The FTM94 / FTM95 are industrial-grade thermal-mass flow transmitters / air-velocity sensors designed to measure air (or gas) flow velocity and volume in ducts, pipelines, or ventilation systems. Using a hot-wire (or hot-film) thermal sensing principle, they provide accurate, real-time flow (velocity & volume) and temperature data, even in demanding environments. The devices feature robust housings, analog or digital output options, and are suitable for tough industrial conditions.
Monitoring air or gas flow velocity and volume in ducts, vents, and pipelines
HVAC ventilation control and HVAC system balancing
Industrial airflow measurement in plants, factories, or process-air ducts
Clean-room airflow monitoring, air-handling units, and exhaust/intake systems
Compressed air usage measurement, exhaust gas monitoring, and process-air monitoring
