Differential pressure level gauge
Thread Content
Why are some equipped with two capillaries while others have only one, with the gauge directly connected to the diaphragm?
The two capillaries are differential pressure transmitters that measure the differential pressure； One is a pressure transmitter, which measures pressure.
It’s a sealed container with two capillaries. The pipe is sealed with nitrogen, etc.; the upper and lower flanges are under equal pressure. The difference in pressure exerted by the medium on the lower flange compared to that on the upper flange determines the liquid level! The single-flange type is an open-container design used for measuring differential pressure; the upper flange has been removed, which means it measures pressure relative to vacuum at low pressures
The question is too unclear, so there’s no fixed answer! A differential pressure gauge has two capillaries ； There is also one side with capillaries and the other side with pressure guide tubes ； Of course, on one side there is the flanged diaphragm transmitter, which is mounted directly on the equipment, while on the other side there can be a capillary tube or a pressure transfer tube – either works! It mainly depends on the properties of the gas phase and liquid phase (or other different medium conditions).
Since their functions are different, the choice also varies; it depends mainly on the design requirements whether to use a single-flange diaphragm seal or a double-flange diaphragm seal
In the arts of China, there are one-armed immortals, two-legged cripple masters, and even those who can use their farts as projectiles – get it? :lol
Shandong is a province that claims to be able to summon spirits and control the weather – it’s really amazing, huh.............. :lol
Is it because it eliminates the need for a capillary and also avoids the requirement for a support frame? It depends on actual needs; think about it by yourself
