Precision Performance for Residential Water Metering
This DN15 volumetric water meter is designed for accurate and stable water consumption measurement in residential and light commercial applications. Built with advanced piston displacement technology, it delivers reliable registration even at very low flow conditions, making it ideal for precise billing and efficient water management. With an impressive Class B (R400) accuracy level and a low starting flow of 2.08 L/h, the meter can capture small usage volumes that conventional meters may miss. Its horizontal installation design and threaded BSP G3/4B connection also make integration simple for standard pipeline systems.
Durable Construction for Demanding Environments
Engineered for long-term performance, this model features a dry dial and hermetically sealed register to keep the display clear and protected from moisture, dirt, and condensation. The robust IP68 protection class ensures dependable operation in humid, flooded, or underground installation conditions. For added security, the meter includes anti-magnetic protection, helping reduce the risk of tampering and preserving measurement integrity. Compliant with ISO 4064, it combines durability, accuracy, and trusted quality in one compact solution.
