Multibeam ultrasonic flowmeters RUM

Flow meters ultrasonic multibeam RUM (hereinafter RUM or flowmeters) are designed to measure the volume and/or mass flow rate of liquid media.
The flowmeters are designed for use in systems of accounting and control of liquid flow in automatic control systems of technological processes.
The flowmeters can be placed indoors, outdoors in a wide range of climatic conditions, on fixed and mobile objects, in ship and industrial conditions.
The flowmeters can be used both in normal and explosive installations and premises in accordance with the normative and technical documents regulating the use of electrical equipment in hazardous areas.
For installation in hazardous areas the flowmeters are manufactured in explosion-protected version "intrinsically safe electric circuit" according to GOST 31610.0 (IEC 60079-0), GOST 31610.11 (IEC 60079-11) with marking 0?? ia IIB T6...T5 Ga or 0?? ia IIC T6...T5 Ga.....
