Know More >
By using ultrasonic measurement technology, ZLINK residential ultrasonic water meter is a static water meter with excellent performance for residential applications. The meter starts metering with ultra-low starting flow: down to 0.001m³/h and wider measurement range of Q3/Q1= R400/R500, which allows for long-term stable and accurate metering of household water consumption. Our meters integrate a wide range of communication technologies, such as RS-485, RF, M-bus, NB-IoT and STS prepaid functions, to easily adapt to various application scenarios.
ZLINK RESIDENTIAL is a static water meter operating on ultrasonic measurement technology for residential application. ZLINK performs accurate metering of water consumption with long-term stability. ZLINK is integrated with a wide range of IoT technologies to fit various application scenarios, which paves the way towards intelligent water utilities and smart city.
