Method for calibrating a flow sensor with one or two temperature-sensitive resistances

摘要

The method involves varying volume flow continuously from a flow direction to another flow direction by a flow sensor. Total electrical power consumption of electrical resistors (1) or an electrical heater is measured. A measuring signal of the electrical power consumption is reached to a minimum or maximum such that the measuring signal or a simultaneously detected current or voltage signal is stored and is utilized as a signal for operation. The current or voltage signal is changed with resistance change of the resistors or heater.
