Description
This water meter is designed for accurate and reliable measurement of water flow, with all materials in contact with water carefully selected for high corrosion resistance. All plastic raw materials used are 100% new and not secondhand, ensuring durability and long service life.
The standard operating temperature for cold water meters is below 30°C (T30), while the MJ-LDP model can safely operate at water temperatures up to 50°C (T50).
The roller utilizes a special liquid seal that prevents direct contact with water, providing clear and stable readings under all operating conditions. The impeller is the only moving part in contact with water, which enhances reliability and minimizes mechanical wear. A robust mechanical transmission mechanism ensures extremely high reliability and consistent performance.
An additional inlet filter is installed at the meter inlet, allowing easy cleaning without disturbing the metering seal. An optional check valve is available to prevent excessive flow.
