Abstract

In a method and an arrangement for acoustic determination of an instantaneous fluid temperature, acoustic velocity V in a fluid is monitored and an output signal related to the acoustic velocity is generated. A conventional temperature sensor senses a fluid temperature TS and generates an output signal related thereto. A signal processor receives the signals from the sensor and the acoustic velocity monitor determines the instantaneous fluid temperature TA based on a relationship:TA=kV2;where k is a constant dependent on the composition of the fluid that is calculated within the signal processor based on the relationship:k=TS/V2
