Benefits and Advantages

Precision: The ability to capture and analyze the entire waveform allows for unparalleled accuracy in distance measurement, directly translating to more accurate airflow velocity readings.
Ease of Use: Since the system automatically calculates the distance between transducers, it eliminates the need for manual calibration or setup for distance measurements, making the sensor much easier to install and use, especially in challenging or inaccessible environments.
Versatility and Adaptability: The auto-ranging functionality makes the SONIC-1 sensor highly adaptable to various tunnel sizes and conditions without requiring hardware changes or manual recalibration, offering flexibility across different application scenarios.
Superior Performance: This feature ensures that SONIC-1 sensors can provide reliable and accurate measurements even in conditions where other sensors might struggle, such as in the presence of environmental noise, air turbulence, or when the installation alignment is not perfect.

Auto-Ranging

Signal Transmission and Reception

The SONIC-1 sensor system comprises two transducers, where one acts as a transmitter emitting ultrasonic pulses, and the other acts as a receiver. In auto-ranging mode, these roles can switch, allowing for dynamic adjustment and more accurate measurements.

Waveform Capture and Analysis

Upon emitting an ultrasonic pulse, the entire waveform of the returning signal is captured by the receiver. Unlike competitor models that may use a sliding window to capture only a portion of the waveform based on predefined expectations of its arrival, SONIC-1 captures the entire waveform from start to finish. This comprehensive capture is crucial for the next step.

Distance Calculation

By analyzing the captured waveform in its entirety, the system can accurately identify the first significant signal that represents the pulse's reflection from the opposite transducer. This process eliminates the errors that might arise from partial captures or environmental noise interference, leading to precise distance measurements between transducers.

Auto-ranging in the context of ultrasonic sensors, particularly those used for airflow measurement in tunnels, refers to the sensor's ability to automatically determine the distance between two transducer points without needing manual input or calibration from the user. This capability is essential for accurately measuring airflow velocity using the time-of-flight principle, where the time it takes for an ultrasonic pulse to travel from one transducer to another and back is used to calculate the air velocity.

Power Requirement: 24VDC @ 200mA (4.8W total system). / 120-220V AC

Default Network Mode: DHCP-enabled — device automatically requests an IP from your router.

1SD Card Support for Firmware Updates and Configuration:

Convenience: Allows for easy firmware updates by simply loading the new firmware files onto an SD card and inserting it into the device. This method simplifies the update process, especially in remote or hard-to-reach locations.
Bulk Configuration: By storing configuration files on an SD card, users can quickly deploy or update settings across multiple sensors without the need for individual manual configurations, significantly reducing setup time and effort.

2 TCP/IP and Modbus RTU for Communication and Integration:

Flexibility in Network Integration: With support for both TCP/IP (for Ethernet networks) and Modbus RTU (for serial communication), Sonic-1 sensors can easily integrate into various industrial control systems. This dual compatibility ensures that the sensors can communicate in environments that prefer either standard.
Remote Monitoring and Control: These communication protocols enable users to remotely monitor sensor readings and adjust configurations from a central control system or remotely via the internet, providing real-time access to sensor data and operational control.

3 Web Browser Interface for Easy Access and Configuration:

User-Friendly Configuration: The web browser interface allows users to access the sensor's settings through a simple, intuitive GUI. This makes it straightforward to configure the sensor, view real-time data, and perform diagnostics without specialized software.
Cross-Platform Compatibility: Being accessible via any standard web browser, this interface ensures that users can interact with the sensor system from any device, including PCs, tablets, and smartphones, offering flexibility in how and where users can manage their sensors.
