Power Generation Applications

Differential Pressure technology is commonly used to measure fluid velocity due to their well-defined relationship. The square root of the differential pressure is proportional to the velocity of the fluid. In ducted systems the total pressure consists of the velocity pressure and static pressure. By measuring the total and static pressures in a duct, the velocity pressure can be obtained by subtracting static pressure from total pressure. This is achieved in practice by directly measuring the differential pressure between the two. Airflow measurement over a large velocity range requires an extensive selection of DP transducers with multiple upper range limits (URLs) to fit the required application – from ultra-low range like 0.05” w.c. URL transducer and higher. Air monitor offers this ultra-low range DP sensing capability coupled with the Auto-zero function to provide a highly accurate DP measurement with long term calibration stability starting for 0.05” w.c. URL transmitters.
