An arrangement for measuring the moisture content of an aqueous substance by using microwaves produced by a transmitting arrangement formed by a signal source and a transmit aerial connected thereto. A portion of the aqueous substance is disposed in the field of radiation of the transmit aerial, and a receive aerial for receiving the transmitted wave is immersed in the substance. An evaluation arrangement is connected to the receive aerial for measuring a phase change of the wave in the substance. The phase change represents the moisture content of the substance.
