Domesic diaphragm gas meters G1.6, G2.5, G4 are gas volume measurement instrument for coal gas, natural gas, LPG etc. It is designed and developed according to world advanced technology, based on our rich experience, with the merits of small size, light in weight, accurate measurement, high sensibility, low noise, in accordance with Chinese standards GB/T6968-1997 and international standards OIML R31 and EN1359.
● Inner rotary parts of self-lubricating materials.
● Case: steel, inlet & outlet connection, digital display.
● Synthetic rubber for diaphragm with long service life.
● Equipped with anti-theft device to prevent reverse flow of gas through the meter.
● Magnetic transmission for volume indication keeps excellent air tight.
● Rotary valve operation type ensures long time stable, smooth operation and minimum wear.
High quality plastic and stainless metal components, plastic coating inside and outside the cases ensure the meter’s long-life service. |
