Working Theory and Features:
- Measures gas volume by using pressure difference between inlet port, outlet to push membrane, and double crank incessant movement
- Material: Top quality cold-rolled steel plate and imported high quality plastic
- Used for one-shot forming measuring unit with parts reduction
- Eddy slide valve, low friction, and high sensitivity
- Wearable synthetic resin for material of valve base and lid
- GS series with well-connected design, production, and test
- Widely used for measurement of natural, artificial gas, and liquefied petroleum
Transport and storage:
- Upstanding and waterproof
- No thwart, inversion and bumping
- Storage temperature: -20 to 50° C and dryness place
