OverviewQK2000 series gas meter is compact gas meter which is incoporated kroms technology and Qianwei kromschroder tech.

QK2000 series diaphragm gas meter is a new generation product designed and developed by QK//KROM which incorporated the advanced technology and decades of gas meter experience of Germany. with high reliable and hight accuracy as well as long service life which can ensures both low bearing loads and quiet operation. the patented slide control(k-system)synchronizes the operation of the slides with the current flow through the measuring chamber thus achieving and extremely high accuracy of measurement even at the angle of 85 degree. The k-system and the slide structure can minimize mechanical press loss and high accuracy at Qmin. it meets the requirements of national standard GB/T6968-1997 and partly conforms to en1359
