浮子式水位计已有百年的历史,无论是国内还是国外,其使用量至今仍占多数地位。浮子是感应和传动水位变化的部件,它既偿是精密机械,又没有电子电路,往往不被重视,但它对水位计的驱动力矩、精度、可靠性起着主导作用。然而,由于现行国内外标准中存在一些问题,以致大多数水位计无法达到国际标准所规定的指标,为此笔者提出一些 Float-type water level gauge has a history of one hundred years, whether domestic or foreign, its use still occupy the majority position. Float is the sensing and transmission parts of the water level changes, it is a fine precision machinery, and no electronic circuits, often not be taken seriously, but it plays a leading role in the driving torque, accuracy and reliability of the water level gauge. However, due to some problems existing in the current domestic and international standards, most of the water level gauges can not meet the targets set by international standards. Therefore, the author proposes some
