Abstract
A measurement method for measuring the temperature of water in a meter includes the steps of: causing an emitter transducer of the meter to emit an ultrasonic measurement signal, and acquiring an electrical measurement signal produced by a receiver transducer of the meter; measuring a speed of the ultrasonic measurement signal in the water and a level of the electrical measurement signal; using the level of the electrical measurement signal to determine whether the temperature of the water is less than or greater than an inflection temperature corresponding to a point of inflection; estimating the temperature of the water from the speed of the ultrasonic measurement signal by using a first formula if the temperature of the water is less than the inflection temperature, and by using a second formula if the temperature of the water is greater than the inflection temperature.
