Regarding the flange connection of the transmitter
Thread Content
The flange connection of the transmitter must be aligned with the pipeline. In the 3-to-2 installation configuration, as long as it is possible to work on the flange, additional holes must be drilled in it to meet the requirements for fluid testing. 1) Tapings on the transmitters should be taken from the same side of the pipe, and this applies to 2-out-of-3 (2oo3) configurations. 2) Additional tapings must be drilled in the flange to suit the fluid being measured, provided that the flange can be modified. I’m not quite sure about point 1); please help me understand it! As for sentence 2), it should read: “For the 3-out-of-2 installation scenario, as long as the flange can be processed, additional drilling must be done in the flange to meet the requirements of fluid testing.” ”But why do this? Please give some advice, experts! Thank you!

Please leave comments on my translation!
1) Tap connections for the transmitters should be made on the same side of the pipe, especially in 2-out-of-3 (2oo3) installations. 2) Additional taps must be drilled in the flange to suit the fluid being measured, provided that the flange can be modified. 1) For 3-out-of-2 instrument installations, all tap connections for the transmitters must be located on the same side of the pipe. 2) The flanges provided should be drillable to meet the requirements for additional pressure tapping, in order to satisfy fluid measurement needs. A hole should be drilled in the neck of the flange to take pressure readings.
1) The pressure taps for the transmitters should be taken from the same side of the pipe. Pressure readings should be taken on the same side of the pipeline. 2) In 2-out-of-3 (2OO3) configurations, additional pressure taps must be drilled in the flange in order to suit the fluid being measured, provided that the flange can be modified. For 3-out-of-2 configurations, additional taps need to be created by drilling holes in the flange to accommodate the fluid being measured, and the flange must be adjustable.
For any sampling points of important instrument data, there are 3-out-of-2 or even 4-out-of-3 configuration options available. The purpose is simple: to ensure safety and reliability when taking samples. For example, if only one opening is left and it is blocked, the gauge will no longer function.
Reply to 2# Saiwai Jiangnan: The tapping is not a flange, but rather a reserved sampling port used to connect to the transmitter. In 2-out-of-3 (2oo3) installations, some important parameters are measured using three identical transmitters; a confirmation is given only if at least two of them meet the specified conditions. 1. The sampling port should be located on the same side of the pipeline ； 2. For 3-to-2 instruments, if the flanges for the sampling ports can be machined further, sampling ports should be installed on those flanges separately. Some flanges cannot be further processed, such as lined flanges.
Is the brother on the 6th floor from the Jianghan Oilfield? I also worked at the Jianghan Oil Field.
