K-TEK”s MT5000 Series guided-wave radar level transmitters is designed for use in a variety of harsh environments, such as oil & gas processing and power generation. The level transmitters and the MT5100 level and interface transmitter feature an integrated graphic display for quick and easy viewing of waveform screens. A concentric waveguide directs the radar beam, alleviating divergence problems and echoes from tank walls and surrounding structures. In addition, the devices are unaffected by variations in specific gravity due to temperature or pressure changes, and accurate level measurements are provided even with widely varying temperatures and pressures up to 5000 PSI (344 bar) or 800 F. The MT5100 also features a patent-pending interface weak-signal detector that is able to detect the presence of a rag layer before emulsions can become a problem.
