Setup
1. Package Contents
- 2 x Mopeka Pro Check Universal Sensors
- 2 x Mopeka Tank Halos
- 6 x Aluminum Spacers (3 per sensor)
- 2 x Acoustic Grease Packs (1 per sensor)
2. Sensor Installation
- Prepare the Tank: Ensure the bottom surface of your tank is clean and free from debris.
- Apply Acoustic Grease: Apply a small amount of the provided acoustic grease to the center of the sensor's top surface. This grease is crucial for accurate readings.
- Attach the Sensor: Position the Mopeka Pro Check Universal Sensor centrally on the underside of the tank. The sensor attaches securely using powerful magnets. For tanks with a recessed bottom, use the included aluminum spacers to ensure a flat contact surface between the sensor and the tank.
- Install Tank Halo (Optional but Recommended): Place the Mopeka Tank Halo around the base of the tank. This protective ring helps secure the sensor and provides additional stability, especially for RVs on uneven terrain.

Maintenance
1. Battery Replacement

2. Acoustic Grease Reapplication
The acoustic grease is vital for accurate ultrasonic readings. If you notice inconsistent or inaccurate readings, or if the sensor has been removed and reattached, reapply a fresh layer of acoustic grease to the sensor's contact surface.
3. Cleaning
Wipe the sensor and Tank Halo with a damp cloth as needed to remove dirt or grime. Avoid using harsh chemicals or abrasive cleaners.
Troubleshooting
- No Reading or Inaccurate Reading:
- Ensure the sensor is firmly attached to the tank bottom with good contact.
- Verify that acoustic grease is properly applied between the sensor and the tank.
- Check the battery level of the sensor in the app. Replace if low.
- Confirm the correct liquid commodity is selected in the app for the tank.
- Note: While versatile, some users report less consistent readings with water tanks compared to propane. Ensure proper installation and grease application for water tanks.
- Signal Issues / Connectivity Problems:
- Ensure Bluetooth is active on your mobile device.
- Bring your mobile device closer to the sensor.
- Restart the Mopeka Tank Check app.
- If using a Mopeka Wifi Bridge (sold separately), ensure it is properly configured and within range.
- Firmware Updates:
- The Mopeka Pro Check Universal Sensor supports firmware updates via the app. Check the app's settings periodically for available updates to ensure optimal performance and access to new features.
