5. Setup

Proper installation is crucial for accurate measurement and safe operation. Follow these steps for setting up your Wiltec Diesel or Fuel Meter:

1. Unpack and Inspect: Carefully remove the meter from its packaging and inspect for any visible damage.
2. Choose Location: Select a stable and secure location for mounting the meter, ensuring it is easily accessible for reading and maintenance.
3. Connect Hoses: The meter is equipped with 1-inch (30.93 mm) female threaded connections. Connect your fuel hoses to the inlet and outlet ports. Ensure the flow direction arrow on the meter body aligns with the direction of fluid flow.
4. Seal Connections: Use appropriate thread sealant (e.g., PTFE tape or liquid sealant compatible with fuels) on all threaded connections to prevent leaks. Tighten connections firmly but do not overtighten.
5. System Integration: Integrate the meter into your existing fuel transfer system, ensuring it is positioned correctly between the pump and the dispensing nozzle or receiving tank.
6. Initial Check: Before full operation, perform a visual check for any leaks and ensure all components are securely fastened.

6. Operating Instructions

The Wiltec Diesel or Fuel Meter is designed for straightforward operation. Follow these steps to accurately measure fluid volumes:

1. Power On (if applicable): If your system includes a pump, ensure it is powered on and ready for operation. The meter itself is mechanical and does not require external power.
2. Reset Batch Volume: Before starting a new measurement, locate the reset knob (typically on the side of the meter). Turn this knob until the 4-digit subtotal display reads "0000". This resets the current batch volume. The 8-digit total volume is cumulative and cannot be reset.
3. Begin Fluid Transfer: Start the flow of diesel, fuel oil, or rapeseed oil through the meter. The display will begin to register the volume of fluid passing through.
4. Monitor Display: Observe the 4-digit subtotal display for the current volume being dispensed. The 8-digit total display will continuously accumulate the total volume measured over the meter's lifetime.
5. End Fluid Transfer: Once the desired volume has been dispensed, stop the fluid flow. Record the reading from the 4-digit subtotal display if needed.
6. Flow Rate: Ensure the fluid flow rate remains within the specified range of 20-120 l/min for optimal accuracy.

7. Maintenance

Regular maintenance ensures the longevity and accuracy of your fuel meter:

• Inspection: Periodically inspect the meter, hoses, and all connections for signs of wear, damage, or leaks. Address any issues promptly.
• Cleaning: Keep the meter's exterior and display window clean using a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the materials.
• Environmental Protection: While robust, avoid exposing the meter to extreme temperatures, direct prolonged sunlight, or harsh weather conditions when not in use.
• Calibration Check: If precise measurements are critical, periodically check the meter's accuracy against a known volume. If significant discrepancies are observed, recalibration may be necessary. Refer to manufacturer guidelines or a qualified technician for calibration procedures.
