Wireless digital water meter is developed from our patent technology electronic water meter. Automatic reading by wireless RF module through PDA or fixed network.
Description:
Wireless AMR water meter is the wireless automatic reading electronic water mete developed by one fully new concept technology: contactless electronic flow rate sensor. It is real electronic and digital, thus provides high accuracy measuring of the water consumption.
Electronic flow rate sensor 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 an advanced specially designed electronic circuit, the CPU of electronic circuit calculates signals, then reaches the intention of metering. Such technology makes ElectroAMRTM resistant to wear and impurities in the water.
Also It is automatic reading by wireless RF module. 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, which brings much lower cost and higher efficiency to water company and water utilities.
Applications:
Wireless digital water meter is used for domestic and residential measurement of cold water consumption in household and high-floors flats as well as industry.
