niveaukontrollers

Niveaukontrollers, also known as level controllers, are devices used to monitor and regulate the level of a substance, typically a liquid or gas, within a tank, vessel, or pipeline. Their primary function is to maintain the substance at a predetermined setpoint, preventing overflow, emptying, or maintaining a specific operating range.

There are various types of niveaukontrollers, each employing different sensing principles. Float-type controllers are common and rely on a buoyant element that rises or falls with the liquid level. As the float moves, it actuates a switch or valve. Other types include conductivity probes, which detect the electrical conductivity of the substance, capacitance sensors that measure changes in capacitance as the level varies, and ultrasonic sensors that use sound waves to determine the distance to the surface. Pressure sensors can also be used, as the hydrostatic pressure of a liquid is directly related to its height.

Niveaukontrollers find widespread application across numerous industries, including water treatment, chemical processing, food and beverage manufacturing, and petrochemicals. They are crucial for ensuring process safety, efficiency, and product quality by preventing hazardous conditions, optimizing resource usage, and maintaining consistent operational parameters. The output of a niveaukontroller can be used to directly control pumps, valves, or alarms, automating the level management process.
