GF Piping Systems (GF) has expanded its automation product line with two new Level Transmitters, incorporating advanced radar sensing technology designed for high accuracy tank level measurement in water treatment applications. The Radar Level Transmitter Type 2290 features non-contact radar technology in a compact, economical unit. Available in a variety of different materials, the 2290’s tank mapping function makes it easy to block out objects like internal pipes, welding seams, stirrers or heating elements. Radar Level Transmitter Type 2291 is designed for continuous level measuring of conductive or non-conductive liquids, pulps or solids. Its radar signal is sent down the probe assembly thereby eliminating interferences caused by low dielectric liquids, heavy fumes, conductive foams or internal tank obstructions. ransmitter model 2290 is available with PP or PTFE antennas while Transmitter 2291 is available with either stainless steel or FEP coated rope, or stainless steel or PFA or PP coated rod.
