What Should Be Paid Attention to In the Installation of Ultrasonic Water Meters
Ultrasonic water meters can be divided into tube type, clip-on type, and plug-in type. No matter which type of ultrasonic water meter it is, it must be installed according to the installation requirements of ultrasonic water meters. Let's look at the ultrasonic water meters. installation requirements.
The installation of the ultrasonic water meter must pay attention to whether the diameter used is in line with the actual flow of the pipeline. Usually, the diameter of the ultrasonic water meter must take the pipeline flow data as a reference, which can be slightly smaller than the working flow of the ultrasonic water meter. However, such an ultrasonic water meter should not be selected from the diameter of the pipe. When installing, just follow the arrow and the direction of the water flow. In addition, after the installation is completed, attention should be paid to such details, especially the installation of the ultrasonic water meter in the straight pipe section. Due to the installation position of the ultrasonic water meter and the state of the measured pipeline, the measurement accuracy is affected to a certain extent. Therefore, under any site conditions, the longer the straight pipe section before and after the installation point, the better the installation point must be at least 10D on the upstream side and 5D on the downstream side.
To prolong the life of the ultrasonic water meter, try to avoid exposure to the sun, flooding, etc. at the installation site, so as to facilitate future meter reading or disassembly. It is best to clean the pipeline in the installed pipeline before construction, so as to avoid failures, and it is also required to install a water quality filter to better protect the ultrasonic water meter. Such an ultrasonic water meter is powered by a battery, so as long as the battery displays an alarm, or it has been used for 8 years, it needs to be inspected by special department personnel, so these problems need to be paid attention to during installation.
During the installation of the ultrasonic water meter, it is not only necessary to install a rectifier to avoid the eddy current phenomenon, but also the water outlet downstream of the water meter must be a little higher than the water meter, so that the measurement can be more accurate. For better installation and use, it is very necessary to install valves, that is, it is best to install valves upstream and downstream. This is conducive to the replacement and maintenance of the water meter in the future.
