Mechanical water meter

Our single-jet water meters, which are a type of mechanical meters, are designed for measuring smaller water flows and excel in various applications. These meters are widely used in residential water metering and commercial and small industrial settings. They're also effective in monitoring water usage in public facilities and institutions.
