Utility Electronic Water Meter For Machinery, Instrument Water Consumption Measuring
Quick Detail:
Accuracy: Class C & D
Medium temperature:T30
Size: DN15 & DN20
Applications:OIML Utility electronic water meter for machinery,instrument water consumption measuring
Description:
The digital 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.
