DN20 AMR water meter is not the conventional mechanical-electronic water meter, but is real electronic water meter produced by flow rate sensor technology, high accuracy & Class C.

Wireless AMR by RF module

 

Description:

DN20 AMR water meter developed by one fully new innovative 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 wireless RF module, so realizes wireless remote transmission and automatic meter reading.

Wireless Electronic AMR water meter is compatible with two automatic meter reading solutions: Hand PDA reader, walk-by or drive-by & fixed network.
