1. A measurement device, comprising:
- a transmitter configured to transmit an interrogation signal;
a receiver configured to receive the interrogation signal that has been reflected within a container, wherein the received reflected interrogation signal is used to determine a time value that corresponds to a distance traveled by the interrogation signal and the distance traveled by the interrogation signal corresponds to a fill level of the container; and
a protective barrier covering at least the transmitter or the receiver and at least a portion of the protective barrier is configured to be inserted within the container when the measurement device is engaged with the container, whereinsubject to the protective barrier covering the transmitter, the transmitter transmits the interrogation signal through the protective barrier and the transmitter and the protective barrier are separated by a gap, andsubject to the protective barrier covering the receiver, the receiver receives the interrogation signal through the protective barrier.

Abstract
A measurement device includes a transmitter configured to transmit an interrogation signal. The measurement device also includes a receiver configured to receive the interrogation signal that has been reflected within a container. The received reflected interrogation signal corresponds to a fill level of the container. A protective barrier covers at least the transmitter or the receiver. If the protective barrier covers the transmitter, the transmitter transmits the interrogation signal through the protective barrier and the transmitter and the protective barrier are separated by a gap.

20. A method, comprising:
-
transmitting an interrogation signal using a transmitter, wherein the transmitter transmits the interrogation signal through a protective barrier covering at least the transmitter or a receiver and subject to the protective barrier covering the transmitter, the transmitter and the protective barrier are separated by a gap, and at least a portion of the protective barrier is configured to be inserted within a container when a measurement device is engaged with the container; and receiving the interrogation signal that has been reflected within the container, wherein the received reflected interrogation signal is used to determine a time value that corresponds to a distance traveled by the interrogation signal and the distance traveled by the interrogation signal corresponds to a fill level of the container.
