4. Setup and Installation
Proper installation is crucial for accurate readings and safe operation.
- Unpacking: Carefully remove the flow meter from its packaging. Inspect for any signs of damage.
- Mounting Position: Install the meter in a horizontal or vertical position, ensuring the flow direction arrow on the meter body aligns with the fluid flow.
- Piping: Connect the meter using the 1-inch FNPT inlet/outlet. Use appropriate thread sealant to ensure leak-free connections. Avoid overtightening.
- Power: The meter is powered by two lithium batteries (included). Ensure they are properly installed.
- Initial Check: Before introducing fluid, ensure all connections are secure.
5. Operating Instructions
The meter features a simple two-button interface for operation and calibration.
Display Functions:
- The 6-digit LCD display shows the current flow total.
- Press the DISPLAY button to toggle between the resettable batch total and the non-resettable cumulative total.
- The display will show "TOTAL1" for the cumulative total and "FAC" (or similar indicator) for the batch total.
Resetting the Batch Total:
- Ensure the display is showing the batch total.
- Press and hold the DISPLAY button for approximately 3 seconds until the batch total resets to zero.
Calibration:
The meter is factory calibrated in gallons. Field calibration is possible to fine-tune accuracy for specific applications or fluids.
- Press the CALIBRATE button to enter calibration mode.
- Follow the on-screen prompts to adjust calibration parameters. Refer to the detailed calibration procedure in the full PDF manual for precise steps.
6. Maintenance
Regular maintenance ensures the longevity and accuracy of your flow meter.
Battery Replacement:
- The meter uses two field-replaceable lithium batteries with an approximate 5-year life.
- When the battery indicator appears or the display becomes dim, replace the batteries.
- The non-volatile memory will protect your cumulative total data during battery replacement.
- Refer to the full PDF manual for detailed instructions on accessing and replacing the batteries.
Cleaning:
- Clean the exterior of the meter with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
- If internal cleaning is required due to debris, consult the full PDF manual or contact GPI support.
Internal Parts:
The meter features simplified internal parts for ease of maintenance. If replacement of internal components is necessary, use only genuine GPI parts and follow the instructions in the detailed manual or seek professional assistance.
7. Troubleshooting
This section addresses common issues you might encounter.
| Problem | Possible Cause | Solution |
|---|---|---|
| No display or dim display | Low or dead batteries | Replace batteries. |
| Inaccurate readings | Incorrect calibration; Air in line; Meter used with incompatible fluid (e.g., water) | Perform field calibration; Bleed air from the system; Ensure only methanol is being measured. |
| No flow reading | No fluid flow; Meter installed backward; Obstruction in meter | Verify fluid flow; Check flow direction arrow and reinstall if necessary; Inspect for and remove obstructions. |
| Leakage at connections | Loose connections; Insufficient thread sealant | Tighten connections; Reapply thread sealant if necessary. |
If problems persist, refer to the comprehensive troubleshooting guide in the full PDF user manual or contact GPI customer support.
