Remote Reading Residential Water Meter Electronic Class C , 3500mAH
Quick Detail:
Type: multi-jet velocity water meter
Flow range:0.025m3/h~4.0m3/h
Applications:Residential water meter, home water meter, domestic
water meter , irrigation water meter
Accuracy:Class C

The electronic remote reading water meter is not the conventional mechanical with electronic device water meter, but real electronic developed by flow rate sensor technology. Remote reading by Wireless RF module.
Description:
The electronic remote reading water meter developed by one fully
new innovative technology: contactless electronic flow rate sensor.
It is patent protected in China.
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 measuring.
The electronic remote reading water meter is compatible with two automatic meter reading solutions: Hand PDA reader, walk-by or drive-by & Ad-hoc fixed network
Applications:
Residential water meter, domestic water meter, irrigation water meter
