CONTROL MONITORING INSTRUMENTATION FOR OIL GAS

Industrial instrumentation is used to control and monitor conditions including temperature, pressure, and fluid levels in processing facilities, oil refineries, petrochemical plants, oil and gas pipelines, and distribution operations. Common applications of oil and gas instrumentation include monitoring the presence of flammable and combustible gases in production and storage areas and monitoring emissions for pollution control. Instrumentation is also used for monitoring and controlling flow in delivery systems.

There are two types of instrumentation used in equipment monitoring: input & output. Input instruments are used to monitor or measure temperature, flow, pressure, and levels in equipment including transport pipes and vessels. Output instruments, on the other hand, include controls & alarms that display readings or provide an alert to warn of potentially hazardous situations.

The three primary components of industrial instrumentation are sensors, transducers, and transmitters.

Sensors:   measure the physical properties of a solid, fluid, or gas. In the oil and gas industry, sensors provide continuous measurement to detect and monitor gas and gas emissions.

Transducers:  convert variations in temperature, pressure, flow, or level into an electric signal that is then picked up by a transmitter.

Transmitters:  serve as an interface between sensors and measurement instrumentation such as level sensors, flow meters, and pressure sensors. This equipment is responsible for sending a digital signal to the main control system.
