Sound Velocity Sensor

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention describes a sound velocity sensor designed to measure the speed of sound in fluids (gases or liquids) within a pipeline. This compact sensor features a chamber with ultrasound transducers and can be integrated directly inside a fluid-carrying pipe. The sensor has a mechanism to isolate fluid in a measurement chamber using an electromagnet and spring, enabling accurate, in-line measurement of fluid properties such as sound speed, which correlates with density and specific heat capacity.

Use CasesContent extracted from patent full text and abstract with AI.

• Real-time monitoring of fluid composition in industrial pipelines (e.g., gas, refrigerants, heat transfer fluids)
• Density and/or heat capacity measurement in heating and cooling circulatory systems
• Quality and process control in chemical or energy industries
• Leak detection or anomaly detection in pipeline systems
• Integration in smart flow metering or process automation systems
• Research and laboratory analysis for fluid characterization

BenefitsContent extracted from patent full text and abstract with AI.

• Compact, space-saving design allowing full integration into pipelines (in-line installation)
• Simple and robust construction, reducing mechanical complexity and points of failure
• Can be applied to both high and low temperature environments
• Real-time and in-situ measurement capability without the need for external sampling
• Handles potentially contaminated or chemically aggressive fluids due to robust diaphragm and materials
• Low pressure drop and minimal interference with pipeline flow
• Improved safety and process control by allowing for continuous monitoring
• Flexible operation: sensor can be isolated from the flow for measurement, minimizing disturbance
