The diaphragm gas meter features high precision and reliability, with stable flow error and easy control. Its production process and manufacturing techniques have reached internationally advanced levels. The metering chamber diaphragm of this gas meter operates with free oscillation, 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 is characterized by 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; ? Diaphragms made with new technology are durable and provide more reliable metering. The movement and counter are magnetically connected to ensure sealing; ? Upper and lower casings are sealed with gaskets and fastened with bolts for easy maintenance; ? The extended upper and lower casings, along with zinc-plated and spray-coated surface treatment, provide an elegant appearance, glossy color, enhanced rust and corrosion resistance, and significantly reduced weight.
