Application
FMJC type gas meter adopts French high quality rubber diaphragm, it is suitable for domestic measuring flowrate of natural gas, town gas and L.P.G. etc.
Features
The diaphragm of this type gas meter adopts new ECO rubber material, it has stronger corrosion resistance against medium and better flexibility than ordinary diaphragm which adopts butadiene-acrylonitrile rubber, it is possessed of better elasticity and the gas meter’s measuring accuracy and durability is improved.
