Shanghai Welltech Instrumentation
Co., Ltd. Testing Laboratory

Shanghai Welltech flow monitoring center was established on June, 2002,which has invested 
several billions Yuan, covers an area of 4000 square meters

Monitoring center has a capacity of 4 flow standard device and a total of 8 pipeline, there is 3 sets of the variable water flow standard device of dynamic volumetric method, 4 calibration line, maximum standard flow is 25000m3/h, the total uncertainty of system is better than 0.037% and applied for a patent for invention; there is 1 set of flow standard device of high slot voltage weighing method, 4 calibration line, the total uncertainty of system is better than 0.015%. It can check DN3 ~ DN3800 all kinds of diameter of flowmeter, for example: electromagnetic flowmeter, mass flowmeter and so on. It is a water flow standard device which has the biggest current calibration diameter scope, the highest degree of automation, and the highest degree of accuracy of similar equipment calibration precision.
Shanghai Welltech flow monitoring center is according to CNAS (China National Accreditation Service for Conformity Assessment) and established a quality manual and program files, Shanghai Welltech flow monitoring center approved by the CNAS is become the national level’s monitoring center. We will be in line with the standard of behaviour which is "fair, objective and precise" and provides the high-quality service wholeheartedly for the general customers.
