Self-Heating Thermal Dispersion Sensor System

Abstract

A sensor system including a sensor probe configured to house one or more coils of resistive electrical wire, an electrical circuit configured to energize each coil so as generate heat within the sensor probe and receive output signals from each coil, the sensor probe comprising a heat transfer material designed to facilitate heat transfer between the sensor probe and a surrounding medium surrounding the sensor probe, and a processing unit configured to measure the output signals from each coil to determine changes in level, temperature, and/or flow rate of the surrounding medium based on changes in the output signals.
