What type of system consists of measuring instruments and controllers that work together to control a process?

The type of system that consists of measuring instruments and controllers working together to manage a process is best identified as a control system. Such systems are essential in industrial settings where maintaining specific conditions such as temperature, pressure, flow, or level is necessary for efficient operation.

Control systems use sensors to gather data about the process, which is then analyzed by controllers. Based on this information, the controllers make adjustments to various elements of the system to ensure that the process operates within designated parameters. This interaction creates a continuous loop of measurement and response that is vital for optimizing performance and ensuring safety in operations.

While monitoring systems are primarily concerned with observing and reporting on the state of a process, and feedback systems specifically refer to those that provide data back to the controller for modifications, the term "control" broadly encapsulates the entire process of regulating a system through active management of its variables. Automatic systems imply an absence of human intervention, but they still rely on the underlying control mechanisms to function effectively. Therefore, the comprehensive nature of a control system aligns with the definition presented in the question.
