IC card gas meter
IC card gas meter deemed as the smart measuring instrument based on the diaphragm gas meter, with installing controlling valves, electrical controls and IC card operation system., which remains metering accuracy of mechanic meters and at the same time realizes automated management. The IC card gas meter, with compact structure and advanced technology, is convenient to operate and reliable in usage.
IC card gas meter is a main device which helps city gas companies and gas users realize the scientific and automated management of supply and use. The IC card has prepaid function and the credit and surplus credit can be displayed through the LCD. IC card gas meter is applicable for the metering of artificial coal gas, natural gas, and liquefied petroleum gas
