Key Features
Ultrasonic Water Meter
The Ultrasonic Water Meter is an advanced flow measurement device that utilizes ultrasonic technology to calculate water flow velocity by measuring the time difference of ultrasonic wave propagation between downstream and upstream directions. This non-invasive method provides highly accurate and reliable water consumption data for a wide range of applications, from residential to industrial use.
Structure of the Ultrasonic Water Meter
The meter is engineered with a robust and intelligent structure. Its core components work in harmony to deliver precise and stable flow measurement under various conditions.
- Meter Body
- Constructed from corrosion-resistant materials to ensure smooth water flow and long-term durability, clearly marked with all necessary specifications and parameters.
- Ultrasonic Transducer
- Converts electrical energy into ultrasonic energy and vice versa. At least two transducers are used for transmitting and receiving signals to enable accurate flow velocity calculation.
- Signal Processing Unit
- Processes weak ultrasonic signals, calculates the time difference to obtain flow velocity, and includes data validation, error correction, and a powerful microprocessor.
- Data Storage & Display Unit
- Stores historical flow data securely. A high-definition LCD displays real-time and historical information, featuring reliable power-off protection.
Key Performance Features
High Accuracy and Wide Turndown Ratio
This ultrasonic flow meter provides precise measurement, completely unaffected by impurities or vibration in the pipeline, achieving an accuracy of Class 1 or Class 2. Its wide turndown ratio allows it to adapt seamlessly to both high and low flow rates, preventing under-registration and overload.
High Reliability
With no moving mechanical parts, there is zero wear, ensuring long-term stability and a long operational lifespan. The durable housing is resistant to harsh environmental conditions.
Intelligence & Communication
Supports multiple communication protocols, enabling remote monitoring, management, and fault diagnosis for efficient water utility management.
Low Power Consumption
Battery-powered models are designed for ultra-low power consumption, ensuring a long battery life of 6+1 years with a built-in lithium battery.
Advanced Measurement and Diagnostic Technology
The meter employs dual-channel measurement for enhanced accuracy and stability. Its redundant design ensures normal metering continues even if one channel is blocked or malfunctions.
Comprehensive self-diagnostic functions provide immediate alerts for issues such as flow sensor faults, temperature sensor open/short circuits, over-range measurement, and low battery, ensuring reliable operation.
