我厂水库调度工作要求每天观测上、下游水位数次,当汛期时工作较紧,再加上雨天、溢洪等给观测工作增加的困难,常使值班人员忙不过来。我们根据工作需要,经过反复试验,因陋就简地制成了这具仪器。共试制了两台,测下游水位的一台使用了十个月,测上游水位的一台使用了三个月,工作可靠。 Our factory reservoir dispatching work requires daily observation of the upper and lower reaches of the water level several times, when the flood season work is tight, coupled with rainy days, overflow and other observations to increase the difficulty of the work, often make the duty staff busy. According to the needs of our work, after repeated tests, we simply made this instrument. A total trial of two, measuring the downstream water level of a used for ten months, measuring the upper reaches of the water level used for three months, reliable work.
