This company has enhanced its Rosemount 5300 Guided Wave Radar Level Transmitter (photo) to optimize separation process performance and prevent costly product ingress by accurately measuring a thinner top liquid layer in interface applications. The Rosemount 5300 can now also perform measurements to the top of a tank, enabling increased throughput and profitability. In interface-measurement applications, such as separators, the top product layer must be of a certain minimum thickness for a guided-wave radar transmitter to distinguish between the echoes from the two liquids. Previously, this minimum detectable thickness would be between 50 and 200 mm. The company’s patented “Peak in Peak” interface algorithm now enables the Rosemount 5300 to detect a top liquid layer of just 25 mm. — Emerson, St. Louis, Mo.
