With over 20 different level measurement technologies on the market today, it is important to choose the right level transmitter for your process conditions. This document provides information on two of the most commonly used level measurement technologies – Ultrasonic and Guided Wave Radar (GWR). Ultrasonic technology has been on the market for years and is still considered a trusted technology throughout the industry. Ultrasonic is non-contacting and offers a cost-effective solution for most straight-walled tank applications. Over the years, however, newer level measurement devices have emerged into the market and are quickly capturing market share from older technologies that use sound or echo-based measurement – including Ultrasonic transmitters. Technologies such as Guided Wave Radar (GWR) are price comparable and have proven to be a much more reliable solution in even the most irritating conditions. Guided Wave Radar is suitable for both liquid and solid applications and operates independent of process conditions. In today’s market, Guided Wave Radar is among the most versatile technologies being used for level measurement. Additionally, unlike Ultrasonics which tend to be installation sensitive, Guided Wave Radar offers a solution that will work in all applications.
