Frequently Asked Questions
What is the Ultrasonic Water Meter NW-3 Series used for?
The NW-3 Series is designed for accurate water flow measurement in municipal water systems, irrigation, industrial production, and automation control applications.
Does the water meter have moving parts?
No. The ultrasonic measurement principle eliminates rotating mechanical components, helping maintain long-term measurement accuracy.
Can the NW-3 Series be used for heat metering?
Yes. The meter supports dual PT1000 temperature sensors, enabling heat metering in HVAC, air conditioning, and refrigeration applications.
Is the water meter suitable for harsh environments?
Yes. The complete meter and its internal components are designed to meet IP68 protection standards, making it suitable for demanding industrial environments.
Practical Application Case: Improving Irrigation Water Management with the NW-3 Ultrasonic Water Meter
A municipal landscaping and agricultural irrigation project required more accurate water usage monitoring across multiple irrigation zones. The previous mechanical water meters experienced measurement deviations during long-term operation due to wear, making it difficult to accurately record water consumption and optimize irrigation schedules.
After upgrading to the NOIKE-AH NW-3 Series Ultrasonic Water Meter, the project benefited from its non-mechanical ultrasonic measurement technology, which eliminates moving parts and reduces wear-related accuracy loss. The meter’s IP68-rated sealed design also enabled stable operation in outdoor valve chambers and humid environments where conventional meters are more susceptible to water ingress.
The built-in quantitative control and time-based accumulation functions allowed the management team to schedule irrigation during off-peak hours and accurately record water usage for each irrigation period. The optional 4–20 mA, pulse, and communication outputs made it easier to integrate the water meter into the existing monitoring system, enabling centralized data collection and remote supervision.
