Optimizing Fluid Sensors for Industrial Process Measurement

When processing pharmaceutical products, how do you tell if a fluid is of high quality? If you are working with crude oil, how do you know how much you are extracting? If you are transporting water, how do you know the flow rate? Such questions, which impact confidence and bottom lines for water, food, life sciences, and oil and gas companies, are addressed by the manufacturers of flowmeters that are installed in pipelines and other equipment.
