甘肃省景泰川灌区,属高扬程、大流量电力提灌,灌溉成本高,形成了水的商品化,在计量上更需要精确。灌区灌溉试验站1975年研制成堰槽自记水量计,安装在支斗渠上,经10年的运用效果良好。其特点是:结构简单,造价低廉(40元/台),图表直观,操作容易,适应性广。并可连续记录时段内的水量,是灌区堰槽自记量水的理想工具,现简介如下。
Jingtai River Gansu Province irrigation area, is a high-lift, high-flow power irrigation, irrigation high cost, the formation of the commercialization of water, the need for more accurate measurement. Irrigation experimental station Irrigation area developed in 1975 into a tank weir water meters, installed in the branch channel, after 10 years of good results. Its features are: simple structure, low cost (40 yuan / Taiwan), visual chart, easy to operate, wide adaptability. And can continuously record the amount of water during the period is the irrigation tank weir slot water from the ideal tool, is as follows.
