Abstract:
     This invention relates to a microwave sensor for detecting to flowing water, especially for detecting the metallic content in flowing water and monitoring the flow of water. This sensor is composed of antenna in the form of vertical whip, horn, or baraboilid, microwave oscillator consisting of transistor, capactor and varactor, echo amplifier including transistor and capacitor and proportional amplifier composed of two operational amplifiers. A high-frequency chock is connected after antenna.
