最近,交通部上海船舶运输科学研究所,应用由西德Kampf-Remmers公司引进的空泡水筒(1984年产品)完成了计量标定海流计技术条件的可行性论证。“空泡水筒”的筒体由不同横截面形状的不锈钢质管子构成,50吨纯净水由水筒底部的循环水泵驱动使其循环于筒内。水筒的转弯处有导流片,从而避免水流转弯时产生旋涡,水筒的工作段前部有蜂窝状整 Recently, the feasibility study of measuring and calibrating the technical conditions of the current meter was completed by the Shanghai Institute of Shipping and Transportation Science of the Ministry of Communications, using the bubble-water cartridge introduced by Kampf-Remmers West Germany (1984 product). “Physalis cylinder” cylinder by the different cross-sectional shape of the stainless steel pipe composition, 50 tons of pure water from the bottom of the cylinder water pump driven circulation to the cylinder. There are baffles on the corner of the water tube so as to avoid the vortex when the water turns, the front part of the water tube has a honeycomb shape
