The Multi-jet Series Water Meter LXSG-15E2-50E2 is a versatile, high-adaptability flow measurement solution developed and produced by Ningbo Zhiyitong Energy Technology Co., Ltd., a professional high-tech manufacturer with 42,600 square meters of production capacity and over 1.5 million units annual output. This multi-jet meter series, covering DN15 to DN50 (½” – 2”) diameters, supports both cold and hot water measurement, with optional dry-dial, wet-dial, and liquid-sealed configurations. Fully compliant with ISO 4064 standards, it is built to serve the diverse needs of industrial buyers, system integrators, and bulk procurement partners, with full OEM/ODM customization support for global projects.
Unlike single-function cold water meters, this multi-jet hot and cold water meter supports dual-scenario usage, with a temperature resistance of up to 50℃ for cold water and 90℃ for hot water. This all-in-one design eliminates the need for separate product procurement for cold and hot water systems, greatly simplifying inventory management and project sourcing for bulk purchasers.
This customizable residential and industrial water meter offers flexible structural options, including multiple dial types, connection methods, and accuracy classes (Class A and Class B) to match regional standards and project-specific requirements. We provide full OEM/ODM services, from customized parts to branded packaging, to help our business partners build their product lines and meet local market demands.
Made with a high-density brass body, the ISO 4064 compliant flow meter delivers superior resistance to corrosion, pressure fluctuations, and mechanical wear, maintaining stable performance even in harsh industrial and heating system environments. It can withstand a maximum working pressure of 1.0Mpa, with a wide flow measurement range to cover low-flow residential usage and high-flow industrial applications.
With standardized dimensions that align with international pipeline specifications, the DN15-DN50 multi-jet water meter offers excellent interchangeability for global projects. It supports both threaded and flange connections for DN50 models, conforming to GB4216.4 standards, making it suitable for installation in Europe, Africa, the Middle East, Southeast Asia, and more than 20 countries and regions worldwide.
