3.2 Transducer Installation
The TM-1 transducers are designed for pipes with diameters ranging from DN50mm to DN700mm. Proper installation of the transducers on the pipe is critical for accurate measurements. Ensure the pipe surface is clean and free of rust or paint. Apply coupling gel generously between the transducers and the pipe surface to ensure good acoustic contact. Mount the transducers according to the specified distance and configuration (Z-method or V-method) as detailed in the full technical manual, ensuring they are securely clamped.
4. Operating Instructions
4.1 Powering On and Basic Display
Once wired correctly and powered on (24V DC), the module's LCD display will illuminate. The display typically shows real-time flow rate, totalizer values, and other operational parameters. Use the MENU, UP, DOWN, and ENT buttons on the front panel to navigate through the menus and configure settings.

4.2 Configuration and Calibration
Access the configuration menu by pressing the MENU button. From here, you can set parameters such as pipe diameter, pipe material, liquid type, and transducer spacing. Initial calibration may be required to optimize accuracy for specific applications. Refer to the detailed technical manual for step-by-step calibration procedures.
4.3 Data Output and Communication
The module provides several output options:
- 4-20mA Analog Output: One channel available for transmitting flow or heat data to external devices like PLCs or data loggers.
- OCT Output: Two channels for flow or heat switching applications.
- RS-232/RS-485 Output: Isolated communication interfaces for connecting to computers or other network devices. Supports MODBUS, METER-BUS, Fuji extended, and general water meter protocols.
Ensure external devices are configured to match the module's communication settings (e.g., baud rate, parity, data bits).

- Environmental Conditions: Operate the module within its specified environmental limits (temperature, humidity) to prevent damage.
7. Troubleshooting
This section provides basic troubleshooting steps for common issues. For more complex problems, consult the full technical manual or contact customer support.
- No Display/Power:
- Check the 24V DC power supply connection and ensure it is providing the correct voltage.
- Verify that the power cables are securely connected to the module.
- Inaccurate Flow Readings:
- Ensure transducers are correctly installed and spaced according to the pipe diameter and material.
- Verify that sufficient coupling gel is applied between transducers and the pipe.
- Check for air bubbles or sediment in the pipe section where transducers are mounted.
- Confirm that the pipe parameters (diameter, material) are correctly configured in the module's settings.
- No Signal Output (4-20mA, OCT, RS-485):
- Check the wiring for the respective output.
- Verify that the output settings are enabled and correctly configured in the module's menu.
- Ensure the receiving device (PLC, data logger) is correctly configured to receive the signal.
- Communication Errors:
- Verify RS-485 wiring polarity (A to A, B to B).
- Check communication parameters (baud rate, data bits, parity) on both the module and the connected device.
- Ensure proper termination resistors are used if required for the RS-485 network.
