Real-time water concentration measurement in bitumen is critically important during all operating processes from extraction to refining. Having a low-cost, noncontact sensor that can operate in high temperatures is vital in terms of energy conservation, process optimization and elapsed time. This paper presents a specific design of a microwave coupled split ring resonator-based sensor, with a ground-gap-coupled transmission line as the reader. The tag is a metallic trace with the theoretical capability to sense in ultra-high temperatures far beyond the maximum temperature used in bitumen refineries and is electromagnetically coupled the reader, enhancing the coupling distance up to 60 mm. Therefore, the proposed sensor is well adapted to measure in harsh environmental conditions. Various simulations are conducted and compared against experimental results, verifying the features for the introduced sensor such as the capability to measure at temperatures higher than 200 degrees C, extremely high sensitivity of 500 kHz (1% of water concentration variation) and measurement in both steady-state and turbulent conditions.
