ultrasonic water meters
Household water is the basis of the people's life, if the water meter used for flow metering is broken, life will be very troublesome. What are the common faults of ultrasonic water meters? Will there be errors in current metering payment?Let me answer for you the ultrasonic water meter common fault. And a brief talk about ultrasonic water meter broken how to do!
First, manufacturer inspection: ultrasonic water meter common fault analysis.
1.If the sensor at the inlet and outlet of the water meter fails, it may affect the accuracy of flow measurement and even damage the meter. It is recommended that the inlet/outlet sensors be replaced or reinstalled.
2.Ultrasonic water meters are based on ultrasonic flow measurement technology, which works in much the same way as ultrasonic flowmeters (see this chapter article to show you how ultrasonic flowmeters detect flow). So when installing an ultrasonic water meter, you need to pay attention to the direction of water in and out. If the inlet end and outlet end of the pipe section are connected in the opposite direction, it will lead to countercurrent failure. It is recommended that the inlet and outlet ends of the ultrasonic water meter be changed immediately.
3. The instantaneous flow can be clearly observed through the screen of the ultrasonic water meter. If the instantaneous flow of current is too high, it will lead to overrange failure. This can be due to incorrect control of the water valve at the water inlet of the meter. It is recommended to adjust the water valve at the water inlet to reduce the flow or replace the ultrasonic water meter with the appropriate range.
4. If there is no water in the measuring section of the ultrasonic water meter or the section is not filled with water, it will lead to the failure of the air pipe. It is recommended to fill the ultrasonic water meter pipe section with water and remove air bubbles in the pipe section.
5. The above four points are the common causes of failure in the flow measurement process. There are some problems in the flow conversion and data storage of ultrasonic water meters. For example, memory impairment caused by EROM memory impairment. Since EROM memory is built into the circuit board, this recommendation can be addressed by replacing the circuit board.
6. A low battery voltage or poor connection can also cause a battery failure. It is recommended to check whether the connection plug of the ultrasonic water meter control box is connected; If the battery voltage is too low, you can replace the battery.
