Gas flow sensor: Tough exterior solves rough stack gas measurements

05/17/2007


Measuring stack gas flows with fly ash, dust, and grit can be hard on instrumentation, but it is often required for EPA compliance. A new multi-point mass flowmeter from Fluid Components International (FCI) uses a chromium-carbide coating on exposed surfaces to protect it from dirty, hot, and abrasive particulates. A single unit can have up to 16 measuring points on a variable length probe to create an accurate flow average given the complicated distribution profiles often present in gas ducts larger than 24 in.


The MT91 mass flowmeter is reportedly designed specifically for CEMS (continuous emission monitoring system) pollution control applications. The thermal mass flow sensor technology has no moving parts and can operate in temperatures up to 850 °F (455 °C). The unit will find a welcome home in the oil/gas, chemical, electric utility, cement, primary metals, and other heavy manufacturing industries.

The transmitter uses a microprocessor-driven design for signal processing and data collection. A menu-driven interface with LCD and keypad supports configuration and user-defined programming. The electronics package can be separated from the actual sensor up to 1000 ft using a cable. RS-232C and HART communication ports offer connectivity to controllers or other field devices.
