Ultrasonic Water Meter Manufacturers

Performance characteristics of ultrasonic water meter

In the field of smart water services, ultrasonic water meters have gradually emerged and become a popular choice in the market with their unique measurement principles and technical advantages. As one of the core products of Ningbo Jingcheng Technology Co., Ltd., our ultrasonic water meters not only meet the international standards ISO 4064 B, C, and D, but also show excellent performance and advantages in many aspects to meet the diverse needs of modern water management.
Ultrasonic water meters use advanced ultrasonic measurement technology to calculate flow by accurately measuring the propagation time difference of ultrasonic waves in the fluid. This non-contact measurement method effectively avoids the measurement errors caused by wear, water quality changes and other factors in traditional mechanical water meters. Therefore, ultrasonic water meters perform well in measurement accuracy and stability. Its high-precision measurement capability can accurately reflect the actual water consumption of users, providing a reliable basis for the management and billing of water resources.
In terms of adaptability, ultrasonic water meters have an extremely wide range ratio, which can usually reach 100:1 or even higher. This feature enables ultrasonic water meters to maintain high-precision measurement performance in environments with large flow changes. Whether in residential or industrial areas, ultrasonic water meters can effectively respond to different water needs, avoid the trouble of frequent water meter replacement, and greatly improve the user's convenience.
The non-contact measurement principle of ultrasonic water meters also means that there is almost no problem of mechanical wear. Compared with traditional water meters, the service life of ultrasonic water meters is significantly extended and the maintenance cost is greatly reduced. This advantage not only saves users the cost of replacing water meters, but also reduces the inconvenience of water outages caused by water meter failures, and improves users' water experience.

How Ultrasonic Water Meters Work

Principle of Ultrasonic Flow Measurement
Ultrasonic meters measure flow by using sound waves to determine water velocity. Two transducers send and receive signals through the flowing water. The difference in signal travel time between upstream and downstream paths determines flow speed and total volume.

At NINGBO JINGCHENG TECHNOLOGY CO., LTD., precision-engineered transducers and digital signal processors ensure stable readings across varying flow and temperature conditions, delivering accurate results without mechanical wear.

Transit Time Method
The transit time method measures the difference in time it takes for ultrasonic pulses to travel with and against the flow. This time difference (Δt) is proportional to flow velocity.

Jingcheng uses the transit time method in residential and industrial models for high sensitivity at low flow rates, ensuring precision in both small and large-scale applications.

Doppler Effect Method
For water with suspended particles or air bubbles, Jingcheng applies the Doppler method, where reflected sound waves from moving particles indicate flow velocity. This design suits irrigation, wastewater, and industrial processes.

Signal Processing and Data Conversion
Jingcheng’s low-power microcontroller and ASIC perform signal sampling and compensation, calculating instantaneous flow, cumulative volume, and diagnostics. Communication interfaces include Modbus, M-Bus, and wireless RF, compatible with AMR/AMI smart networks.

Measurement Process Illustration
The measurement principle involves two transducers (A and B) on the pipe wall transmitting signals in both directions. The time difference between upstream and downstream travel determines flow velocity, which the electronic unit processes to display readings.
