Description

LGV V-cone flow meter is the second generation inner cone flow meter. It is a good performance differential pressure flow meter developed by Dandong Top Electronics Instrument (Group) Co., Ltd in cooperation with Tianjin University. The unique support and taper angle design enables it to measure the flow rate of various medium such as gas, liquid and vapor under very short straight pipe section conditions. Features 1.LGV V-cone flow meter carries on a lot of experimental research according to different equivalent diameter ratio and different front and rear cone angles, and finally determines the optimal combination of front and rear cone angles under different diameter ratio, which makes the range ratio wider and the measurement accuracy higher. 2.The method of cone fixation with support is adopted, which makes the cone fixation very firm and reliable, and reduces the influence of cone vibration on measurement. At the same time, the influence of the front and rear support on the flow field is also fully considered. Ensure the measurement accuracy. 3.The influence of coefficient of expandability ε on gas flow measurement is fully considered in the design of LGV V-cone flow meter. The real flow experiment of expansion coefficient is carried out by using the standard device of gas flow rate of sonic nozzle with positive pressure method.
