Unattended Trading Metering Station
信息来源:  发布时间:2015-08-27  阅读次数:185

The unattended trading metering gas station of Northwest Sichuan Gas Mine is located at a distant region, and most field instrument, pipelines, and metering devices are assets of the consumer. The daily gas consumption ranges from hundreds to tens of thousands cubic meters. Due to the low consumption, the field workers are barely present on site; therefore, the delay of default locating may affect the precision of trading metering.
The Guoguang LWJD acquires the field data and transmits them to the management center by means of GPRS or DDN
