Abstract

A sensor arrangement and method for measuring the speed of sound in a gas to determine gas characteristics, such as composition, temperature and/or humidity of the gas. The sensor arrangement includes a sound sender, first and second sound receivers, and a signal processing unit. The sound sender and sound receivers are arranged such that the travel distance of the sound provided by the sender to the first receiver is different from the travel distance of the sound provided by the sender to the second receiver. Further the arrangement includes the signal processing unit connected with the sender and the receivers which operates to determine the gas characteristics.
