Possible causes: The wiring might be incorrect or the cable could be damaged. The Modbus communication lines (D+ and D−) may be reversed. If you’re using Modbus TCP, the sensor might be connected directly to a PC instead of through a network switch or hub. The...

Possible causes: The output signal wiring might be connected incorrectly. A fuse or component in the measurement system may be blown. The analog output scaling (e.g., 4–20 mA) might not be correctly configured. The installed output board might not match your system’s...

Possible causes: The sensor may be incorrectly installed — for example, not centered or installed at the wrong depth. The wrong gas type, flow units, or reference conditions may be selected in the settings. The inner pipe diameter might be entered incorrectly in the...

Possible causes: The air or gas might be contaminated with moisture, oil, or particles. Turbulent flow caused by nearby elbows, valves, or other obstructions may be affecting readings. The sensor could be loose or not inserted to the correct depth. Solutions: Inspect...

Possible causes: A zero-flow calibration has not been performed or was done incorrectly. High humidity or oil residue may cause thermal sensors to register false readings. Nearby machinery or vibrations might create noise signals that are interpreted as flow....
