A Comparative Study about Pressure Loss of Vortex Flowmeter and Orifice Plate FlowmeterJIA Yun-fei, ZHANG Tao, ZHANG Qing-peng School of Electrical Engineering ＆ Automation, Tianjin University, Tianjin 300072, ChinaAbstract:Pressure loss of vortex flowmeter is investigated and the result of experiment is compared with that of orifice plate flowmeter. Some researchers have studied pressure losses of vortex flowmeter and orifice plate flowmeter, because they are widely used. But the results of study are not appropriate because of without an equal effective flow area about these two different flowmeters. Pressure losses of them are compared at a same flow area. As a result, their pressure loss ratio is not so much as given in some papers.[著者文摘]
