Description
Technical field
The utility model belongs to the flow detection technical field, particularly a kind of device for detecting ultrasonic wave flow.
Background technology
The measuring ultrasonic wave flow technology is widely used at present in the industrial process parameter detecting.The ultrasonic flow measurement measurer has or not pressure reduction, noncontact, do not destroy the flow field, easy to install and measuring accuracy is difficult for the advantages such as affected by environment, and can be to having corrosivity or not having the rate of flow of fluid of electric conductivity to measure.Along with the develop rapidly of electronic technology and the continuous enhancing of microprocessor processes ability, the measuring ultrasonic wave flow technology has extraordinary application prospect.Therefore, a kind of easy to install, stability of utility model and the high device for detecting ultrasonic wave flow of accuracy have great superiority and market potential.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of easy to install, stability and the high device for detecting ultrasonic wave flow of accuracy.
The technical solution of the utility model is achieved in that this ultrasonic wave flow measuring device comprises ultrasonic transmitter, ultrasonic receiver, and ultrasonic transducer, oscillator, timer, controller, Single Chip Microcomputer (SCM) system, keyboard input and LCD show that nine parts form.The input end of Single Chip Microcomputer (SCM) system output terminal access controller.Controller output end access ultrasonic transmitter input end, the input end of the output terminal access ultrasonic transducer of ultrasonic transmitter, the input end of the output terminal access ultrasonic receiver of ultrasonic transducer.The output terminal access controller input end of ultrasonic receiver.Controller output end connects the input end of timer.Oscillator output end connects the input end of timer.The input end of the output terminal access Single Chip Microcomputer (SCM) system of timer.The input end of keyboard input access Single Chip Microcomputer (SCM) system, Single Chip Microcomputer (SCM) system output termination LCD shows input end, in order to the display measurement result.
By same device for measuring ultrasonic wave flow is installed in fluid line both sides, single-chip microcomputer produces pulse by controller and launches ultrasound wave to ultrasonic transmitter, ultrasound wave is by the following current fluid, be converted to echoed signal at opposite side by ultrasonic transducer, return by ultrasonic receiver afterwards and receive.Ultrasound wave is in the fluid that flows, the downbeam acoustic wave propagation velocity can increase, and countercurrent direction reduces, and same propagation distance just has the different travel-times, utilize the difference of following current ultrasound wave time and the relation between the detected fluid flow velocity just can try to achieve flow velocity, thereby be converted into flow.Ultrasonic signal is processed by controller, by the count value of counter generation time, thereby obtains the transmission time of ultrasound wave in fluid.Oscillator provides time reference to counter.Just can calculate fluid in ducted speed by certain algorithm afterwards.And then can calculate flow.
Advantage of the present utility model: this device is easy to install, stability and accuracy high.
