Flow sensor for monitoring a flow parameter and method of determining the same

摘要

A flow sensor for determining a flow parameter of a fluid is shown in embodiment examples of the present invention, comprising a sensor chip, which has at least one thermal membrane sensor element, which is designed to determine the flow parameter of the fluid in a measurement region or to determine a fluid temperature of the fluid, wherein the thermal membrane sensor element has two thermocouple junctions arranged at a distance from each other and a heating element arranged between the thermocouple junctions, and wherein the sensor chip is designed for the fluid to flow around the sensor chip as a freestanding sensor finger during the operation of the flow sensor.
