3. Setup and Installation
Proper installation is crucial for the accurate and reliable operation of the level transmitter. Follow these steps carefully:
- Safety First: Ensure that the power supply is disconnected before beginning any installation or wiring procedures.
- Mounting: The transmitter should be suspended vertically into the liquid. Ensure the sensor head is fully submerged and positioned away from strong currents or turbulence that could affect readings. The cable should be secured to prevent strain on the sensor.
- Wiring: Connect the transmitter to a 24VDC power supply. The output is a 4-20mA current signal. Refer to the wiring diagram below for correct connections.
- Red wire: Positive (+) for power supply.
- Black wire: Negative (-) for power supply and signal return.
- Cable Management: Ensure the cable is routed safely, avoiding sharp edges or areas where it could be damaged. The cable is designed for submersion and durability.
- Power On: Once all connections are secure, apply 24VDC power to the transmitter.

4. Operating Instructions
The Garosa Level Transmitter operates continuously once powered, providing real-time liquid level data via its 4-20mA output.
- Continuous Monitoring: The sensor will continuously measure the liquid level and transmit the corresponding 4-20mA signal to your control system or display unit.
- Signal Interpretation: The 4mA output typically corresponds to the minimum measured level (e.g., 0 meters), and 20mA corresponds to the maximum measured level (e.g., 6 meters). Your receiving device should be calibrated to interpret this range correctly.
- Environmental Considerations: Ensure the measured liquid remains within the specified temperature range (-20°C to 75°C) and is non-corrosive to stainless steel to maintain sensor integrity and accuracy.

5. Maintenance
The Garosa Level Transmitter is designed for low maintenance. Regular checks can help ensure its longevity and accuracy.
- Periodic Inspection: Periodically inspect the sensor head and cable for any signs of damage, corrosion, or accumulation of debris.
- Cleaning: If debris or buildup is observed on the sensor head, gently clean it using a soft cloth and clean water. Avoid using abrasive materials or harsh chemicals that could damage the stainless steel housing or sensing elements.
- Cable Integrity: Check the cable for any cuts, abrasions, or kinks. Ensure the cable glands are tight to maintain the IP68 rating.
- Connection Check: Verify that all electrical connections remain secure and free from corrosion.
6. Troubleshooting
If you encounter issues with your level transmitter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No 4-20mA output | No power supply; incorrect wiring; damaged cable. | Check 24VDC power supply; verify wiring connections; inspect cable for damage. |
| Inaccurate readings | Sensor head obstructed; turbulence in liquid; incorrect calibration of receiving device. | Clean sensor head; reposition sensor away from turbulence; recalibrate receiving device. |
| Intermittent readings | Loose electrical connections; cable damage. | Check and secure all connections; inspect cable for damage. |
| Sensor not responding | Complete sensor failure; severe power issue. | Verify power supply is stable; if problem persists, contact customer support. |
