ABSTRACT:
The disclosure is directed to a device for monitoring the thermodynamic state of a fluid flowing through a conduit. The device generally comprises a first electromechanical transducer acoustically coupled to the conduit, electronic drive means connected to the first electromechanical transducer to provide a driving electrical signal to the first electromechanical transducer whereby the first electromechanical transducer is oscillated to generate mechanical wave energy for transmission through the fluid flow, and a second electromechanical transducer acoustically coupled to the conduit and arranged in a spaced, acoustically coupled relation to the first electromechanical transducer to receive the mechanical wave energy transmitted through the fluid flow and conduit by the first electromechanical transducer and to convert the received mechanical wave energy into an electrical signal. The electric signal is integrated and conducted to an electronic device which is operable to detect changes in the electrical signal caused by a change in the thermodynamic state of the flowing fluid, to verify the time duration of detected changes in the electrical signal, to record events of detected changes having a time duration of more than a predetermined amount and to sound an alarm when the number of events recorded exceeds a predetermined number. The electronic device is also operatable to sound an alarm when any detected change in the thermodynamic state of the flowing fluid exceeds 30 minutes.
