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