2. How Guided Wave Radar Level Measurement Works
Although radar has been employed for industrial level measurement for many years, the concept is still perceived by some as a new technology. In certain cases, this perception has limited radar’s uptake in applications where it may provide a clear advantage over existing technology. Here we consider how guided wave radar level measurement works, specification considerations, and where and when it provides a clear application advantage.

4. Can Ultrasonic Level Sensors Do Leak Detection?
Ultrasonic level sensors are incredibly versatile instruments. They can be very accurate, even from a long distance. They can be used with a wide range of chemicals since they don’t need to be in contact with the substance being measured. They can be used to measure liquids or solids, and software allows them to be configured easily. There is one thing, however, that ultrasonic level sensor can’t do … No matter how they are configured, they can’t be used as leak or liquid presence detectors.

5. A Solution for Separation Success
In hydraulic fracturing (fracking) operations at oil and gas wells, water and oil both come to the surface and must be separated. The process of removing water from the separation vessel is referred to as a "Water Dump." The water is "dumped" to a treatment plant for processing, while the oil is removed from the top for further refining. Because of the high cost of treating the water, it is critical to know when the interface between the water and oil reaches a low point to prevent dumping oil to the water treatment facility. For water dump control, an on/off capacitance level switch inserted near the water outlet is almost always the preferred solution.
