Regarding the parameters in the instrument design specification sheet
Thread Content
In the specification sheet for instrument design, which parameters need to be provided by the manufacturing process? What are the general criteria for choosing the material of instruments?
Medium properties, such as temperature, pressure, flow rate, viscosity, density, molecular weight； Equipment characteristics, such as pipe material, diameter, and pressure rating ； Connection parameters, such as the connection diameter, distance, and method between the instrument and the device. That’s as much as I can remember for now.
Thank you very much. Device specifications should be provided by the device manufacturers themselves; a poor-quality manufacturing process cannot even provide the necessary process parameters.
