ZG(S)-1 Series IC card prepaid gas meter/new gas meter
General
ZG(S)-1 series of IC card prepaid gas meters are suitable for measuring the flowrate of natural gas, liquefied petroleum gas, artificially gas, marsh gas, etc.
The meter has high accuracy measurement and long economic life. Apart from the original reading ability, it also has the following advantages: one particular card for each meter, display of gad volume, reminder of low voltage, protection at low voltage, reminder of insufficient credit, gas overdraft, illegal operation record, switching the valve off while electricity supply is cut off, display button, button to switch on valves, protection of card insert point, anti-magnetic attack, anti-disassembling meter and low power consumption. It is widely used for prepayment management in gas companies. The meter performance can fulfill OIMLR137-1&2 standard requirement.
