Can pressure transmitters be installed without pressure conduits?
Thread Content
When installing a remote transmitter gauge, is it possible to avoid installing pressure transfer pipes and install it directly in the same way as an on-site gauge?
Yes, as long as the pipeline vibration is not severe and the temperature is not high, a short coupling can be used to directly connect the transmitter
Short installation refers to this approach, but it is affected by factors such as the medium and the environment – for example, whether maintenance is easy, whether vibrations affect normal operation, and whether the temperature of the medium is appropriate, among others. .
The environment can be taken care of, maintenance can be done – there’s no problem at all
Some factories even require the installation to be completed as quickly as possible.
Yes, but vibration, temperature, medium slag discharge, and other factors need to be considered comprehensively.
If permitted, try to keep the installation as short as possible; in the north, a shorter installation facilitates heat tracing and makes maintenance easier. :)
Good fortune hides within misfortune, and misfortune is intertwined with good fortune. When pipeline pumps and valves have emergency stop and start functions, the use of short pipes for pressure measurement can lead to pressure surges, which may damage the sensor diaphragm or cause fatigue in the sensor, thereby significantly reducing its service life. Therefore, depending on whether to use a long or short version, fluid dynamics analysis and heat conduction analysis must be conducted, and a calculation method is needed.
Yes, it’s possible, as long as your medium is ordinary and not exposed to high temperatures
Temperature transmitters never require the installation of pressure tubes, and some level transmitters used for displacement measurement also do not need pressure tubes.
I still don’t like using those complicated ways
