Manufacturer of smart prepaid ultrasonic water meter

Prepaid ultrasonic water meter is a new type of water meter that combines conventional ultrasonic water meters with intelligent locking valves. The measuring pipe section adopts an integrated design of instruments and valves, with a compact structure. It can communicate with other devices through wired or wireless interfaces, support IC card prepaid mode, and can also remotely control switch valves as needed, greatly facilitating the management department’s statistics and management of user water consumption.

Prepaid ultrasonic water meter features:

1. Equipped with built-in valve, integrated meter and valve, fully wrapped structure, anti damage
2. It has self diagnostic function, flow sensor fault alarm, temperature sensor fault alarm, measurement over range alarm, battery undervoltage alarm
3. Our company’s * * flow measurement method (authorized for invention * *) and intelligent data correction technology have been applied, with high measurement accuracy and stability. 4. Equipped with a built-in battery, it can meet the current requirements for valve operation. The entire instrument can meet a service life of (6+1) years
4. Equipped with photoelectric interface and handheld infrared meter reading tool, capable of on-site reading
5. Support card swiping, pre charging, and remote control of valve management system

IC card prepaid ultrasonic water meter

IC card prepaid water meter is a high-tech electromechanical integrated intelligent instrument composed of advanced microcomputer control technology as the core and smart card as the information transmission medium. It has dual functions of mechanical counting and electronic counting, mainly composed of smart card reader/writer, low-power microcomputer, innovative new motor valve, flow acquisition and corresponding circuit. While maintaining the characteristics of traditional mechanical water meter, it also has intuitive electronic display. It has the advantages of advanced design, high technological content, complete functions, accurate measurement, reliable performance, small size, intuitive display, exquisite appearance, and convenient installation and use. It is suitable for the measurement and charging of tap water for urban residents, avoiding the occurrence of water theft, leakage, and leakage. Through electronic billing, it achieves the goal of water conservation and scientific management while changing the traditional urban water supply management method from “use water first, pay later” to “pay first, use water later”, improving the modern management level of the water supply industry. At the same time, it facilitates user use and avoids the inconvenience caused by meter checking and charging to users.
