Ultrasonic Water Meter（DN15-DN40)

Product Overview

The Ultrasonic Water Meter DN15 DN40 represents a advanced solution for accurate water consumption measurement in residential and small commercial settings. Designed to meet the rigorous standards of ISO 4064 Class C, these meters provide reliable volumetric measurement of cold portable water flowing through pipelines with nominal diameters of 15mm to 40mm. Unlike traditional mechanical meters, this ultrasonic model utilizes state-of-the-art transit-time technology to calculate water flow without moving parts, ensuring long-term durability and consistent performance. The meter features a robust brass body construction paired with a screw-type dry dial, combining corrosion resistance with easy readability and simplified maintenance. Ideal for both new installations and retrofits, the DN15 DN40 ultrasonic water meter delivers precise measurement across a wide range of flow rates, making it a preferred choice for water utilities, property managers, and homeowners alike.

Product Features

Superior Measurement Accuracy

Compliant with ISO 4064 Class C standards, this water meter maintains exceptional accuracy with a maximum allowable error of only ±5% at low flow rates and ±2% at high flow rates. This precision ensures fair billing and accurate monitoring even during minimal water usage periods, such as overnight or low-usage hours in residential settings.

Durable Construction

The meter's high-quality brass body provides excellent resistance to corrosion and mechanical damage, ensuring a long service life even in challenging water conditions. The dry dial design eliminates direct contact between the measurement mechanism and water, preventing fogging, condensation, and sediment buildup that can obscure readings in traditional wet dial meters.

Wide Operational Range

Engineered to handle water temperatures up to 50°C, the DN15 DN40 ultrasonic water meter accommodates various residential and small commercial applications. Its low start-up flow rate capability ensures accurate measurement even for minimal water usage, such as trickling faucets or small appliances, eliminating the "under-measurement" common in less sophisticated meters.

Pressure Resistance

With a pressure class rating of 1.6 MPa (16 bar), this water meter safely operates under standard municipal water pressure conditions. The pressure-loss class is optimized for each size, with DN15/DN20 models featuring δp 40 and DN25/DN32/DN40 models designed with δp 63, ensuring minimal impact on overall water pressure in the system.

Applications

Residential Buildings

Perfectly suited for single-family homes, the DN15 model provides accurate measurement for typical household water consumption patterns, including drinking water, bathing, cooking, and lawn irrigation systems.

Multi-Unit Apartments

The range of sizes from DN15 to DN40 makes these meters ideal for apartment complexes, allowing property managers to accurately monitor individual unit consumption for fair billing and leak detection.

Small Commercial Establishments

Cafés, small restaurants, and retail spaces benefit from the DN25-DN40 models, which handle higher flow rates required for commercial appliances while maintaining precise measurement for cost control.

Pure Water Systems

Beyond standard tap water, these ultrasonic meters are specially calibrated to accurately measure pure water flows, making them suitable for laboratories, water filtration services, and bottled water facilities.

FAQ

What makes ultrasonic technology better than mechanical meters?

Ultrasonic meters have no moving parts, eliminating wear and tear that can affect mechanical meter accuracy over time. This results in longer service life, reduced maintenance needs, and consistent measurement accuracy throughout the meter's operational lifespan.

How often does the DN15 DN40 ultrasonic water meter require calibration?

Following international standards, these meters are designed to maintain accuracy for extended periods. Under normal operating conditions, calibration verification is recommended every 5-7 years, significantly less frequent than mechanical meters which typically require checking every 3-5 years.

Can these meters be installed in existing pipelines?

Yes, the DN15 DN40 ultrasonic water meters are designed for easy retrofitting into existing plumbing systems. They feature standard connection sizes that match common pipeline dimensions, minimizing installation time and modification requirements.

Are the meters affected by water quality issues?

The non-intrusive measurement method and brass construction make these meters highly resistant to common water quality issues. Unlike mechanical meters that can be affected by sediment or mineral deposits, the ultrasonic sensors remain accurate even in water with moderate levels of suspended particles.

What is the expected lifespan of these ultrasonic water meters?

With proper installation and under normal operating conditions, the Ultrasonic Water Meter DN15 DN40 has an expected service life of 10-12 years, outperforming many mechanical meters which typically last 6-8 years before requiring replacement.
