A level measurement transmitter or sensor is an instrument used to determine the level of liquid or bulk solid at a particular time. The level transmitter provides an electrical output proportional to the level of a liquid, or bulk solid in a confined space. There are two main classifications of level transmitters: Point level transmitter and Continuous level transmitter. Point level transmitters are designed to indicate whether the liquid has reached a specific point, while continuous levels are used to render precise liquid level measurements.
