一、电容式关压计的特点差压计是一种常用仪表,主要用来与节流装置配套进行液体、气体及蒸汽的流量测量,也可测量液体或气体的差压、压力、负压以及液体的液位。用差压原理进行流量测量仍是流量测量的主要方式,约占流量计总数的60~7O%。差压计的品种很多。受苏修的影响,我国生产了很多水银浮子式差压
First, the characteristics of capacitive barometer Differential pressure gauge is a commonly used instrument, mainly used with the throttling device supporting liquid, gas and steam flow measurement, but also the measurement of liquid or gas pressure, pressure, negative pressure As well as the liquid level. The principle of differential pressure flow measurement is still the main method of flow measurement, accounting for about 60 ~ 7O% of the total flowmeter. Variety of differential pressure gauge. By the Soviet revisionist effect, China produced a lot of mercury float-type differential pressure
