What influences the accuracy of ultrasonic water meter measurement?

Ultrasonic water meters are already an indispensable part of smart modern cities. So do you know what factors affect the accuracy of ultrasonic water meters? What is the solution?

The first point is that there are impurities in the ultrasonic water meter pipe. The solution is, before installation, be sure to clean the impurities in the system pipes, such as hemp, sand and gravel. If they are not cleaned, it will affect the measurement of the ultrasonic water meter, and even cause the water meter to malfunction; 

Two points, the water meter is installed in the wrong direction. The solution is to see clearly the direction indicated by the arrow of the ultrasonic water meter before installation, and the direction of the water flow should be consistent with the direction indicated by the arrow of the ultrasonic water meter during installation.

 The third point is that there are not enough straight pipe sections before and after the meter. The solution is to leave 10 times the DN in front of the ultrasonic water meter and 5 times the DN behind the meter. 

Fourth, the over-range cannot be measured normally, which is different. The common flow rate of the caliber is different. When purchasing a large-caliber ultrasonic water meter, it is necessary to know whether the diameter of the pipeline is reduced.
