The MT100 Series is an insertion type, multipoint thermal flow meter specifically designed for large diameter pipes, such as stacks, industrial chimneys, and flues, and large rectangular ducts, such as air feed intakes and HVAC. These large pipe/duct applications are difficult for ordinary flow meters because of distorted flow profiles and lack of straight-run that can lead to inaccurate and non-repeatable flow measurement. FCI's MT100 places up to eight (8) flow sensing points in the flow stream and averages them which results in a highly accurate and repeatable flow rate measurement. The insertion design, in the same plane, makes them an easy and lower cost solution to install.
