在砼配合比的设计和施工中,“水灰比”是决定砼质量的一个重要因素;理想的“水灰比”又取决于水和灰的准确计量。水的计量往往不引起人们的重视,许多建筑工地不严格控制水量,或因水计量机构失灵而干脆采用人工随意加水的现象,几乎普遍存在。JSK-S型晶体管水位控制器有以下优点:(1)灵敏度高,可靠性强,计量准确;(2)按“水灰比”的要求,一次计量后可分多次放
In the design and construction of concrete mix ratio, “water-cement ratio” is an important factor in determining the quality of cockroaches; the ideal water-cement ratio depends on the accurate measurement of water and ash. The measurement of water often does not cause people’s attention. Many construction sites do not strictly control the amount of water, or simply use artificial random water to add water due to the failure of water metering institutions, which is almost universal. JSK-S transistor water level controller has the following advantages: (1) high sensitivity, high reliability, accurate measurement; (2) according to the “water-cement ratio” requirements, can be divided into multiple times after a measurement
