeters are available with two to eight airflow rate sensing points to ensure compatibility with large-diameter piping and large ducts. The sensors are inserted at various depths within the duct or pipe, and their outputs are multiplexed and averaged to measure the flow rate. They can be installed across a mast or as discrete, single sensors inserted at multiple points around a large duct or round pipe in a single plane. The ST102A flowmeter is available with two multiplexed thermal sensors. It features adaptive-sensor technology (AST) thermal mass flow sensor drive technology.
