Electronic remote water meter, not the conventional mechanical based water meter, by flow rate sensor technology, high accuracy, wireless remote reading by RF module
Description:
The electronic remote water meter developed by one fully new
concept technology: contactless electronic flow rate sensor. It is
patent protected in China.
Measuring principal 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
-Ad-hoc network
Applications:
Residential & domestic water measuring, office building water measuring
