I have already given an example where we increase the tubing size on a valve to increase the volume of air flow per second. To understand the transfer function look at a sealed capillary transmitter with say 10meter capillary lines. opti morphs toys

Level Measurement 101: Understanding Differential Pressure

WitrynaIn every DP transmitter application, there must be some means of connecting the transmitter’s pressure-sensing ports to the points in a process. Metal or plastic tubes (or pipes) work well for this purpose, and are commonly called impulse lines, or gauge lines, or sensing lines. This is equivalent to the test wires used to connect a voltmeter ...

Diaphragm seals should be properly handled in the field to avoid damage to diaphragm seal and capillary tubing and potential loss of sensing fill fluid. WitrynaOver the length of the impulse line or capillary, cooling should protect the transmitter. This is fine as far as it goes, but real-world users sometimes encounter implementation problems. If the environment is cold, even only intermittently, the impulse line may cool too much, which causes the high-temperature fill fluid to become excessively ...
