What exactly does "wide range" mean? What is its value for large-volume projects?
A wide range refers to a water meter maintaining high accuracy across a wide flow range (typically R250/R400 and above).
Its value for large-volume projects lies in:
No missed readings at low flow rates (minor nighttime water usage, dripping)
No distortion at high flow rates (peak water usage, centralized water supply)
Reduced complaints and metering disputes, lowering operational risks
A unified model covering multiple operating conditions, simplifying procurement and inventory management.
How stable and long-term are ultrasonic water meters in large-scale, long-term use?
Ultrasonic water meters have no mechanical moving parts and therefore no wear issues, making them particularly suitable for long-term, large-scale installations.
Advantages include:
Strong resistance to water impurities, less prone to jamming
Long-term stable metering with minimal accuracy degradation
Typical design life of 10–15 years or more
Suitable for high-frequency meter readings and smart water management systems.
How to ensure product consistency and quality control during large-volume procurement?
For bulk projects, we typically offer:
Full-process calibration and factory testing (unit-by-unit or random sampling)
Compliance with international standards such as ISO 4064 / MID / OIML R49
Batch traceability (SN / production records / calibration data)
Support for third-party testing or project sampling requirements
Ensuring consistent performance and reliable data for every batch of water meters within the same project.
