OverviewQK4000 BK series gas meter is our company introduction of the kroms original technology.which incorporate both innovative features and Elsters gas measurement know-how of many decades. In measuring unit the diaphragms are moving stress free without mechanical stops. This ensures low bearing loads and quiet operation. High-grade materials and components as well as the patented K-system ensure a high quality standard and a long service life. The K-system synchronizes the operation of the slides with the current flow through the measuring chamber thus achieving minimum flow channels and an extremely high accuracy of measurement. Due to the small slides, they are not susceptible to contamination (RPF of 0.90 to BS4161). Error curve of measuring units are adjusted by K-system. Robust design. They meet requirements of GB/T6968-1997 and EN1359.Main Features //Fire resistant up to 0,1 bar to DIN En 1359 //High accuracy and long-term stability //Error curve adjustable //Pulse magnet //Low noise //RPT=0.8 is not sensitive to the impurity //Stadium diaphragm //Independence measuring unit //Powder coating, light grey //Hight Anticorrosion //Safety and reliability //High-pressure resistance //Backspin stopper, Tamper proof //Easy to develop to smart meter
