LGV V type internal cone flow meter is the second generation of inner cone flow meter. It is a kind of high performance differential pressure type flow measuring instrument which is developed jointly by Dandong Top Electronics Instrument (Group) Co. Ltd. and Tianjin University. The unique support body and variable angle design, can make it measure medium flow under the conditions of short straight pipe. The measured mediums can be gas, liquid and steam in metallurgy, chemical industry, chemical fertilizer, chemical fiber, oil, natural gas, electric power, hydraulic power, and other industrial enterprises. It has characteristics such as strong cone, short straight pipe, high measurement precision, wide range ratio, small pressure loss and low installation cost, etc. As a breakthrough in the field of flow sensor technology in recent years, it makes up for the structure defects of the orifice, nozzle, venturi tube and other standard throttle device. This flow meter has broad market prospects.
