Thermal mass flow meter

The MT91 Series Flow Meter from Fluid Components International (FCI) has a smart, self-checking digital flow transmitter and advanced thermal dispersion technology flow-sensing elements. It meets federal environmental requirements for CEMS per CFR Title 40, Part 75. The MT91 measures mass flow almost anywhere variable conditions and harsh environments limit single-point flow meter effectiveness. The MT91 Flow Meter features up to 16 averaging flow sensing points with no-moving parts operating over a wide temperature range up to 850°F [454°C]. 

 

The MT91 Flow Meter features a wide turndown range from 5:1 to 100:1 with a flow range from 0.25 SFPS to 150 SFPS (0,08 NMPS to 46 NMPS). Up to four meters can be installed to measure air/gas in the largest of stacks.   Measurement repeatability is ±0.5 percent of reading. 

 

The flow element incorporates two platinum resistance-temperature detectors (RTDs) for temperature and flow measurement.  All wetted surfaces are 316 stainless steel with nickel brazed joints per AMS 4777 (standard) or Hastelloy C-276 as an option.

 

The sensor assembly is available with flanged, threaded and retractable process connections.
