tömegáramszenzor

A tömegáramszenzor, often translated as mass flow sensor, is a device that measures the mass flow rate of a fluid. This is distinct from volumetric flow rate, which measures the volume of fluid passing a point per unit time. Mass flow rate accounts for changes in fluid density due to temperature and pressure, providing a more accurate measure of the actual amount of substance being transported.

These sensors operate on various principles. Thermal mass flow sensors are common and work by heating a section of the flow path. The amount of heat lost to the fluid is proportional to its mass flow rate. Other types include Coriolis mass flow meters, which utilize the Coriolis effect to measure mass flow directly, and differential pressure-based sensors that, when combined with density compensation, can infer mass flow.

Tömegáramszenzorok find applications in numerous industries. They are crucial in automotive engine management systems to control fuel injection and ensure optimal combustion. In industrial processes, they are used for precise control of chemical reactions, HVAC systems for accurate air flow measurement, and in the aerospace industry for fuel and air flow monitoring. Their ability to provide a direct and accurate measurement of mass flow makes them indispensable for efficiency and safety in many technical applications.
