Advantages of Ultrasonic Water Meters
◆ Battery power detection: When the voltage is insufficient, it will be displayed on the LCD screen and can be uploaded to the management system through remote transmission
◆ Flow signal detection: When there is no water in the pipeline and no signal from the transducer, the system will automatically prompt, store error information, and give an alarm.
◆ Pipe burst detection: If the water meter detects a large flow for more than half an hour, the system will automatically prompt, store error information, and give an alarm.
◆ Valve abnormality detection: When the valve switch is abnormal during use, such as the switch is not in place, cannot be opened, or cannot be closed, the system will automatically prompt, store error information, and give an alarm.
◆Pipeline leakage detection: The flow signal continues to run for a long time, indicating a continuous long-term movement of water flow. It may be that the toilet and faucet are not closed properly, causing water leakage. The system automatically prompts, stores error information, and gives an alarm.
◆Water flow direction detection: There are arrows on the water meter body to indicate the installation direction and water flow direction, but the water meter is installed reversely due to negligence or other reasons during the actual installation. This means that when the direction of the arrow is reversed, the system will automatically prompt, store error information, and give an alarm.
