Example 1: channel drainage monitoring
The ultrasonic Doppler non-full pipe (channel) flowmeter consists of a transmitting/receiving integrated sensor, an ultrasonic liquid level meter and a signal processing and transmitting electronic unit.
The sensor is arranged in a pipeline (channel) to emit ultrasonic waves f1, the ultrasonic waves are emitted from the water to the water surface at a certain angle, and after the ultrasonic waves encounter suspended particles or bubbles in the water, the frequency of the ultrasonic waves is shifted and the ultrasonic waves are reflected to the transducer at the frequency of f 2. This is the doppler effect, and the difference between f2 and f1 is the doppler frequency difference fd. Let the fluid flow velocity be v, the ultrasonic sound velocity be c, and the doppler shift fd be proportional to the fluid flow velocity v. There are a lot of impurity particles and bubbles in the water, each reflecting particle corresponds to a doppler shift fd, and the flow velocity can be obtained by conversion, and the average flow velocity of these many particles is also the average flow velocity of the fluid. And (3) analyzing and separating the frequency of the interference signal through specific circuit design and software to obtain a real echo. In practice it is required that the liquid contains at least 100ppm of a solid suspension having a particle size greater than 50 microns.
The flowmeter firstly calculates the flow velocity V of a medium according to the Doppler principle, then a high-precision two-wire ultrasonic liquid level meter is used for measuring the liquid level height H of a pipeline, a transmitter can calculate the sectional area S of water flow according to the known channel width, and the flow velocity value V can be automatically corrected according to the height of the liquid level, so that the accurate flow Q is S V.
Example 2: pipeline drainage monitoring
As shown in FIG. 4, two acoustic wave transmitters (S) are usedAAnd SB) And two sound wave receivers (R)AAnd RB). Two groups of sound waves of the same sound source are at SAAnd RAAnd SBAnd RBRespectively transmitted therebetween. They are mounted along the pipe at an angle theta (typically theta 45 deg.) to the pipe. Since the acoustic waves traveling downstream are accelerated by the fluid and the acoustic waves traveling upstream are delayed, the time difference between them is proportional to the flow velocity. The flow velocity measurement can also be realized by sending a sinusoidal signal to measure the phase shift between two groups of sound waves or sending a frequency signal to measure the frequency difference.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the scope of the claims of the present invention.
