Pressure Transmitter: Installation(3)
From last news, we know how to install Pressure Transmitter and how to install Inlet Pressure Pipe, but do you know notes for installation of pressure tube and smart pressure transmitter? Let’s study it.
Notes for installation of pressure tube and smart pressure transmitter:
1) The inlet pressure pipe should be as short as possible in the case of meeting the needs.
2) Corrosive or overheated medium should not be contacted with the transmitter directly.
3) The inlet pressure pipe should be installed in the place where the temperature gradient is low and fluctuation is small.
4) Working temperature limit must be paid attention to when high temperature medium is to measure.
5) For differential pressure transmitter, the two inlet pressure pipes should be kept at the same temperature, and the hydraulic height should be kept balance (For differential type).
6) The inlet pressure pipe should use large-diameter pipe as far as possible in case of the friction effect.
7) For differential pressure transmitter, the liquid-level of the two inlet pressure pipes should be kept at the same height when isolating gas is used.
8) When injection system is used, the system should be as close as possible to the pressure port of flow pipe. And the purifying liquid should get through from the pipes of the same size, length of pipes to the transmitter. Also the injection liquid through transmitter should be avoided (For differential type).
