: I am a Marine Engineer whose esxperience on steam plant is limited to 1950's technology. I am studying towards my Stage 5 Certification in Power and Plant engineering and need information on modern electronic boiler water level control. Any infomation on operaion of automated controls would be appreciated. Thanks.

If you are using a distributed control system, you will have a transmitter in the field. It measures the desired variable (pressure, temperature, flow, level, etc.) and sends an electronic 4-20 milliamp or 1-5 volts dc, or similar signal to a central data control centre. There, a system of computerized equipment receives, compiles and deals with all the information in order to produce automatic control for the equipment. The operator can then control and/or monitor the process from a computer screen.

Is this what you meant? E-mail me for further info.
