无水银差压流量计是相对有水银差压流量计说的。有水银差压流量计是仿苏的浮子式差压计。它的工作介质是水银,水银是一种容易蒸发的有毒金属,对人体健康有一定影响。而且水银又是一种贵重的稀有金属,是国防工业的重要原料。以前,全国有大量水银差压计在冶金、化工、石油、发电、纺织等重要部门使用。经过无产阶级文化大革命锻炼的工业战线上的广大 Mercury-free differential pressure flow meter is relatively mercury differential pressure flow meter said. A mercury differential pressure flow meter is imitation Su float-type differential pressure gauge. Its working medium is mercury, mercury is a volatile metal easily evaporate, have a certain impact on human health. And mercury is a precious rare metal, is an important national defense industry raw materials. Previously, a large number of mercury differential pressure gauges were used in major sectors such as metallurgy, chemicals, petroleum, power generation and textiles. After the great proletarian cultural revolution tempered the industrial front of the vast
