Full Plastic Electronic Water Meter Domestic For Househould , Industry
Quick Detail:
Size :DN15 (3/4”) & DN20 (1”)
Technology:flow rate sensor technology
Full electronic & digital (not mechanical-electronic)
Applications:
Full plastic electronic water meter domestic for measuring of
cold water consumption in household and high-floors flats as well
as industry such as drinking, machinery and irrigation.
Description:
The electronic water meter developed by one fully new concept technology: contactless electronic flow rate sensor. Current available models are DN15 & DN20 for residential.
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.
