چکیده

The experimental apparatus was composed of a water circulation system, an air supply system, a test section and a measurement system~ Air and water were used as working fluids. . The test section was a vertical rectangular channel of 10mmxlOOmmx700mm made of Plexiglas as shown in Fig.l. The measuremen.t system consisted of the UVP and a personal computer to record and treat data. Water was fed into the upper tank and flowed downward in· the test section. Micro particles of nylon powder were suspended in water to reflect ultrasonic pulses. The air supply system consisted of a compressor and a pressure regulation valve. Bubbles were injected from five needles located near the bottom of the test section.

XVIII IMEKO WORLD CONGRESS Metrology for a Sustainable Development September, 17 – 22, 2006, Rio de Janeiro, Brazil IMPROVEMENT OF ULTRASONIC CROSS-CORRELATION MEASUREMENT OF GAS FLOW BY BLUFF BODY GENERATED VORTICES

Ultrasonic cross-correlation flow meters using natural turbulences in a fluid must be calibrated. The reason is that the most frequent components in the fluid are determined by this method deviating from the average flow velocity. The calibration characteristic is nonlinear and depends on the flow velocity and profile, respectively. This disadvantage can be avoided by small artificially generat...

Numerical simulation of transit-time ultrasonic flowmeters: uncertainties due to flow profile and fluid turbulence.

Flowmeter measurement using the ultrasonic transit-time method is based on the apparent difference of the sound velocity in the flow direction and in the opposite direction. This method gives a flow velocity averaged along a particular acoustical path. To convert this path velocity to a velocity averaged over the entire cross-section of the flowing medium, the knowledge of the flow velocity pro...
