Problems solved by technology

[0007] Due to the limited conditions of the production site, the on-site gas distribution process is generally carried out under working conditions, and the temperature of the working conditions and standard conditions will generally be different, resulting in the concentration of the standard gas configured by the standard gas distribution instrument. The working condition concentration under this working condition deviates from the standard condition concentration under the standard condition required for calibrating the gas analysis system, which will cause certain errors when using the standard gas to calibrate the gas analysis system

Abstract

The application discloses a standard gas distribution control method and system and a standard gas distribution gauge.The method comprises the specific steps: acquiring preset condition concentration value of standard gas under current conditions, using a temperature sensor to acquire condition temperature under current conditions, calculating the condition temperature by an ideal gas equation to obtain a concentration correction coefficient, and correcting and calculating the condition concentration value by the concentration correction coefficient to obtain a standard concentration value of the standard gas under standard condition.The condition concentration under working condition can be corrected into the standard condition concentration under standard condition through the above conversion, and an operator can calibrate a gas analysis system according to the standard condition concentration value, thus avoiding errors generated during calibrating of the gas analysis system.

Description
