Monitoring liquid level in a tank or container is a very common application in industry. Water, glue, oil and other liquids need to be stored and pumped to and from various areas of a plant, process and area. Although on the initial look these applications seem quite easy they do require a level of control beyond a simple ultrasonic sensor.
Spectroscopy is the study of how light and matter interacts. Light can be broken up into several regions of the electromagnetic spectrum, so spectroscopy is perfectly suited for accurate real-time analysis and monitoring of continuous and batch processes.
In the oil and gas industry, hydraulic fracturing (fracking) along with horizontal drilling are perhaps the most significant achievements in terms of both engineering and innovation. These achievements enable producers to maximize returns from each well. As a result, the number of hydraulically fractured shale oil and gas wells continue to increase.
