What is the difference between the installation of large-diameter water meters and ordinary water meters
There are many kinds of water meters, not only the water meters used in our homes, but also other types of water meters. Today we will learn about large diameter water meters. Let's see what is the difference between the large diameter hot water meter and the water meter we usually use. Next, let's take a look at how to install the large-diameter water meter correctly:
1. In order to facilitate the maintenance of the water meter, it is recommended to install valves at the appropriate upstream and downstream positions.
2. In order to compensate for the errors in the installation of the water meter and facilitate disassembly and assembly, it is recommended to install expansion joints with corresponding diameters downstream of the water meter.
3. The water meter dial should be installed horizontally upward. The direction of the arrow of the watch case should be consistent with the direction of the water flow in the pipeline. A flow straightening device or a straight rectifying pipe section should be installed upstream of the large-diameter hot water meter. The length of the straight rectifying pipe section should be greater than 5 times or 10 times the water meter caliber.
4. The user of the water meter is not allowed to disassemble and assemble the control part of the water meter and the valve at will. If you encounter problems, you can contact the relevant departments to solve them.
5. The newly installed pipeline should first remove the stones, sediment and other debris in the pipeline before installing the water meter to prevent the water meter from being damaged or malfunctioning. It is recommended to install a filter.
6. Large-caliber hot water meters should be protected against exposure to sunlight and freezing.
7. When selecting a water meter, the frequently used flow rate of the pipeline should be close to or less than the common flow rate of the water meter, and the diameter of the water meter cannot be determined simply by the diameter of the pipe.
8. The large-diameter hot water meter should not be subjected to excessive stress caused by the pipe, and the water meter should be installed on the base or bracket when necessary.
9. The water meter is far away from the vibration source, and the vibration will affect the accuracy of the water meter.
