Description
This water meter is designed for accurate measurement of water flow, with all wetted parts carefully selected to provide high corrosion resistance and long service life. The standard operating temperature for cold water meters is below 30°C (T30), while the MJWM model can safely operate at water temperatures up to 50°C (T50).
The roller is equipped with a special liquid seal that prevents direct contact with water, ensuring clear and stable readings under all operating conditions. The impeller is the only moving part in contact with water, enhancing reliability and minimizing wear. A robust mechanical transmission mechanism ensures extremely high reliability and consistent performance.
An additional inlet filter is integrated at the meter inlet, allowing easy cleaning without disturbing the metering seal. An optional check valve is available to prevent excessive flow.
