Diaphragm Gas Meter
Description
The steel-cased diaphragm gas meter is designed and manufactured in accordance with EU standards, which have passed EN1359 of NMI laboratory, OIML R137 product standard and MID factory certification; the key components such as membrane and valve system are from Europe. It is characterized by small starting flowrate, wide range, high working pressure and long service life.
Key Strengths
- Low power consumption design
- Anti-reverse ventilation and counting function
- Stable valve control
- High measurement accuracy and sensitivity.
- Stable product performance with more than 20 years market application
- Excellent card compatibility and system integration
- Use special material rubber diaphragm with good durability performance
- Adopt automatic gluing process with good sealing performance
- Adopt surface swimming paint treatment technology with strong anti-corrosion ability and long service life.
- The slide valve movement is rotary moving type, the friction between the slide valve and the slide valve seat is more regular and the wear is even.
- Reserved pulse output interface to provide optional remote set-up
- It can be retrofitted with anti-reversal venting device according to customer requirements
