摘      要：In this article we have described the development of solar-powered gas metering units including modern ultrasonic and vortex flowmeters for volume and mass measurement of natural gas, associated petroleum gases, inert gases, oxygen, hydrogen, air, nitrogen, carbon dioxide and any other single and multicomponent gases that are not aggressive to the flowmeter materials. We have shown implementation of such units in the existing gas producing stations in the desert of Kara-Kum. Confirmed was the ability of our gas metering units to operate more than a year without network power supply and staff intervention. Also pictured was creation of telemetry system for collecting and transmitting metrological information, including gas flow rate, temperature, pressure, humidity to the central terminal. Different physical layers have been used to transfer data from the metering units, including radio channels at 433 MHz frequency between units and central station. This telemetry system implemented selfmaintenance and self-monitoring features, facilitating remote control of metering unit, so important in rigid conditions of solar-rich deserts and semi-deserts.
