Water Fraction Measurement Using a RF Resonant Cavity Sensor

Heron Eduardo Ávila, Daniel Juan Pagano, Fernando Ragel Sousa
  • Abstract:
    We have tested the working principle of water fraction measurement using a Radio Frequency (RF) resonant cavity sensor. This technology allows us to determine the water fraction by the frequency shift of the first resonant peak in a non-intrusive way. The sensor operates with low power signals (1 mW) in the range of 100 through 400 MHz. Static measurements were done using a Scalar Network Analyzer (SNA) for water/oil and water/air static mixtures with fresh water and sea water. The measurement’s uncertainty and the characteristic curves of the sensor’s behavior were computed.
