Performance feature: 1.It is accurate and reliable. Mechanical and electronic computation display. 2.The output part of water meter adopts a bi-stable design against magnetism, therefore the meter will not send wrong data or neglect any pulse. 3.The electric control unit makes of MCU with extremely low power, which has a powerful function, high reliability and ability to resist inferences. 4.Good lithium battery, can work for 6 yeas. 5.Self-checking function and the entire meter utilizes an airproof insulation design. 6.One card for one meter, and use a unique encrypt manner to wholly resist fake cards. 7.Make of stainless steel ball valve with no voltage loss, low power and low failure frequency. 8.There is an embedded live clock. It enable frozen data and ladder water charge.
