Introduction
In recent years, with the development of technology, the types of gas flow measuring instruments have increased, and the accuracy has been continuously improved. This test
Fixed system table based on JJF1104-2003 "National Metrology Verification System Table Writing Rules" be revised. With JJG
Compared with 2064-1990, in addition to editorial changes, the main technical changes are as follows.
--- Increase pVTt method gas flow reference device;
--- Starting from the principle of device measurement, the measurement standard equipment is divided into the original method of gas flow standard devices and standards
Table gas flow standard device, instead of JJG 2064-1990 in accordance with the level of accuracy of the first-class gas flow
Standard appliances, second-class gas flow standard appliances.
The previous version of the verification system table release situation.
--- JJG 2064-1990 "gas flow measurement equipment verification system."
Gas flow measurement instrument calibration system table
1 Scope
The verification system table is suitable for measuring the amount of gas flow measurement instrumentation within a closed pipeline transfer relationship, including from the base
The volume and export volume to the gas flow measurement standards, gas flow measurement standards, gas flow meter
The relationship between the value of the transmission, the value of the method of delivery and measurement of the value of delivery.
