I. Introduction

The Remote Transmission Type Domestic Gas Meter is comprised of a common domestic gas meter and a flow rate relating signal acquisition unit, which converts the flow rate into switching signals to output. The switching signals match with the signal acquisition system, thus the gas consumption counting or fee charging without entering the house can be accomplished. Moreover the microcomputer networking fee charging management may be carried out.
This product and IC card system can also be combined into IC card gas meter. It is suitable for centralized management of gas metering in residential areas, office buildings, apartments etc. and is a ideal gas meter for property management in the residential areas.
