1. A level gauge comprising:
- at least one antenna configured to transmit wireless signals towards a material in a tank and to receive wireless signals reflected from the material in the tank; and
a housing comprising;
an outer annular region having an inner perimeter;
a raised annular rim within the inner perimeter of the outer annular region;
an angled annular region that extends between the inner perimeter of the outer annular region and the raised annular rim and that is angled toward a longitudinal centerline of the housing away from the outer annular region; and
a concave portion within the raised annular rim, the concave portion forming a crater within the housing;
wherein the at least one antenna is configured to transmit and receive the wireless signals through the concave portion of the housing.

Abstract
A level gauge includes at least one antenna configured to transmit wireless signals towards a material in a tank and to receive wireless signals reflected from the material in the tank. The level gauge also includes a housing having an outer portion, a raised rim within the outer portion, an angled portion that extends between the outer portion and the rim, and a concave portion within the rim. The concave portion forms a crater within the housing. The at least one antenna is configured to transmit and receive the wireless signals through the concave portion of the housing.
