Over the years, with the rapid development of new technologies in our country and the country’s increasing efforts to save energy and reduce emissions, our company has also followed the pace and adopted new technologies. Among them, ultrasonic flowmeters have been widely used in heating pipelines. Ultrasonic flowmeters are easy to install, simple and convenient, and have no mechanical loss and long life. Especially portable ultrasonic flowmeters are easy to install, and only attach probes outside the tube to measure flow. Therefore, the pipeline does not need much treatment (local derusting and paint removal at the measuring point), and there is no pressure loss for the sealing of the pipeline. Compared with other online instruments, there is no need for pipe breaking treatment, no turbulence equipment, mechanical rotating equipment, and no shrinkage. Diameter, drainage orifice, etc., are easy to install, and reduce the risk of leakage. They have huge application potential in the heating industry.

After actual use, the portable ultrasonic flowmeter has a certain reference validity for the measurement of the flow adjustment data of the heating pipe network. Its value is larger than the fixed flowmeter measurement data due to installation and debugging in different environments, mainly because the measurement value has a meter error. However, its value has certain rules. If you want to exert its efficiency, it should be combined with the on-site working conditions. First, there is a fixed flow meter on the site. The preliminary data collection and recording work should be done. When the flow rate changes suddenly, the portable ultrasonic flowmeter should be used for timely Check and compare the data, find out the cause of the sudden change in flow, and find out whether the meter is malfunctioning or the flow has indeed changed; secondly, for the users who have no fixed flowmeter at the temporary measurement point, try their best to meet the equipment measurement and installation requirements on site, and minimize Human factors interfere, and the installation of transducers is the main key factor affecting the accuracy of measurement. Therefore, the field application should be adjusted and installed according to the environment to ensure that the location is selected, installed, and measured. The effectiveness of the portable ultrasonic flowmeter depends on the operator's judgment and analysis based on the on-site situation, and the accumulation of experience in man-machine cooperation is required.
