Overview

   WYQ-CG-L-G1.6/2.5/4 series wireless IC card remotely-reading diaphragm gas meter uses IC card to realize its prepaying, automatic reading, and wireless remote monitoring function. These gas meters belong to the new generation smart gas meter. And they can be broadly used in natural gas, coal gas, liquefied petroleum gas, and other kinds of combustible gas. And they are ideal measuring instruments for modernized gas management.

   WYQ-CG-L-G1.6/2.5/4 series wireless IC card remotely-reading diaphragm gas meter is designed with a microcomputer and a special control computer program to realize its automatic data processing function. Fuel gas administrative departments pre-sell the gas through the Pre-sell Computer System. Fuel gas administrative departments also can save the number, the wireless communication address, the wireless communication parameter, meter constant, mechanical measuring initial value, the user’s name, real address and other information.

Technical Function

AS the prepaying storage media, IC card have a lot of features such as magnetic field resistance, scratch resistance, anti-counterfeiting, high confidentiality, high storage capacity, high reliability, and so on.

1.       Wireless IC card remotely-reading diaphragm gas meter have the function of anti-gas stealing, and anti-detaching.

2.       Wireless IC card remotely-reading diaphragm gas meter have the length 6 LCD displaying to display the gas using information, and it also can prompt Status Information.

3.       Through wireless IC card remotely-reading diaphragm gas meter people can set user’s password and wireless communication address. The specific address is connected to the specific gas meter. It is no use for the gas user to exchange a IC card with others or change the wireless communication address. This is also called “one card one gas meter”.

4.       This series gas meters are built with double transducers technique which improved the meter’s accuracy of measurement.

5.       Wireless IC card remotely-reading diaphragm gas meter has gas selling manage system, and AMR system. There is no need for the gas selling department to send person to read the meter. The gas selling department can monitor and statistics the user’s using condition in any time. It can realize the automation and modernization of the gas selling.

6.       Wireless IC card remotely-reading diaphragm gas meter uses both inside battery and outlay battery power-supply system. The long-range control part can keep on working when the user have not insert the outlay battery or the outlay battery is battery low.

4.Wireless IC Card Remotely-reading Domestic Gas Meter’s Meter Reading System

Wireless IC card remotely-reading diaphragm gas meter’s meter reading system can realize the functions of prepaying, real time data collecting, valve remotely-opening and valve remotely-shutting. Through the system, the gas company also can change the gas price to avoid the gas company’s loss which is brought by the gas price rise.

PDA+Bluetooth collector automatic data acquisition method: The user downloads the gas users’ information from the gas company severs firstly. Then PDA collects the meters’ information through Bluetooth collector and transmits the data collected to the gas company server.

GPRS automatic data acquisition method: Install a wireless collector in the meter. Through mobile information network, the collector sends the data collected to the gas company sever directly.
