Patent number: 11754544Abstract: Apparatuses, methods, and systems for accurate measurement of the bulk modulus of a fluid in a fluid distribution system. An apparatus comprises a pipe, a first endcap, and a second endcap defining a cylindrical cavity, a means for filling the cylindrical cavity with a fluid sample, and a vibrational sensor coupled to an end plate of the second endcap and communicatively connected to a water property measurement system. The vibrational sensor is operable to, subsequent to the filling of the cylindrical cavity with the fluid sample, send a signal representative of sensed vibrations in the end plate of the second endcap to the water property measurement system while an end plate of the first endcap is excited. The water property measurement system computes a frequency response function from the signal and determines a bulk modulus value for the fluid sample based on the frequency response function.Type: GrantFiled: February 26, 2021Date of Patent: September 12, 2023Assignee: Mueller International, LLCInventors: Sebastien Perrier, Bruce Robertson, Valentin Mircea Burtea

Patent number: 11726064Abstract: Methods, systems, and computer-readable storage media for accurate time delay estimation using coherent averaging. A plurality of out-of-bracket acoustical impulses are generated in a pipe segment of a fluid distribution system. Signal data representing the acoustical impulses sensed at two locations along the pipe segment are recorded. Precise timings for the generation of the acoustical impulses are obtained, and the acoustical impulses in the signal data recorded from the first location are averaged based on the precise timings to produce a near-sensor average impulse. Similarly, the acoustical impulses in the signal data recorded from the second location are averaged based on the same precise timings to produce a far-sensor average impulse. A time delay between arrival of the plurality of out-of-bracket acoustical impulses at the first and second locations is estimated from the timing of the near-sensor average impulse and the far-sensor average impulse.Type: GrantFiled: July 22, 2020Date of Patent: August 15, 2023Assignee: Mueller International LLCInventors: Valentin Mircea Burtea, Sebastien Perrier, Bruce Robertson

Patent number: 11609348Abstract: Methods, systems, and computer-readable storage media for performing high-resolution assessment of the condition of pipes of a fluid distribution system using in-bracket excitation. Acoustical impulses are generated in a pipe at two excitation locations along the pipe while signal data is recorded from two acoustic sensors, at least one of the excitation locations being located in-bracket of the two acoustic sensors. A first time delay between the arrival of the acoustical impulses at the two acoustic sensors is computed from the signal data recorded during generation of the impulses at the first excitation location, and a second time delay between the arrival of the impulses at the two sensors is computed from the signal data recorded during generation of the impulses at the second excitation location.Type: GrantFiled: December 29, 2020Date of Patent: March 21, 2023Assignee: Mueller International, LLCInventors: Bruce Robertson, Valentin Mircea Burtea, Sebastien Perrier, Joseph Butterfield

Publication number: 20230017820Abstract: Methods, systems, and computer-readable storage media for providing high-resolution assessment of the condition of pipes of a fluid distribution down to the individual pipe stick. An acoustic sensor is placed in acoustical communication with a pipe at one end of a target segment. An acoustical wave is generated in the pipe at a first out-of-bracket excitation location while signal data is recorded from the acoustic sensor. Timing information regarding the arrival at the acoustic sensor of reflections of the acoustic wave from pipe joints in the target segment is extracted from the recorded signal data, and a time delay between reflections from consecutive pipe joints is computed. An acoustic propagation velocity in a pipe stick between the consecutive pipe joints is then computed based on the time delay and a length of the pipe stick. A condition of the pipe stick is determined based on the computed acoustic propagation velocity.Type: ApplicationFiled: July 19, 2021Publication date: January 19, 2023Inventors: Valentin Mircea Burtea, Joseph Butterfield, Bruce Robertson, Sebastien Perrier
