| 摘要 |
The invention relates to a device for measuring the flow rate of a fluid, comprising a fluid-conducting housing (1), at least one electronic sensor (2), producing an output signal (Q) which varies in proportion to the actual flow rate, a temperature sensor (2.1), producing a temperature signal (T) and an analytical unit (3) where the processing of the sensor signals (Q, T) occurs. Temperature-dependent material values for one or several fluids are stored in at least one data store (4, 4.1 - 4.4). The temperature-dependent material values are related to the applied sensor (2) and an arithmetic unit (5, 5.1) determines the flow rate as a function of the material values for a fluid to be measured and an instantaneous sensor signal (Q). The arithmetic unit (5, 5.1) is thus connected to the data store (4, 4.1 - 4.4) and the sensor (2, 2.1). |
