2. Design of the flowmeter to measure the volumetric flow of oil in telemetry divisions of pipeline. The flowmeter has explosion proof marking 1ExibIIBT3 X and meets the requirements of GOST 22782.5 and GOST 22782.0. It can be installed in explosive zones of premises and outdoor locations. The flowmeter can be used to control technological processes in metallurgical, chemical and other industries; in water supply and drainage systems or during the flow determination of water, acids, alkalis, oil, and petroleum refinery products, and other liquids.
