Abstract
Apparatus and method of use where the apparatus is configured to be attached to and/or located adjacent to a fluid conduit in use, said apparatus including a sensor assembly including at least one sonic or vibration receiving means. The sonic or vibration receiving means is configured to receive sound or vibrations propagating through and/or originating from said fluid conduit and/or fluid contained in the same.
Claims6
An apparatus configured to be attached to and/or located adjacent to a fluid conduit in use, where the apparatus includes a sensor assembly including at least one of a sonic sensor or a vibration sensor characterised in that the at least one of the sonic sensor or the vibration sensor is configured to respectively receive a sound or a vibration propagating through and/or originating from the fluid conduit and/or a fluid contained in the fluid conduit.
An apparatus, comprising:
- a clamp including a first contact portion and a second contact portion that are spaced apart to define a first region, wherein the clamp includes at least one of (i) a jacket that circulates a coolant adjacent to the first region or (ii) a thermoelectric module that enables cooling of the first region;
- an ultrasonic transducer mounted on the clamp;
- a transmitter circuit electrically connected to the ultrasonic transducer;
- a receiver circuit electrically connected to the ultrasonic transducer;
- a microcontroller electrically connected to the transmitter circuit, the receiver circuit, and at least one of the jacket or the thermoelectric module,
- wherein, when the clamp clamps a wall of a conduit at a second region via the first contact portion and the second contact portion, the microcontroller enables (a) the transmitter circuit to drive the ultrasonic transducer to transmit a quantity of ultrasonic energy into the wall, (b) the ultrasonic transducer to convert a reflection of the quantity ultrasonic energy into an electrical signal, (c) the receiver circuit to receive the electrical signal from the ultrasonic transducer, (d) the receiver circuit to provide the electrical signal to the microcontroller, (e) the microcontroller to determine an amplitude value from the electrical signal, and (f) the microcontroller to control an operating parameter including at least one of a flow rate of the coolant through the jacket or a level of electrical power supplied to the thermoelectric module as a function of the amplitude value whereby at least one of the jacket circulates the coolant adjacent to the wall at the flow rate or the thermoelectric module cools the wall at the level of electrical power to enable a fluid to be frozen in the second region and formation of an ice plug in the second region to be confirmed based on the electrical signal.
