ISO 4064 Class C Electronic Water Meter Domestic For Garden House , DN20
Quick Detail:
size :DN15 (3/4”) & DN20 (1”)
technology:flow rate sensor technology
irrigation water meter
Accuracy:Class C
Pressure grade:MAP10
Protection grade::IP68
Temperature: T30
Description:
The digital water meter developed by one fully new concept
technology: contactless electronic flow rate sensor. It is patent
protected in China. It has available sizes of DN15 & DN20.
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.
Applications:
The domestic electronic water meter is used for measurement of cold water consumption in household and high-floors flats as well as industry such as drinking, machinery and irrigation.
