FDM06S Differential Pressure Type Air Flow Transmitter

● Adopting the differential pressure principle for air flow measurement
● Enable bi-direction air flow measurement
● Measures differential pressure, pressure, and temperature simultaneously
● Special diversion design reduces the impact of air flow turbulence
● Calculate medium density and mass flow rate
● Rugged and durable design for high temperature and high-pressure environment
