Abstract: A system is provided for monitoring foam levels within a vessel wherein one or more chemical reactions or biological growths are occurring. The system includes a resonant sensor positioned outside of the vessel at a position to measure foam level within the vessel, the resonant sensor having an inductive element and a capacitive element and tuned to provide for enhanced sensitivity of changes in local permittivity to resonate.

Abstract: A system for reading at least one wireless resonant sensor includes a signal parameter measuring device, a reader housing, a computing device electrically connected to the signal parameter measuring device, and a plurality of reader antennas disposed within the reader housing and electrically connected to the signal parameter measuring device, wherein the plurality of reader antennas comprises a first reader antenna for signal output and a second reader antenna for signal input. The signal parameter measuring device is configured to sweep frequencies over a range of frequencies to acquire signal parameters for the wireless resonant sensor.
