In continuous level measurement, the level of a medium in a tank or silo is detected with the help of different measuring methods and converted into an electronic signal. Typical applications for continuous level measurement are process tanks, storage tanks or silos in the process industry. Continuous level measurement systems can be used in liquids, pastes, powders and bulk solids.
The proportion of solid matter in a liquid is determined with the help of density measurement. Typical applications in the process industry are the measurement of acid and lye concentrations, the mixture density of abrasive or sticky liquids and the sold matter content of sludges and slurries.
In point level detection, a point level switch detects when a certain, predefined level is reached. Such a device is employed when it is not necessary to measure every possible intermediate level. A switching command starts or stops filling equipment such as levels or pumps. Point level detection systems can be used liquids, pastes, powders or bulk solids.
Pressure measuring techniques can be used to measure not only process pressure or differential pressure, but also level, volume, density or mass flow in all areas of process technology. The measuring ranges of pressure transmitters starts at a few mbar and extend to extreme pressures up to 1,000 bar. Pressure transmitters deliver high precision readings in gases, vapors and liquids.
