Abstract
An ultrasonic liquid sensor for detecting liquid in a tube having sidewalls includes a first intermediate mounting plate held in physical communication with a first sidewall of the tube, a second intermediate mounting plate held in physical communication with the second sidewall of the tube. The plates are configured to allow the ultrasonic signal to pass therethrough. The sensor also includes a first and a second transducer element. The first and second transducer elements are mounted to the intermediate mounting plates and are configured to receive the ultrasonic signal passing through the sidewalls of the tube as well as the intermediate mounting plates to determine the presence or absence of liquid in the tube. The sensor can be enclosed in a self-contained unit and a support assembly can be used and formed of metal material or non-metal material to interface with the sensor and a secondary circuit.
