Description

� Compliance with requirements of GB/T ********7 and OIMLR *1, optimized design, long service life. � Separate core design avoids effectively impacts of impurities and makes the meter applicable to a wide range of gas qualities. � Internationally advanced spin valve structure is adopted, thus the meter turns smoothly, and is of small friction factor and sealed good. � Core metering turning is delivered to the counter outside the case through �magnetic driving�. Flexible driving and reliable sealing. � Metering diaphragm swings freely. Smooth limit transition. No turning point and dead point. Smooth operation, light load and low noise. � Core structure is simplified, main parts are integrated through moulding, small part quantity and good precision unification. � Quality cold roll sheet is adopted for the case with a thickness of 1mm while stainless steel pressure seal ring is used to seal the upper and bottom cases, offering strong pressure resistance and reliable integrated sealing. � High severity engineering plastics is adopted for the interior driving mechanism, parts of shaft type are made of stainless steel, offering strong corrosion resistance. � Advanced technology. Advanced technological equipments are adopted to assure assembly quality. Advanced ultrasonic welding and hot plate welding are adopted for the core to assure quality. � Plastic spraying is adopted for the case surface, making the appearance aesthetic and providing good corrosion resistance. � A wide variety of structures and units that protect from destruction.
