i have two manometers with different diameter. can i use both in same scale or separate scales are required? because for same pressure difference height of columns would be different for different diameters?
When you have a manometer with mayor diameter is possible to put more traces in the scale, then you can appreciatte with more precision. This ocurr because a width of each trace have 0.3mm or 0.4mm. More diameter, more space, better precision.
