Hight accuracy ,small compact.comply with en1359 OverviewQK3000 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. 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 //Anticorrosion //Safety and reliability //High-pressure resistance //Backspin stopper, Tamper proof //Easy to develop to smart meter
G1.6S, G2.5S, G4S steel case gas meters are suitable for measuring the flow-rate of natural gas, artificially gas, liquefied petroleum gas and marsh gas G1.6S, G2.5S, G4S steel case gas meters is suitable for measuring the flow-rate of natural gas, artificially gas, liquefied petroleum gas and marsh gas. The measuring group of the meter divided into separate cavities. Process of the central body is injection, with engineer plastic material highly resistant to gas corrosion. Diaphragm is made of high quality polyester fibre with special vulcanization process. Process to manufacture valve and valve seat is compression, material used is bakelite. The valve and valve seat is resistant to wear, having low water absorption, low friction, and is also very stable. This series of diaphragm gas meters have many advantages as follows: polyester plastic measuring group, high quality steel case. This series of meters have 2 type of transmission: magnetic and mechanical. Magnetic transmission has advantages of low friction, good air-tightness performance. Mechanical transmission is very reliable. Two types of register are available for this series of meter: bi-directional and mono-directional. Bi-directional register can read gas flowing in from both outlets and can reduce the gas company measurement loss. Mono-directional register is equipped with anti-reverse device; this type of register will stop reading if gas flows in from opposite direction. The installation of connections can be either by screws or by wielding according to customer's request. This series of products have high sensitivity and accuracy measurement, easy to use and repair, strong anti-corrosion capability and long economic life. The meter performance can fulfill OIML R31-1995standard and EN1359-1998 standard requirement. Main technical parameters
