Written test be usual
questions will be pressure
conversions, temperature
sensors, massflow nevering
technique, control valve over
hauling etc. In interview They
ask questions about P&I
diagrams and their symbol
expansions. You should know
to develop a diagram. More
often they question about
differential pressure
measurements in orifice
plates. And about
thermocouples! Pipeline
standards! DCS architecture
