The electronic water meter developed by one fully new concept technology: contactless electronic flow rate sensor. It is patent protected in China.
It’s working principle as:
When water pass through the inner chamber of water meter, the impeller with magnet ring rotates, it couples with the electronic flow rate sensor which inside movement component embedded magnet ring by no-contact condition and they rotate synchronously. Also electronic flow rate sensor inside has element with stored electric field energy, the electric field changes together with the rotation movement, so that sensor element gets the accurate electronic signal and it connects signal with control circuit, the CPU of control circuit calculates signals, then reaches the intention of metering. At the same time control circuit converts metering data to computer by M-Bus (RS-485) protocol, so realizes remote transmission and automatic meter reading.
The electronic water meter is used for measurement of cold water consumption in household and high-floors flats & office buildings as well as industry.
Residential water meter, domestic water meter, irrigation water meter
