Safety Information
WARNING: Failure to follow these safety instructions could result in serious injury or property damage.
- HAZARD WITH COVER REMOVED: Always turn off power before removing the cover of the sensor enclosure. This device is designed for explosionproof installations.
- For explosionproof installations, ensure conduit seals are located within 2 inches (50 mm) of the enclosure.
- This enclosure is FM approved as Explosionproof Class I Div. 1 Groups A, B, C, D; Dust Ignitionproof Class II, Div. 1 Groups E, F, G, Class III Div. 1.
- The sensor operates on 120/240V AC 20VA, or 13-30V DC, 1 Watt. T4. Ensure power supply matches these specifications.
- Installation must be performed according to drawing 420-0004-024-CD.
- The enclosure type is 4X, indicating protection against environmental elements.

Setup and Installation
Proper installation is critical for the accurate and safe operation of the VERIGAP Level Sensor. Refer to the specific installation drawing 420-0004-024-CD for detailed instructions relevant to your application.
Mounting
The sensor should be mounted securely in the desired location, ensuring the probe is correctly positioned for level detection. Consider the process conditions such as pressure and temperature when selecting the mounting point.
Electrical Connections
Connect the power supply to the "POWER IN" port as indicated on the sensor housing. Ensure the power source is within the specified voltage range (120/240V AC or 13-30V DC). All wiring should comply with local electrical codes and the explosion-proof requirements outlined in the safety section.

Operation
The AMETEK VERIGAP Level Sensor is designed for continuous and reliable level measurement. Once properly installed and powered, the sensor will begin detecting the liquid level based on its calibration. The output signal will correspond to the measured level, which can then be integrated into your control system.
This sensor is calibrated for 1000 PSI, making it suitable for high-pressure applications. Ensure the process pressure does not exceed the maximum working pressure (MWP) of 6880 kPa or 1000 psi up to 121°C (250°F).
Figure 5: Close-up of the sensor probe's identification label, indicating the Maximum Working Pressure (MWP) of 6880 kPa or 1000 psi up to 121°C or 250°F, and a serial number (e.g., AGQ-002417).
Maintenance
The VERIGAP Level Sensor is built for durability and requires minimal routine maintenance. However, periodic checks are recommended to ensure optimal performance and longevity.
- Cleaning: Periodically inspect the sensor probe for buildup or fouling, which may affect accuracy. Clean the probe gently using appropriate methods for the process media.
- Connections: Verify that all electrical connections are secure and free from corrosion.
- Enclosure Integrity: Inspect the enclosure for any signs of damage or compromise, especially in harsh environments, to maintain its Type 4X rating and explosion-proof integrity.
Troubleshooting
This section provides general guidance for common issues. For complex problems, contact AMETEK technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| No output/Incorrect reading | No power, incorrect wiring, sensor fouling, incorrect calibration. | Check power supply and connections. Inspect and clean sensor probe. Verify calibration settings. |
| Intermittent readings | Loose connections, electrical interference, process instability. | Secure all wiring. Check for sources of electrical noise. Evaluate process conditions. |
| Physical damage to enclosure | Impact, chemical exposure. | Replace damaged components or the entire unit to maintain safety ratings. |
