摘要

With today's increased emphasis on product quality and environmental concerns, the operators of industrial processes need better tools to monitor their process and waste streams. Once these fluid streams are designed and in place, however, it is often difficult and costly to install new monitoring devices, especially if installation would require the shutdown of a critical part of the production process. In addition, operators may not know the best location to monitor the composition of the fluids - it may be required in the process at several points. There is an industry need for a sensitive monitor of fluid streams that can be easily and economically installed and maintained without process interruption. A new ultrasonic technology has been developed which monitors the composition of fluid mixtures from the outside of the pipe or vessel. On-line information is provided about the fluid composition for both product quality assurance and process improvement. Due to the non-intrusive design, installation is easy and does not require cutting the pipe. Two sensor assemblies are simply clamped to opposite sides of the process pipe, and sensor cables are run to the electronics unit. Once the sensors are calibrated for one location, they can be moved and the measurement technique can be applied at many locations. The ultrasonic contamination monitor has been tested and proven for several applications within the petroleum and chemical industries. This paper describes the measurement technique and the experimental system developed to test the technique in the field. Two different field experiments are described, both intended for application in the petrochemical industries.
