ABSTRACT:
Apparatus and method for measuring oil flowing in a pipe include continuously sampling the cil to provide a stream of sample oil. The temperature of the sample oil is changed by a predetermined amount. The acoustical velocity of the sample oil is determined prior to the temperature change and after the temperature change by sensors providing corresponding signals. A circuit provides a signal corresponding to the water content of the oil in accordance with the acoustical velocity and the known temperature change.
