Wide Range R400 Ultrasonic Water Meter for Water Supply

Product Overview

Our wide range R400 ultrasonic water meter is a next-generation smart metering solution engineered for municipal water supply, residential water management, and water resource conservation projects. Utilizing advanced time-difference ultrasonic measurement technology, this DN15-DN40 ultrasonic water meter calculates water flow velocity by detecting the propagation difference of ultrasonic signals in water, eliminating the need for mechanical impellers and moving parts that plague traditional mechanical water meters. Designed exclusively for clients in the water supply and construction industries, it solves core industry pain points including small flow undercounting, mechanical wear, high maintenance costs, and low metering accuracy. With a maximum range ratio of up to R500, MID certified ultrasonic water meter compliance, and full smart connectivity, it is the ideal choice for smart water system upgrades, large-scale residential projects, and municipal water supply network modernization.

Key Features & Core Advantages

Industry-Leading Wide Range Ratio & Ultra-Precise Micro-Flow Metering

This R400 R500 wide range ratio water meter delivers an industry-leading range ratio of up to R500, with a minimum starting flow rate as low as 0.005m³/h, enabling accurate measurement of even micro water drops. It eliminates the long-standing "small flow undercounting" issue of traditional mechanical meters, with U0/D0 flow sensitivity ultrasonic water meter technology that is unaffected by flow field disturbances, ensuring consistent Class 2 accuracy across the entire flow range. It supports bidirectional flow measurement, with 0.001L calibration resolution for unrivaled metering precision, helping water utilities reduce non-revenue water (NRW) and improve revenue recovery.

Zero Mechanical Wear & Low Total Cost of Ownership

With no moving parts or mechanical impellers, this no mechanical wear ultrasonic water meter has zero risk of mechanical abrasion, jamming, or performance degradation over time, drastically reducing maintenance and replacement costs for operators. It features an ultra-low power consumption design with a built-in DC 3.6V lithium battery, delivering a continuous service life of over 10 years, with low pressure loss that reduces water supply system energy consumption. It also integrates intelligent functions including leakage detection, low voltage alarm, and tamper-proof monitoring, ensuring long-term stable operation with minimal on-site maintenance.

Full-Environment Adaptability & Global Compliance

This IP68 waterproof ultrasonic water meter features a fully sealed IP68 protection rating, making it dust-tight and permanently submersible, suitable for harsh installation environments including underground pipe wells, high-humidity basements, and outdoor municipal pipe networks. It operates reliably in ambient temperatures from -25℃ to 70℃ with 100% humidity tolerance, and is fully compliant with EU MID certification, meeting international metering standards for global project deployment. It supports full-angle installation, with no strict straight pipe requirements, making it easy to install in tight spaces.

Multi-Mode Smart Communication for Smart Water Management

The meter offers a full range of optional communication protocols including Modbus, RS485, NB-IoT, 4G-Cat.1, OCT Pulse, and 4-20mA, making it a highly versatile NB-IoT smart ultrasonic water meter for modern smart water systems. It seamlessly integrates with cloud-based water management platforms, enabling remote automatic meter reading, real-time leakage monitoring, consumption data analysis, and centralized billing management. It eliminates manual meter reading costs, improves operational efficiency, and enables data-driven water resource management for water utilities and municipal authorities.
