In the process of using the ultrasonic water meter, there will be more or fewer failures due to some reasons. Today, we will share with you how to judge the root cause of ultrasonic water meter failure and deal with it simply.
Causes and solutions of common faults:
1. The ultrasonic water meter rotates when no water is used:
Cause of Issue
·The pressure fluctuation in the pipe network is too large;
·The distance between the ultrasonic water meter and the main pipe is too close;
·The installation of water meters is too concentrated, which affects the water hammer effect of nearby users;
·There is water leakage in the pipe network behind the meter;
·The one-way valve of the special water-saving meter is not installed or the one-way valve is stuck and cannot be reset;
·There is a dead leg in the pipe network behind the instrument, forming an air column.
Solution: Swirling is a common area phenomenon that may be caused by excessive local water pressure fluctuations. It is recommended to install a flexible check valve or replace a water meter with low sensitivity.
Check whether the rotation of the water meter is individual or several times; if it is non-intermittent and uniform rotation, it is usually because of the leakage of the pipe network behind the ultrasonic water meter; if it is intermittent rotation, please check whether the ultrasonic water meter is installed too close to the main pipe or not Centralized installation, whether there is a pipe network behind the water meter to form an air column.
If a water-saving meter with a check valve rotates, the air in the pipe network behind the meter should be bled out and the check valve should be cleaned of debris. After the above treatment, if the ultrasonic water meter is still rotating at a constant speed, it indicates that the pipe network behind the water meter is leaking.
2. The dial surface is black:
The cause of the failure: poor water quality, and dirt accumulation; water contains chemicals that can react with the ink; the quality of the ink itself is defective.
Solution: install a filter before the ultrasonic water meter pipe. Clean the surface and recalibrate or replace it with a new one.
The above are the reasons for the failure of the ultrasonic water meter and some operations for simple treatment. If you have other questions, please feel free to contact us for communication and discussion.
