Valve Positioner: A valve positioner is a crucial control device that precisely regulates the position of control valves in industrial processes. It receives control signals from a controller and compares them with the actual valve position.

Flowmeter: A flowmeter is an instrument designed to measure the flow rate of liquids, gases, or steam within a pipeline or channel. 

Transmitter: A  transmitter is a device that senses a physical parameter, like pressure, temperature, or level, and converts it into a standardized output signal, usually 4 - 20 mA DC or digital signals.
