Parametric monitors can vary in type and purpose. We can differentiate "general purpose" monitors utilized in various spheres and applications. These monitors can include measuring tools, an informational display for users, and a transmitter that sends data readings to a control system. Such systems may be utilized in offices as well as private homes.

There's also a group of monitors utilized at production lines, especially the ones connected with fluid or gas transportation. Such devices are called "in-line monitors", and they are inserted directly into the pipe system to provide continuous measurements taken directly from the system. Most commonly such reading concern flow parameters or quality attributes of the substance.
