Digital remote reading water meter is based on our real digital water meter developed by flow rate sensor technology, high accuracy & Class C. AMR via RF
Description:
Digital remote reading water meter is developed by one fully new
concept technology: contactless electronic flow rate sensor. Such
technology makes the water meter to be real digital and electronic.
Measuring 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.
Digital AMR water meter is compatible with two automatic meter reading solutions
-Hand PDA reader, walk-by or drive-by
-Ad-hoc network
Digital remote reading water meter applications:
Residential water meter & domestic water meter
