Evaluation and Expression of Uncertainty in Measurement
JJF1225-1990 1.6 ~ 146 m3/h water flow reference operating specifications
3 Terms and definitions
3.1 The best measurement ability (calibrationmeasurementcapability)
The highest level of calibration measurement usually provided to the user, which is expressed as an extended uncertainty with a factor of k = 2.
3.2 volume method liquid flow standard device (liquidflowstandardfacilitiesbyvolume)
To measure the amount of liquid volume in the work load cell over a period of time to calculate the flow rate is the principle of flow
Device.
3.3 mass method liquid flow standard device (liquidflowstandardfacilitiesbyweighing)
The method of calculating the flow rate by weighing the liquid in the tank over a period of time is the principle flow device.
3.4 The original method of liquid flow standard device (primarystandardfacilitesofliquidstandard)
Is the quality of liquid flow standard device and volumetric liquid flow standard device collectively, also known as liquid flow standards
Device.
3.5 sub-group combination (combinatorialmethod)
Index values from the combination of other values, and other quantities such as length, quality, respectively, by the magnitude of the previous level
Quasi-passed from the value of the transfer method, such as the original method of liquid flow rate standard device is the use of sub-combinations of the parties
Act
3.6 comparative law (comparativemethod)
Means to pass the direct comparison of the amount of value transfer method, such as the use of standard meter test device was seized flow meter
The value of the transfer method.
3.7 indirect measurement method (indirectmethod)
Means to measure the value of the volume through other measures of value transfer method, such as the standard orifice size measurement.
3.8 Syntheticalmethod
Refers to a combination of one or more of the above methods of value transfer method.
