PDA reading water meter is one new technology electronic AMR water meter. It is wireless read by PDA reader.
Description:
The PDA reading water meter developed by one fully new generated
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.
PDA reading water meter is done by hand PDA reader, walk-by or drive-by
Applications:
Residential water meter, domestic water meter, irrigation water meter
