4. Setup and Installation
Proper installation is crucial for the accurate and reliable operation of the cooling meter. Refer to the detailed installation instructions provided with the product packaging for specific diagrams and steps.
4.1 Pre-Installation Checks
- Verify that the meter's specifications (flow rate, pressure, temperature) match the system requirements.
- Ensure the installation site is clean, dry, and free from excessive vibrations.
- Confirm that all necessary tools and fittings (e.g., G5/4B connections, seals) are available.
4.2 Mechanical Installation
- Install the meter in the return pipe of the cooling circuit, ensuring the flow direction arrow on the meter matches the system flow.
- Maintain adequate straight pipe sections upstream and downstream of the meter as recommended by the manufacturer to ensure accurate flow measurement.
- Use appropriate gaskets and tighten connections to prevent leaks. The meter has a length of 260mm and G5/4B connections.
- Ensure the meter is not subjected to mechanical stress from the piping.
4.3 Electrical Connection (M-Bus)
- Connect the M-Bus communication cable to the designated terminals on the meter.
- Ensure proper polarity and secure connections.
- Integrate the M-Bus connection with your building management or data acquisition system according to the system's specifications.
