Flowtech Type Level Transmitter or level transducers are used to measure the level of a liquid or bulk solid material (as well as slurries) within a specified space, and to provide electrical output about these measurements that are proportional to the input level. Level transmitters are designed to measure level based on either a point level or continuous level readings. Point level transmitters provide output when a specific level measurement is reached. This output is generally in the form of an audible alarm or an electrical charge to actuate a switch. Multiple point level transmitters can be integrated together to give a stepped version of continuous level. Continuous level transmitters,measures level within a specified range and provide output as a continuous reading of the level. Level transmitters can operate through a wide range of temperatures, pressure, vapour gas mixtures,and process conditions. Measuring range.
