Two new models of level transmitter — Type 2290 and 2291 (photo) — have been designed for use in challenging tank applications where other contacting or non-contacting measuring principles face limitations. Type 2290 is a compact non-contact radar level transmitter that is available in a variety of materials to resist very corrosive environments. With its tank mapping function, it is easy to block out objects like internal pipes, welding seams, stirrers or heating elements. Type 2291 is a guided-radar level transmitter that provides measurement even in very turbulent process vessels. The radar signal is sent down the probe assembly, eliminating the interferences caused by low dielectric liquids, heavy fuming, slightly conductive foams or internal tank obstructions. Both transmitters are suited for applications in harsh environments, and communication can be either via HART or analog. — GF Piping Systems Ltd., Schaffhausen, Switzerland
