MT100 Series – Air and Gas Flow Meter Solutions Designed for Large Pipe and Duct Applications Large diameter pipes and ducts present unique challenges to achieve successful flow meter installation and performance. Lack of straight-run, distorted flow profiles, low flow rates and wide turndowns rates are common performance challenges for many flow metering technologies. Installations can be complicated by difficult access points, single plane platforms, long cable runs, extra mechanical support and exposure to weather extremes. Further, in many applications, the gas being measured can be dirty and/or at high temperatures which can result in measurement degradation, clogging and fouling leading to excessive maintenance procedures or premature failures of many flow meter technologies. FCI has been providing application optimized, low maintenance and cost effective air/gas flow meter solutions for large pipe and ducts for more than three decades.

FCI’s MT100 Series combines state-of-the-art, precision electronic technology with application proven flow sensors and plant ruggedized packaging to provide you with a highly accurate, reliable and low maintenance flow meter solution for large diameter pipes, stacks and rectangular duct installations. The MT100 Series is a multipoint, direct mass flow meter for air and gases, using thermal dispersion mass flow technology. Depending on installation conditions and line size, FCI application engineers will recommend from two (2) to eight (8) flow rate sense points. The sensors are inserted into pipe/duct and multiplexed to produce an averaged output of flow rate within the process line. To best optimize the installation, the sensors may be installed across a mast* (or bar) or may be single-point sensors* inserted at multiple points around the process line. Further, because sensors are installed in a single plane, installations in large stacks can be accomplished from a single platform. This achieves significant savings in installation costs and complexity over flow meter technologies such as ultrasonics which require transducers to be installed at a precise offset angle. The MT100 sensors excel in the application because there are no moving parts or orifices to foul or clog and it can be applied in process temperatures up to 850 °F [454 °C]. The MT100 transmitter provides an extensive choice of output options for interface with virtually any DCS, PLC, SCADA, recorder or control system. Its large color LCD touch-screen has digital displays, bar graph, trend graph, diagnostic and more, to provide you best-in-class process information. For CEMS applications, MT100 has optional features and functions to meet EPA requirements.

Your investment in an MT100 Series flow meter is completed with FCI’s precision calibration. Calibration is performed in FCI’s world-class flow calibration laboratory using equipment traceable to NIST (US National Institute of Standards and Technology) and ISO/IEC 17025 international standards for test lab quality systems. Calibrations are matched to your gas and process conditions resulting in best possible installation accuracy and repeatability for your installation.
