河流、湖泊、水库或地下水流经渠道到取水点时均含有一定程度的泥沙、草根、树叶等杂物。在用管道抽水时,可以用下述两种仪表计量抽取的水量。1 LS农用水表 LS农用水表可作为农业管道灌溉量水之用。该仪器为铁壳,以法兰、螺纹或其它方式串接在供水管道中。当水流流过时冲动仪器中的旋叶,然后通过磁传带动密封室内的计量机构,表上的六位数字计数器随之开始计数。任何一个时段两次读数的差值乘以表上标注的系数(在出厂前经检定所得),即为这一时段内流过的水量。
Rivers, lakes, reservoirs or groundwater flow through the channel to the point when they contain a certain degree of sediment, grass roots, leaves and other debris. When pumping with a pipe, the following two types of meters can be used to meter the amount of water withdrawn. 1 LS Agricultural Water Meter LS Agricultural water meter can be used as an agricultural irrigation water pipe. The instrument is a steel shell, flanged, threaded or otherwise in series with the water supply pipe. When the water flow impulsive instrument when the whirlpool, and then through the magnetic transmission sealed room measuring mechanism, the watch six-digit counter will start counting. The difference between two readings at any one time is multiplied by the factor marked on the form (accredited at the factory) as the amount of water flowing through the period.
