Name:Gas meter
FEATURES
1. Accurate measurement, the ex-works controlling index for the large and medium flowrates : ±1.2%
2. Rubber diaphragm adopts special material and its durability reach 3000 hours.
3. Adopting automatic glue applying technology and its leak tightness performance reaches 30 KPa.
4. Adopting surface electrophoretic coating treatment technology and it has strong corrosion resistance and long service life.
5. The sliding valve makes rotary displacement motion, there is regular friction and even wearing between the sliding valve and the seat of the sliding valve.
