The new Sitrans FS230 clamp-on ultrasonic flow system (photo) is a combination of the Sitrans FST030 transmitter and Sitrans FSS200 clamp-on sensors. The Sitrans FST030 transmitter includes a digital sensor link that digitizes the signal at the earliest stage of measurement, resulting in an optimal signal-to-noise ratio. Due to its 100-Hz data update rate and integrated PerformancePlus algorithm, the transmitter detects even the smallest changes in flow for consistently high accuracy of 0.5 to 1% of flowrate and a very stable zero point, says the company. Its patented pipe configuration menu allows the user to select various upstream pipe anomalies and automatically adjusts for flow-profile disorders stemming from unfavorable upstream conditions. The Sitrans FST030 also offers comprehensive diagnostics that detect changes in aeration, signal quality, sonic speed, temperature and fluid type, providing a valuable window into the process and facilitating preventative maintenance. Common architecture between digital platforms reduces training and spare part requirements. — Siemens Process Industries and Drives, Spring House, Pa.
