Leak Rate Detection Using Weight Measurement and Disposable Balloon

The patent replaces expensive, complex helium mass spectrometer equipment with simple, inexpensive components (sealed container, balance, gas storage tank) that can be easily manufactured and disposed of. This achieves comparable detection precision without the high cost and complexity of professional equipment.

The patent substitutes the complex mechanical and electronic system of a helium mass spectrometer with a simple mechanical weighing system. Instead of using sophisticated spectral analysis equipment, the invention uses a balance to measure weight changes caused by gas leakage, achieving detection through basic mechanical measurement.

The patent employs inexpensive, easily manufactured components such as a sealed container (which can be a simple latex balloon), a standard balance, and a gas storage tank. These components cost a fraction of a helium mass spectrometer while achieving sufficient detection precision for general applications.

The patent creates a simplified copy of the leak detection function using basic components rather than replicating the complex helium mass spectrometer system. Instead of copying the sophisticated detection mechanism, it uses an alternative approach (weight measurement) that achieves the same goal at much lower cost.

The patent creates a self-service detection system where the sealed container itself serves as both the test object and the measurement indicator. The system automatically indicates leakage through weight changes on the balance without requiring complex operational procedures, skilled operators, or sophisticated data analysis.

The patent replaces complex electronic control and data processing systems with simple mechanical weighing. The balance provides direct, intuitive measurement of leakage through weight changes, eliminating the need for complex operational procedures required by professional equipment while maintaining sufficient measurement precision.
