摘 要:到目前为止,还没有适合低压管灌系统特点的量水仪表,于是建立了管道中心流速和断面平均流速的关系,采用传感器的方法,研制出了SGS型水量计,这种水量计专门为低压管灌系统而设计,具有价格低廉,精度较高,不需交流电源,使用方便等显著特点。There has not been any water meter suitable for low pressure pipe irrigation system up to now. In view of this we have developed the relation between center velocily of pipe and cross section mean velocity and with the help of sensing unit method developed the water meter of Type CGS. This kind of water meter was designed for low pressure pipe irrigation system specially. It is characterized by it's low price, high preciseness, needlessness of a. c. power sourse and being easy to use.
