Dynamic Calibration of Automatic Leak-Detection Instruments

Dynamic methods of calibrating automatic leak detectors and manometric monitoring instruments are considered. Attention focuses on chronometric and reduction methods of calibration, which are based on gas emission under pressure through active resistances, employing the frequency principle. High precision is ensured in that the results are independent of the temperature, the humidity, and the gas parameters. Calibration facilitates utilization of the instruments in mass production.
