UWT Level Control’s Measuring principles for level detection / level measurement
The measurement methods that UWT distinguish between are, Level Detection and Continuous Level Measurement.
Level detection is used to measure a predefined fill level, and continuous level measurement is the continuous checking of the level of the medium in a silo or a hopper.
The different measuring principles which are used in the field of level measurement technology are explained here in detail.
UWT’s Level Detection Measurement Method
Level detection is used to avoid overfilling or downtime in silos and containers. Level limit switches are also used as spillage detectors in pipes or for the measurement of levels in interface applications. The switching point depends on the installation position of the sensor and its configuration. The information is analysed and transmitted via a digital signal to the control unit directly or via a fieldbus. Other operations and alarms such as a filling stop and start, or demand signal can thus be triggered. Level switches are used in solids, liquids or sticky media.
UWT’s Measurement method – continuous level measurement
Continuous level measurement, the constant determining of the fill level, is already built into many silos, containers or process vessels, in order to implement optimum material logistics. For these measuring applications various factors such as silo and vessel geometry, sensor mounting position, the properties of the medium such as flowability, bulk density, conductivity, moisture, dust and adhesion all play a role and must be considered when selecting the right measuring principle.
