GUIDED WAVE LIQUID LEVEL MEASUREMENT SYSTEMS AND METHODS

A liquid level measurement system includes a liquid receptacle including a side wall and a guided wave sensor array coupled to the wall. The guided wave sensor array is configured and adapted to emit induced guided waves. A method for detecting a liquid level in a receptacle using a liquid level measurement system includes emitting induced guided waves from a first guided wave sensor array coupled to a wall of a liquid receptacle thereby generating transmitted guided waves. The method includes detecting the transmitted guided waves with at least one of the first guided wave sensor array or a second guided wave sensor array. The method includes determining a liquid level of the liquid receptacle using the detected transmitted guided waves.
