Weihai flow meter calibration workshop live

The verification method of the device adopts the static quality method and the standard table method. DN15-DN600 covers all standard diameter flow meter calibration. Standard with 4 sets of high precision electronic weighter, the accuracy is better than 1 / 3000; standard table with seven Henghe electromagnetic flowmeter, with an accuracy better than 0.2 class, the repeatability is better than 0.08%; verification medium supply the vessel frequency regulator. The verification process is carried out under the same control of the computer. The extended uncertainty of the device: the static quality method is better than 0.05% (k=2), the standard table method is better than 0.3% (k=2); the flow stability is better than 0.3%; The device can detect the flowmeter type: turbine flowmeter, vortex flowmeter, electromagnetic flowmeter, differential pressure flowmeter etc..

The utility system is composed of a water ring vacuum pump, a stagnant container, a sonic nozzle, a buffer container, a process pipeline, a gas water separator, a frequency conversion system and a control system. 14 kinds of DN15-DN300 can be detected. Device of the flow stability is less than or equal to 0.3%, uncertain degree less than or equal to 0.3%, to receive traffic signal, 4-20mA current signal, frequency and pulse signal, the largest up to 10kHz. The device can detect the turbine flowmeter, vortex flowmeter, thermal mass flowmeter, differential pressure type flowmeter. In line with the national metrological verification regulations JJG643-2003 the standard meter flow standard device verification regulation of "GB / T2624-93 the throttle devices for flow measurement with orifice, nozzle and Venturi tube measurement with round pipe fluid flow" JJG198-94 the velocity type flowmeter verification regulation JJG620-94 the critical flow rate meter verification regulation of "JJG1029-2007 the vortex flowmeter verification regulation JJG1037-2008 the turbine flow meter verification regulation of"
