(一)原理根据某一物体(一般指固体)在水中受有一定大小的浮力,并当该物体本身的重量小于它在水中所受的浮力时该物体不会下沉,浮于水面,并随着水位的升降而升降。本浮标水位计之设计除根据上述原理外也参照了苏联西蒙诺夫所设计的卷带水位计的主要部分结构和原理。 (A) Principle According to an object (usually refers to the solid) in the water by a certain size of buoyancy, and when the weight of the object itself is less than its buoyancy in the water when the object will not sink, floating on the water and As the water level rise and fall. In addition to the above principles, the design of the buoy water level gauge also refers to the structure and principle of the main part of the water level gauge designed by the Soviet Union Simonov.
