2.2 Transducer Installation (TM-1 Clamp-on Sensor)
The TM-1 transducers are clamp-on type, designed for non-invasive measurement.
- Vyberte bod měření: Choose a straight section of pipe, free from valves, pumps, or other obstructions that could disturb flow.
- Clean Pipe Surface: Ensure the outer surface of the pipe at the measurement point is clean and free of rust, paint, or debris.
- Apply Coupling Gel: Apply a generous amount of ultrasonic coupling gel to the contact surfaces of both transducers and the pipe. This is critical for signal transmission.
- Mount Transducers: Position the TM-1 transducers on the pipe according to the specified distance and orientation (refer to the detailed diagram in the full user manual for specific spacing based on pipe diameter). Use the provided steel belts to securely fasten the transducers to the pipe.
- Připojení signálních kabelů: Connect the 5m signal cables from the transducers to the corresponding ports on the TUF-2000B main unit. Ensure connections are tight and secure.

3. Návod k obsluze
Once installed, the TUF-2000B is ready for operation.
3.1 Zapnutí a počáteční konfigurace
Upon powering on, the device will perform a self-check. Use the keypad to navigate through the menu and input necessary parameters such as pipe diameter, material, and fluid type.

3.2 Měření průtoku
After configuration, the device will begin displaying real-time flow data on the LCD screen. The measurement principle relies on the time difference of ultrasonic signals transmitted through the fluid.
3.3 Data Recording and Retrieval
The TUF-2000B automatically records various data points. Access the menu to view historical data, including totalizer readings, power on/off events, and working status logs. If an optional SD card is installed, data can be stored and retrieved for further analysis.
3.4 Heat Measurement (Optional)
If a temperature transducer is connected, the flow meter can also calculate and display heat/energy consumption. Refer to the full user manual for specific instructions on connecting and configuring temperature sensors.
4. Údržba
Regular maintenance ensures the longevity and accuracy of your flow meter.
- Udržujte v čistotě: Wipe the main unit and transducers with a soft, dry cloth. Avoid abrasive cleaners or solvents.
- Zkontrolujte kabely: Periodically check signal cables for any signs of wear, damage, or loose connections.
- Transducer Contact: Ensure the coupling gel between the transducers and the pipe remains effective. Reapply if necessary to maintain good ultrasonic signal transmission.
- Ochrana životního prostředí: Ensure the main unit is protected from direct sunlight, excessive moisture, and extreme temperatures.
5. Řešení problémů
Pokud narazíte na problémy, podívejte se na následující běžné problémy a jejich řešení.
- Žádné/nepravidelné hodnoty:
- Check transducer placement and spacing.
- Ensure sufficient coupling gel is applied.
- Verify signal cable connections are secure.
- Confirm pipe parameters (diameter, material) are correctly entered in the device.
- Check for air bubbles or sediment in the pipe, which can interfere with ultrasonic signals.
- Problémy s napájením:
- Zkontrolujte, zda je napájecí kabel bezpečně připojen.
- Zkontrolujte zdroj napájení.
- Displej nefunguje:
- Ujistěte se, že je zařízení zapnuté.
- Contact technical support if the issue persists after checking power.
