FLW-100 Ultrasonic Gas Flow Meter

The FLW-100 Ultrasonic flowmeter is designed based on the principle of the time difference of flight of ultrasonic waves. There is a pair of ultrasonic transducers installed inside the pipeline, facing each other and forming a certain angle with the direction of the flue emission flow. Under the influence of the flue emission flow, the flight time of the ultrasonic wave traveling downstream is shortened, while the flight time of the ultrasonic wave traveling upstream is extended. The higher the flue emission flow velocity, the bigger the difference in flight time.

Through measuring the flight time difference of the ultrasonic waves, the flue emission flow velocity can be calculated. This velocity is the average velocity along the path of the ultrasonic wave. Combined with the cross-sectional area of the pipeline at the measuring point, the instantaneous flow velocity can be calculated.

Real-time measurement of temperature, pressure, velocity, and flow rate of flue gas in environments with large diameter, low velocity, high dust content, high temperature, and high humidity. eg. coal chemistry, petrochemical, steel plant, metallurgy, cement plant, waste incineration.
