GENERAL Prepaid gas meter combines mechanical gas meter and electronic
measurement control circuit together, which perfectly maintains
high accuracy of mechanical meter and automatic management function
together. Holley’s intelligent gas meter has compact structure,
high tech components; and insures safely easy operation. The prepaid gas meter plays an important role in scientific gas
supply and automatically management field. Customer could easily
get the data of purchased gas or remaining gas by handling an IC
card. The prepaid gas meter applies to the measuring of manufactured gas,
natural gas, liquefied petroleum gas, marsh and so on. Steel case and Aluminous case for choosing.
