SITRANS FS290

Portable Clamp-on Ultrasonic Flow System

SITRANS FS290 portable ultrasonic flow meter system is a battery- or mains-powered system, making it the perfect tool for monitoring volumetric flow in pipes that may be too remote for typical measurement systems. The FST090 system contains the battery-powered transmitter and SITRANS FSS220 clamp-on transducers and mounts. The transducers are quickly and easily installed or relocated, as needed, on the outside of a pipe without the need for any process interruptions or plant downtime. Quick, easy, portable and self-contained, the FS290 is the ideal tool for your testing and flow evaluation needs.
