The verification method of this device adopts static mass method + standard table method. Covers the verification of all standard DN15-DN600 pipe diameter flow meters. The standard instrument uses 4 high-precision Toledo electronic scales with accuracy better than 1/3000; the standard meter uses 7 Yokogawa electromagnetic flowmeters with accuracy better than 0.2 level and repeatability better than 0.08%; the container for verification medium supply is used Variable frequency voltage regulation. The verification process is implemented under the same control of the computer. Uncertainty of expansion of the device: static mass method is better than 0.05% (k = 2), standard meter method is better than 0.3% (k = 2); flow stability is better than 0.3%; the device can detect flowmeter types are: turbine Flowmeter, vortex flowmeter, electromagnetic flowmeter, differential pressure type flowmeter, etc.

The device is composed of a water ring vacuum pump, a stagnation container, a sonic nozzle, a buffer container, a process pipeline, a gas-water separator, a frequency conversion system, a control system, and the like. It can detect 14 kinds of caliber DN15-DN300. The flow stability of the device is ≤0.3%, and the uncertainty is ≤0.3%. It can receive flow signals, current signals 4-20mA, frequency and pulse signals, up to 10KHz. This device can detect turbine flowmeter, vortex flowmeter, thermal mass flowmeter, differential pressure flowmeter, etc. Conforms to the national verification regulations JJG643-2003 "Standard meter method flow standard device verification regulations" GB / T2624-93 "Flow measurement throttling device orifice orifice and venturi tube measurement of fluid flow filled with round tubes" JJG198-94 "speed type Flowmeter Verification Regulations "JJG620-94" Critical Flowmeter Verification Regulations "JJG1029-2007" Vortex Flowmeter Verification Regulations "JJG1037-2008" Turbine Flowmeter Verification Regulations "
