Abstract

In order to meet the requirements of rapid on-site verification / calibration of flow meters in our country’s natural gas measurement field, we have jointly developed a movable gas flow testing device equipping with critical flow venturi nozzle. According to actual needs the device will be used in the different lab.In order to ensure the uncertainty of the device can meet the requirements of customers,the designer should fully demonstrates and considers the design in selecting the most suitable temperature and pressure sensor, and the processing of calculus.From technical point, we should control the possible impact on the measurement results of the movablegas flow testing device caused by environmental changes.

Keywords

Calibration and testing on the site; Critical flow venturi nozzle; measurement uncertainty; Correlation analysis ; Optimize the calculus method
