Steel Case Household Diaphragm Prepaid Gas meter with IC Card G1.6/G2.5/G4
General Description
IC Card Household Diaphragm Gas Meter is applicable to metering
urban pipeline gas, natural gas, liquefied petroleum gas, and other
non-corrosive gas, etc.. Parameters of the gas meters accord with
the requirements of <GB/T6968-2011 diagram gas meter>.
Use the logic encryption card ( called IC card) as the information
carrier. The data is read from the IC card and be exchanged by
control module .And the meter information like gas volume and
working status will be writen to the IC card and be feedbacked to
the gas selling management system by IC card. When we use the gas ,
the control module will receive the signal from the collector and
will make some measurement process to the gas volume information.
When the Residual gas volume reach to 0, control module will send
the order of closing the valve to stop the gas using until the
customer purchase the gas again. This is the management of prepaid.
Structural Features
Consist of basic gas meter and electronic controller. Electronic
controller consists of control module, signal collector and valve
actuator.
1. Steel Case, independent core with high sensitivity and accuracy,
diaphragm type structure, advanced process, big character wheel,
counting device.
2. Prompt function When remaining gas or battery capacity is lower
than the pre-set value, it will prompt consumer to purchase or
replace the battery in time.
3. Alarm The meter will detect and record the magnetic disturbance,
non-metering, valve stoppage, low battery etc. automatically and
there will be related alarm symbol displayed on LCD, all the events
record could be transferred to master station through IC card.
