Over the years, with the development of new technologies in China and the country to increase energy conservation and emission reduction efforts, our company also follows the pace, absorb the use of new technologies, of which ultrasonic flowmeter in heating pipeline measurement has been widely used. Ultrasonic flowmeter has the advantages of easy installation, no mechanical loss and long life, especially the portable ultrasonic flowmeter is easy to install, and it is only attached to the probe outside the tube to measure the flow rate. Therefore, the pipeline does not need too much treatment (local rust removal and paint removal at the test point), there is no pressure loss on the pipeline sealing, compared with other online instruments, no need to break the pipe treatment, no spoiler equipment, mechanical rotation equipment, no need to shrink, drainage hole plate, etc., easy installation, leakage hazards are reduced, and it has great application potential in the heating industry.
After the actual use of portable ultrasonic flowmeter for the heat supply network flow regulation data measurement has a certain reference effectiveness, its value by different environment installation and debugging than the fixed flowmeter measurement data error, mainly because its measurement value has table error. But its value has a certain rule, if you want to play its efficiency should be combined with the field conditions, first, the site has a fixed flow meter should do a good job of the early data acquisition and record work, when the flow mutation occurs, to use the portable ultrasonic flow meter to check the comparison data in time, to find out the cause of the flow mutation, to find out whether the meter failure or the flow did change; Second, for the temporary measuring point without fixed flow meter users on-site to meet the equipment measurement installation needs, as far as possible to reduce human factors interference, the installation of the transducer is the main key factor affecting the measurement accuracy, so the field application should be adjusted and installed according to the environment, to ensure that the location is good, installation is good, measurement. The use effect of portable ultrasonic flowmeter depends on the operator's judgment and analysis of the field situation, and the accumulation of man-machine cooperation experience is required.
