The development of radio and 3g based telemetry system for the remote gas accounting and control nodes

Abstract

In this article we have described the use of vortex and recently developed ultrasonic flowmeters with high dynamic range of 1 to 1500 for industrial applications. Its software and the software of corresponding computing device is able to avoid gas leakage, to minimize energy consumption and to save human resources while maintaining metrological data. Described is the low power consumption that makes it possible to use this ultrasonic flowmeter in hard remote environment without direct management for a period of several months. Shown is the new telemetry system that was developed to unite flowmeters in the severe conditions of the desert with power supply problems and low GPRS signal quality. Experiments held in Turkmenistan have shown that device indications didn’t drift and remained stable during the year, that is a great advantage in comparison to rotary and turbine flowmeters. Also described is the mobile ultrasonic calibration stand that uses the same physical principles and similar software. Outlined is the usage of modern wireless technologies to collect and transmit metrological data.
