1. Equipment verification: Due to the fact that the provided equipment is not the same as the design supplier and model, it is necessary to determine the transmitter corresponding to each tag number based on the range, design installation method, and material requirements of the process medium.
2. Determine the installation location of Siemens transmitters: Various series of pressure transmitters should adopt waterproof and dustproof structures, which can be installed in any place. However, considering the convenience of daily operation and maintenance, extension of service life, and assurance of reliability, the installation location has the following requirements:
1) There is sufficient workspace around, with a distance (in any direction) greater than 0.5m from adjacent objects;
2) There is no severe corrosive gas around;
3) Not exposed to surrounding thermal radiation and direct sunlight;
4) To prevent interference with the output caused by vibration of the transmitter and pressure tube (capillary), the transmitter should be installed in a vibration free location.
