Setup and Installation
Preparation
- Verify Gas Type, Flow Range, and Pipe Size: Before installation, confirm the specific gas type, desired flow range, and the correct pipe size for your application.
- Pipeline Cleanliness: Ensure the pipeline is clean and free from debris to prevent damage to the sensor and ensure accurate readings.
- Power Supply: Confirm that the power supply meets the required 24 V DC specification.
Installation
- Flow Direction: Install the device according to the flow direction indicated by the arrow on the housing.
- Sealing: Ensure proper sealing of all threaded connections to prevent gas leakage.
- Wiring: Connect power and signal lines according to the selected output method (e.g., RS485, 4-20mA analog output, or PNP).
Operation
Power On and Data Reading
- After powering on the device, the integrated LED display will show real-time flow data.
- To view cumulative flow, switch the display mode using the device buttons (ESC/▼, ▶/IN3, ENT/◀, ▲/OS3).
- Data can also be accessed via communication interfaces (RS485) or analog output (4-20mA, 0-5V).
Precautions
- Gas Compatibility: Ensure the gas medium is compatible with the sensor material (304 Stainless Steel).
- Environmental Limits: Do not exceed the specified operating pressure (≤1.5 MPa) and temperature (≤55°C) limits.
- Vibration and EMI: Avoid installation in environments with strong vibration or electromagnetic interference.
- Moisture: Prevent condensation or liquid from entering the sensor.
- Power Supply: Use a stable and regulated DC power supply (24V DC).
Storage and Maintenance
Storage
- Store the device in a clean and dry environment.
- Keep away from corrosive gases.
Maintenance
- Cleaning: Clean the surface of the device using a soft, dry cloth. Do not use solvents.
- Regular Inspection: Regularly inspect sealing and connections for any signs of leakage.
- Calibration: Periodic calibration is recommended to maintain measurement accuracy over time.
Troubleshooting
