  • Patent number: 7134315
    Abstract: An improved pulse radar level sensing gauge for insertion into a storage or processing tank includes a housing; a probe cover comprising a sealing flange; and a probe for sensing electrical and mechanical properties, positioned at least partly below the sealing flange of the probe cover. The unitary flange of the probe cover aids in preventing contamination of the tank contents by foreign substances. Additionally, the location of the probe at least partly below the sealing flange of the probe cover improves the accuracy of the level sensing gauge by reducing disruption of the properties by the tank following the attachment of the level sensing gauge to the tank.
