introduction
This procedure based on JJF1002-2010 "national verification procedures to write the rules," written in conjunction meter testing device
Set characteristics and development situation in our country, will JJG 164-2000 "liquid flow standard device" in the meter testing device
Set a separate part revision procedure Except as noted in section referenced JJG 164-2000 verification method, this Regulation
JJG 164-2000 process will replace the meter calibration device the content. For the test meter method should be in accordance with meter means
According to the relevant provisions JJG 643 "standard table method flow standard device" execution. Furthermore, this regulation is aimed primarily at cold
Shui meter testing equipment.
Compared with JJG 164-2000, in addition to editorial changes this procedure outside of the main technical changes are as follows.
--- Increased introduction, describes the procedure as amended in accordance with revised front and rear major technological changes, the alternative procedures
Previous editions, etc;
--- Adjust the classification of water meter device, the meter calibration device into the collection method, flow method and standard time
Table method;
--- Clear that only a level of accuracy, 0.2;
--- Increasing the stability of the apparatus flow requirements;
--- Cancel the effect of the start and stop of the test;
--- Refine the general technical requirements for metal gauges, the length of the scale, the minimum primary indication, etc;
--- Increase the quality of the law means the density measurement requirements;
--- Timer simplifies verification requirements;
--- Verification in accordance with the volume of work is the need to re-engraved lines are divided into two kinds of cases, were provided for verification within
Content and methods;
--- Adds checks for automatic meter reading equipment;
--- Modify the instantaneous flow indicator verification requirements, instead of checking the flow rate setting means;
--- Weighing modified test method, an increase of tare, use lower limit and other requirements, reducing the test point,
You can test only the loading process;
--- Increased piston meter verification device verification method;
--- Increased use of the instrument in the inspection requirements in test cycles;
--- Modified calibration certificate/test results in the notice page format;
JJG 1113-2015 previous version "water meter testing equipment," the release case.
--- JJG 162-85 "water meter and test equipment";
--- JJG 164-2000 "liquid flow device."

3 Terms
3.1 collection method colectionmethod
The verification process will be flowing through the meter in water collecting in one or more containers, determined by weighing method or the volumetric method
Water.
3.2 Flow time method flowrateandtimemethod
Flowing through the meter in the certification process to determine the amount of water flow through the measurement results and time. Prescribed by
Carried out within the time one or more times repeated measurements of the flow to achieve, but to avoid the beginning of the test and the end of the non-constant
Constant flow area instantaneous flow measurement.
3.3 gauge setting mechanism volumepresetdevice
Gauges installed in the photoelectric or inductive electrical contacts and other water level sensor, measured in the water level rises to a preset position
When issuing a feedback signal to the device operating system to stop the flow of media devices, automatic operation and standard volume value
Determination.
