The diaphragm gas meter features high precision and reliability, with stable flow error and ease of control. Its production technology and processing methods have reached internationally advanced levels. The diaphragm in the metering chamber swings freely without mechanical stops, offering light bearing load and low noise. The patented sliding control system works in coordination with the valve to ensure accurate measurement. Its low flow resistance coefficient also makes it insensitive to impurities. This meter boasts an aesthetically pleasing design, high sensitivity, accurate measurement, stable performance, safety, reliability, and a long service life. Main Features: ? Wide applicable flow range, high sensitivity, accuracy, and reliability; ? Stamped metering chamber housing and anti-corrosion surface treatment ensure strength and corrosion resistance; ? Diaphragm made with new technology ensures durability and reliable measurement; magnetic transmission connects the movement and counter, ensuring sealing; ? Upper and lower casings are sealed with gaskets and bolted for easy maintenance; ? Extended upper and lower casings with zinc-plated and spray-coated surfaces provide an elegant appearance, glossy color, enhanced rust and corrosion resistance, and significantly reduced weight.
