Products Features
This product uses the pressure difference between the two ends of the air inlet and the air outlet to push the diaphragm and generate continuous movement through the double crank rocker mechanism, so as to measure the gas volume. This product is manufactured in strict accordance with GB/T6968-2011 "Membrane Gas Meter". 2.Paramete This series of products is an independent movement structure. The outer body is stretched from high-quality cold-rolled steel plate, and the all-plastic core body is injection-molded with imported engineering plastics at one time, which reduces the number of parts; the rotary slide valve cover is used, which has a small friction coefficient and high sensitivity; The valve seat and valve cover are made of high-grade phenolic and other synthetic resins, which have higher wear resistance. Well-designed, precisely manufactured and strictly tested gas meters are widely used in the measurement of natural gas, artificial gas, liquefied petroleum gas and other gases.
