strømningskontakt

Strømningskontakt is a Norwegian term that translates to "flow contact" or "stream contact" in English. It refers to a type of sensor or switch designed to detect the presence or absence of fluid flow within a pipe or conduit. These devices are crucial in various industrial and domestic applications where monitoring and controlling fluid movement is essential.

The primary function of a strømningskontakt is to provide a signal, typically electrical, when a predefined flow rate is reached or when flow stops altogether. This signal can then be used to trigger other actions, such as activating a pump, shutting down a system, sounding an alarm, or initiating a process. The mechanism behind their operation can vary, but common types include paddle, turbine, or thermal dispersion sensors. Paddle types use a small vane that is moved by the fluid, while turbine types have a rotor that spins with the flow. Thermal dispersion sensors measure temperature changes caused by the moving fluid.

Strømningskontakter are employed in a wide range of systems, including heating, ventilation, and air conditioning (HVAC), water treatment, chemical processing, and cooling systems. They are vital for ensuring efficient operation, preventing damage from dry running pumps, and maintaining safety by detecting abnormal flow conditions. Their reliability and simplicity make them a common choice for flow monitoring applications.
