9, battery-powered ultrasonic flowmeter: use a lithium battery-powered integrated ultrasonic flowmeter is suitable for the occasion without mains supply, a battery can use for ten years, with a variety of measurement functions.
Pipe-stage ultrasonic flowmeter transducer and measure the tubes one, to solve a problem posted outside the flowmeter in measurement. And accuracy are higher than other ultrasonic flowmeter, but also at the expense of outside - attached ultrasonic This advantage continues to flow meter installation, pipeline installation requires cutting transducer.
Plug-in ultrasonic flowmeter Intermediate between the above two. On the installation can continue to flow, the use of specialized tools on a water pipe drilling, the transducer is inserted into the pipeline, the installation is complete. Since the transducer in the pipeline, transmit its signal, accepted only after the measured medium, rather than through the wall and the lining, so the quality is not measured and pipe lining material restrictions pipe.
3 ultrasonic flowmeter selection
Ultrasonic flowmeter In addition to these types, in recent years and the emergence of digital circuits using digital ultrasonic flowmeter, the transducer and the converter to do with the integrated ultrasonic flowmeter, and so on. The face of numerous types of ultrasonic flowmeter The user needs a reasonable selection to the actual situation and measurements.
3.1 Doppler ultrasonic flowmeter
Can only be used to measure the reflected ultrasound signal containing appropriate particles or bubbles of fluid, such as liquid plant emissions, untreated sewage, magazine content and stable plant process fluid, etc. is to be noted that it measured media more stringent requirements, that can not is clean water, while acrobatics content should be relatively stable before they can properly measure, and instruments from different manufacturers to test performance and the requirements of manufacturers are not the same. Select this type ultrasonic flowmeter that is, to know what the measured medium, but also for the selected ultrasonic flowmeter performance, accuracy and measured medium requires a deeper understanding.
3.2 portable ultrasonic flowmeter
Suitable temporary measure, mainly for running state other flow meters have been installed on the proof pipes, were at that time the fluid flow balance test, checking the pipeline within a region, etc. If you do not make a fixed installation, and for these purposes, selection of portable ultrasonic flowmeter is both convenient and economical.
