Product Description：
This product is a vertical spiral-wing type large-diameter water meter.It is suitable for water measurement in scenarios with relatively stable flow, such as factories, mines, and water supply trunk lines. It realizes water volume measurement, water volume reporting, abnormal reporting, valve control, etc., and can achieve the prepaid function of "pre-purchase and then use" for users through the water sale system. It can flexibly preset various functions: remote recharge, valve closing, valve opening, reset, and theft water clearing, etc. Prepaid and postpaid can be switched. Information transmission between users and the computer of the power supply department is realized through media such as IC cards, 2G/4G, LoRa, and RS485, thus meeting the modern scientific management requirements of the water supply department for users to be effective and timely.
