2. Setup and Installation
Proper installation is crucial for accurate and reliable operation of the Ultrasonic Flow Meter. This meter is designed for clamp-on installation on DN50 pipes.
2.1 Environmental Considerations
- Temperature Range: Ensure the operating environment is within -25°C to 55°C.
- Protection Level: The device is IP68 rated, making it suitable for outdoor and harsh environments, providing protection against dust and prolonged immersion in water.
- Working Pressure: The system pressure should not exceed 1.6 MPa.
2.2 Physical Installation
- Pipe Selection: Identify a suitable section of DN50 pipe where the flow meter will be installed. Ensure the pipe section is straight and free from obstructions for optimal flow measurement.
- Mounting Transducers: Securely clamp the ultrasonic transducers onto the exterior of the pipe according to the specific instructions provided in the detailed installation guide (refer to the included manual for precise spacing and orientation).
- Cable Connection: Connect the transducer cables to the main meter unit. Ensure all connections are tight and properly sealed to maintain the IP68 rating.

3. Operation
The GOYOJO Ultrasonic Flow Meter features an intuitive interface for easy monitoring and data access.
3.1 Display and Controls
The meter is equipped with an LCD display and two capacitive touch keys for navigation and control. The display provides real-time data:
- Cumulative Flow: A 9-digit display shows the total accumulated flow.
- Instantaneous Flow: A 6-digit display indicates the current flow rate.
- Signal Strength: An indicator for the quality of the ultrasonic signal, essential for accurate readings.
The capacitive touch keys allow users to cycle through display modes, access settings, and perform basic configurations. Refer to the detailed user manual for specific key functions and menu navigation.

3.2 Communication and Integration
The flow meter supports various communication protocols for integration into smart water management systems:
- Standard Interface: RS485.
- Optional Interfaces: LORA, NB-IOT, WIFI, USART.
- Protocols: Compatible with MODBUS, MBUS, and other industry-standard protocols.
These options enable remote monitoring, data logging, and integration with existing control systems.
4. Maintenance
The GOYOJO Ultrasonic Flow Meter is designed for low maintenance due to its robust construction and IP68 rating. Regular checks can help ensure continued accuracy and longevity.
- Visual Inspection: Periodically inspect the meter and transducer cables for any signs of physical damage, corrosion, or loose connections.
- Cleaning: If installed in an exposed environment, gently clean the exterior of the meter and transducers to remove dirt or debris that might accumulate. Avoid using abrasive cleaners.
- Transducer Coupling: Ensure the transducers remain securely clamped to the pipe and that the coupling gel (if used during installation) is intact. Poor coupling can affect measurement accuracy.
- Software/Firmware Updates: Check with the manufacturer for any available software or firmware updates that may improve performance or add features.
The ultrasonic measurement principle means the meter is generally unaffected by water quality, reducing the need for internal cleaning or recalibration due to sediment buildup.
5. Troubleshooting
If you encounter issues with your GOYOJO Ultrasonic Flow Meter, consider the following common troubleshooting steps:
- No Display/Power:
- Verify power supply connections.
- Check for any visible damage to cables or the unit.
- Inaccurate Readings/No Flow Detected:
- Ensure transducers are correctly positioned and securely clamped on the pipe.
- Check the signal strength indicator on the display. A weak signal may indicate poor transducer coupling or incorrect placement.
- Confirm the pipe material and diameter settings in the meter's configuration match the actual pipe.
- Verify that there is actual flow in the pipe.
- Communication Issues:
- Check all communication cable connections (RS485, etc.).
- Verify communication settings (baud rate, parity, address) on both the meter and the connected system.
- Ensure the correct communication protocol (MODBUS, MBUS) is selected.
For persistent issues, consult the comprehensive user manual or contact GOYOJO technical support.
