Pressure transmitter spacing
Thread Content
What is the installation spacing between 3 pressure transmitters taken 2 at a time on the same pipeline?
It’s the distance between the pressure measurement points, right? The specifications do not set specific requirements; for the sake of easy installation and maintenance, a distance of around 15 CM is generally suitable. If the valves are placed too close together, those in the same row will interfere with each other.
The closer the three measurement points for the two-out-of-three pipeline pressure determination are to each other, the more accurate the pressure value obtained will be. However, other factors must also be taken into account during actual installation: 1. It is necessary to ensure that the heat-affected zones resulting from the welding of the two pressure tapping pipes on the process pipeline do not overlap. 2. It is necessary to ensure that the fittings and valves on the two pressure tapping pipelines do not affect each other. Generally, a spacing of 100~150 mm is more common.
No special consideration is needed; for transmitters from the same pipeline, if it is not possible or convenient to separate the sampling points, it is meaningless to arrange the instruments separately in order to ensure \"safety\".
No special consideration is needed; for transmitters from the same pipeline, if it is not possible or convenient to separate the sampling points, it is meaningless to arrange the instruments separately in order to ensure \"safety\". One end cannot be separated, and the other end takes into account single-point failures; it does not constitute a complete redundant structure.
