Ultrasonic level switches use high-frequency sound waves that are easily transmitted across a transducer gap in the presence of a liquid media, but are attenuated when the gap is dry. The Magnetrol® ultrasonic portal, echotel.magnetrol.com, provides information about the Echotel® series of ultrasonic switches and how they can improve the safety and efficiency of many processes. Periodically, MAGNETROL product manager Tom Kemme answers questions about ultrasonic level switches in the portal’s “Ask Tom” column. This week’s blog post shares some recent Q&As.

In order to optimize performance of instruments, operators need reliable software that can be used to configure a device for the specific application. In the past, it has often been necessary to use several different manufacturer-specific programs to operate different field instruments to their fullest capacity.

Guided wave radar technology (GWR) has emerged as a level measurement staple in many industries around the world. Since its introduction in the late 1990s, users of GWR have discovered that it has unique characteristics that make it well suited for difficult level control challenges

Radar technology has revolutionized level measurement in a variety of process industries since the introduction of 4-20mA loop powered, radar-based transmitters in the 1990s. Both guided wave radar (GWR) and non-contact radar have numerous advantages over older, more established level measurement technologies. 

Plant operators in the water and wastewater treatment industry are searching for ways to strategically manage energy usage and increase efficiency.

Utilizing and maintaining level and flow control instrumentation requires knowledge of a wide range of technical information.
