The MT100 Series Multipoint Thermal Mass Flow Meters from Fluid Components International (FCI) aims to help accurately measure and control continuous or positive air flow. According to the company, continuous or positive air flow HVAC systems are installed to protect employees and operations from the potential harmful effects of toxic and combustible gases, such as leaking hydrogen sulfide (H2S), methane (CH4), and others. These specialized systems provide a continuous air flow pattern or passive barrier to separate staffed work areas or automated process areas (unstaffed) from hazardous areas where gas leaks can lead to accidents.
FCI’s MT100 Series Multipoint Air/Gas Flow Meters combine electronics technology with precision air flow sensors in an industrial package designed for demanding hazardous plant and building operating environments. The company claims the meters provide precision, temperature-compensated direct mass flow measurement of air for highly reliable, repeatable HVAC PID control with low maintenance requirements. All MT100 Series Flow Meters have been independently tested and verified to comply with IEC safety directives for EMC and LVD, and carry the CE marking. Optionally available for process installations with hazardous, potentially explosive gases and/or dust, MT100 meters can be ordered with FM/FMc, ATEX, or IECEx agency approvals for Division II/Zone 2.
FCI’s thermal mass MT100 Series Flow Meters are available with two to eight air flow rate sensing points to ensure compatibility with large diameter piping and large ducts. These multiple sensors are inserted at various depths within the duct or pipe and their outputs are multiplexed and averaged to accurately measure the flow rate. These multiple sensors can be installed either across a mast or as discrete, single sensors inserted at multiple points around a large duct or round pipe in a single plane.
The MT100 Flow Meters can measure flow rates over a wide range from 0.25 to 1000 SFPS (0,07 to 305 NMPS) with 100:1 turndown.. They are also dual-function to also provide air temperature measurement capability from -50°to 850°F (-45° to 454 °C).).
