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
