Product Description：
This product is a remote reading water meter,which uses ultrasonic time difference method to measure water consumption. It has the features of measuring accurate and stable, high range ratio, ultra-low initial flow and pressure loss, no long-term wear error. The meter materials meet the sanitation standards of drinking water metering instruments and conform to ISO4064:2014 and other standards. Prepaid/postpaid can be switched. The water meter communicates with CIU via LoRa ; DCU uplink 2G/4G communication, downlink through LoRa, RS485 channels and water meter communication, the collected data can be connected to the customer system, DCU data reading, setting, recharge. Pre-pay/Post-pay can be switched. The company's system can also be used for meter reading and management functions.
