Flow Restriction Device
As a secondary energy source, industrial steam is widely used. The accurate measurement of industrial steam has very important economic significance, and is also an important link to carry out energy saving work. In petroleum, chemical industry, light industry, metallurgy, textile, food, medicine and other industrial fields there are a large number of industrial steam measurement problems, especially the implementation of the central heating policy, it is urgent to solve the problem of accurate and reliable measurement of large pipelines and large flows of industrial steam. In order to meet the needs of industrial production, our factory produces LBJ series large diameter large flow metering devices (hereinafter referred to as devices). Applicable pipe gauge DN50-600, wide measuring range, comprehensive compensation, accurate and reasonable reading, is the current domestic effect of the best flow metering device. The device is mainly applicable to the industrial measurement of saturated steam, superheated steam, compressed air, mixed non-flammable and explosive gas and hot water, and the flow measurement, display, measurement and online automatic control of the production process can be used.
Main features of MTLG orifice flowmeter
