爱德华真空计是利用恒定流量法或瞬态法测量气体流量的真空计。其中，恒定流量法是利用温度控制器控制电热丝的温度，使电热丝表面达到一定温度时，在一定的压力下，气体的流量是一个固定值。当气体的压力或流量发生变化时，电路会自动调节电热丝温度，使气体的流量恢复到原来的固定值。瞬态法则是利用真空室内气体被抽出后，加入小量气体，通过观察真空室内气体的压力变化来测量气体流量。
爱德华真空计类别：
1. 热电离真空计：适用于测量10^-4 ~ 10^-11 Pa范围的气体压力。
2. 恒定流量真空计：适用于测量10^-4 ~ 10^-2 Pa范围的气体压力。
3. 热阴极离子化真空计：适用于测量10^-3 ~ 10^-10 Pa范围的气体压力。
4. 悬挂式真空计：适用于测量10^-2 ~ 10^-6 Pa范围的气体压力。
