Automatic meter reading water meter is one type automatic reading electronic water meter, not the conventional mechanical based water meter, including size DN15 & DN20, for domestic & residential installation.
Wireless AMR by RF module, automatic meter reading by PDA or fixed network.
Description:
Automatic meter reading water meter is one type automatic reading
electronic water mete developed by one fully new concept
technology: contactless electronic flow rate sensor. It is patent
protected in China.
It’s working 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 metering. At the same time control circuit converts metering data to computer by wireless RF module, so realizes wireless remote transmission and automatic meter reading.
Radio frequency of the water meter as: 430~440MHz, 470~510MHz, 868~870MHz, 902~928MHz or customized
Automatic reading has two solutions: Hand PDA reader, walk-by or drive-by & fixed network
Applications:
Automatic meter reading water meter is used for measurement of cold
water consumption in household and high-floors flats as well as
industry, it is IP68, also can be placed inside bath room and water
well as well.
