Inline gas flow measurement for flue gases and process air

Accurate inline flow measurement

Essential for emissions calculations and process control.

Gas velocity in ducts can be measured using different measurement principles, depending on the application. DURAG differential pressure flow meters are designed for gas velocity measurement in dry gas applications. These robust in situ instruments are suitable for high process temperatures, elevated pressures, and ducts with small diameters.

DURAG ultrasonic flow meters determine gas velocity using ultrasonic signals transmitted and received between two identical sensors. This non-contact measurement principle provides reliable, continuous flow measurement in dust-laden environments, wet or dry gas applications, and even aggressive gas compositions.

Do you need to monitor additional process parameters? DURAG dust emission and ambient dust monitoring systems integrate seamlessly with these flow measurement solutions and are ideally suited for Continuous Emissions Monitoring Systems (CEMS).
