Microwave tank-contents level measuring assembly with lens-obturated wall-opening

摘要: A microwave tank-contents level measuring system is housed within a housing having an open end obturated by hyperbolically curved convex-plano fluid impermeable solid dielectric lens providing seal for the tank opening over which installed while collimating outgoing ranging signal and focusing return signal. separate removable cover provides access to electronic components service tank-opening sealing function of not disturbed. transmitting-receiving horn dimensioned positioned on axis with its effective phase center at operating frequency coinciding focal point hyperbolic surface.
