The Ultrasonic Water Meter DN50 DN200(industrial ultrasonic water meter) bridges the gap between small residential meters and large municipal models, offering precise flow measurement for medium-scale commercial, industrial, and municipal applications. Designed for pipelines with nominal diameters from 50mm to 200mm, these ultrasonic meters utilize transit-time technology to achieve accurate measurement without moving parts, ensuring durability and long-term performance. Compliant with industry standards, the meter delivers ±2% accuracy in high-flow regions (Q2 to Q4) and ±5% accuracy in low-flow regions (Q1 to Q2), making it suitable for both billing and operational monitoring. With maximum working pressures available in PN10, PN16, and PN25 configurations, the meter adapts to various system requirements, from commercial buildings to industrial facilities. The DN50 model handles flow rates up to 25 m³/h, while the DN200 model accommodates up to 400 m³/h, providing versatile solutions for diverse medium-flow applications. Its robust construction and intelligent design make it a reliable choice for water utilities, facility managers, and industrial operators seeking accurate, low-maintenance flow measurement.
Engineered with a wide measurement range, the DN50-DN200 meters maintain accuracy across varying flow conditions, from minimum night flow monitoring to peak demand periods. This versatility eliminates the need for multiple meter sizes in complex systems, simplifying inventory and installation.
Constructed with high-grade materials including ductile iron or brass housings (depending on model) and corrosion-resistant internal components, the meters withstand harsh water conditions and environmental factors. The rugged design ensures reliable operation in both indoor and outdoor installations.
With a pressure loss coefficient optimized for medium flow rates (△p values tailored to each diameter), the meters minimize energy consumption for water pumping and distribution. This efficient design reduces operational costs while maintaining system pressure stability.
Equipped with optional communication interfaces including M-BUS and RS-485, the meters enable integration into building management systems or municipal monitoring networks. This allows for remote data collection, consumption analysis, and early leak detection.
The meters feature large, easy-to-read displays showing cumulative consumption, current flow rate, and status indicators. Infrared ports enable convenient on-site data collection using handheld devices, complementing remote monitoring capabilities for comprehensive management.
Shopping centers, hotels, and office complexes utilize DN50-DN100 meters to monitor total water consumption, manage costs, and identify usage patterns across multiple tenants or facility zones.
Manufacturing plants, food processing facilities, and warehouses install these meters to track water usage for production processes, cooling systems, and facility services, supporting resource optimization and regulatory compliance.
Water utilities deploy DN100-DN200 meters in district metering areas, sub-divisions, and commercial districts to monitor distribution network performance, detect leaks, and manage pressure in secondary supply lines.
Schools, hospitals, and sports complexes use the meters to track water consumption for facility management, budget planning, and implementation of water conservation measures across multiple buildings or campus areas.
Medium-scale agricultural operations, golf courses, and public parks utilize the meters to monitor irrigation water usage, ensuring efficient distribution and compliance with water rights and usage regulations.
The meters' robust construction, wide pressure tolerance (up to PN25), and versatile flow range make them adaptable to diverse environments, from office buildings with stable pressure to industrial facilities with varying demand patterns and water quality conditions.
Unlike mechanical meters with rotating components that require periodic servicing, these ultrasonic meters have no moving parts, reducing maintenance requirements by approximately 70%. Routine checks are limited to visual inspections and occasional communication testing.
Yes, specific models are designed for vertical installation with proper flow direction (upward) to ensure accurate measurement. Consult the installation manual for orientation guidelines and recommended straight pipe requirements for vertical installations.
