Ultrasonic water meters and ultrasonic flowmeters are both ultrasonic instruments, so what is the difference between them? Because they measure the media is different, the instrument used is different, like ultrasonic water meter, it is a single application in the water medium, its principle is the same as the principle of ultrasonic flowmeter, ultrasonic flowmeter measurement range is relatively wide, it can measure the medium may be water, chemical liquid, oil, alcohol and so on all kinds of fluid measurement. Other functions are basically the same, which is the biggest difference between ultrasonic water meter and ultrasonic flowmeter.
Ultrasonic flowmeters are instruments that measure flow by detecting the effect of fluid flow on an ultrasonic beam (or ultrasonic pulse). According to the principle of signal detection ultrasonic flowmeter can be divided into propagation velocity difference method (direct time difference method, time difference method, phase difference method and frequency difference method), beam migration method, Doppler method, cross-correlation method, space filter method and noise method. This ultrasonic flowmeter is mainly composed of meter body, ultrasonic transducer and installation parts and signal processing unit, the general appearance of the market has a plug-in type, external clamped flowmeter, the transducer of the plug-in flowmeter directly and the measured flow body contact, and the transducer of the external clamped flowmeter is tightly installed in the pipeline wall through the coupling agent. External clamp-type (convenient) ultrasonic flowmeter in the implementation of pipeline flow measurement, its transducer is required to take different installation methods according to pipeline conditions, generally using direct projection method and reflection method more.
Ultrasonic flowmeter is generally divided into ultrasonic open channel flowmeter and pipeline flowmeter. Usually we use the ultrasonic pipe flowmeter, of course, the measurement medium is different, the name is different, such as ultrasonic flowmeter can also be said to be ultrasonic flow transmitter, the flow signal into the current signal output. Ultrasonic level meter can also be said to be ultrasonic level transmitter, the level information into standard information output.
Ultrasonic water meter is a full electronic water meter made of industrial electronic components based on the principle of ultrasonic time difference. Compared with mechanical water meter, it has the characteristics of high precision, good reliability, wide range ratio, long service life, no moving parts, no need to set parameters, arbitrary Angle installation, etc.
