Abstract (en)
[origin: WO2020088914A1] The invention relates to a method for determining a velocity of a fluid stream in the region of a particle sensor, in which the fluid stream moves along a flow path, the particle sensor has a particle charging device arranged at a first position of the flow path arranged for charging particles in the fluid stream and a measuring device arranged at a second position of the flow path located downstream relative to the first position for determining at least one electrical variable of the fluid stream, the method comprising the following steps: determining a first period of time which characterises an electrical variable of the particle charging device, determining by means of the measuring device a second period of time which characterises at least one electrical variable of the fluid stream, evaluating the second period of time in relation to den first period of time.
