5. Device functions
Throughout these articles, we will use the following terms to describe the main functions of level measurement and control equipment:
the transmitter, which delivers an analog signal generally proportional to the measurement, usually standardized, pneumatic or electronic;
the detector provides information on the presence of a liquid or solid level, and supplies a logic signal;
the indicator provides visual information on the height of a level;
the direct controller integrates all the elements of a control loop.
All these devices may include, either separately or as an integral part, the basic measurement sensor, an essential component, but one which is incapable of delivering information without the aid...
