Why does my flow meter not read accurately or show incorrect values?

Q: Why does my flow meter not read accurately or show incorrect values?

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 software. The sensor technology may not be suitable for the current application (e.g., thermal mass sensors in very humid environments). There may not be enough straight pipe before or after the sensor, causing turbulent flow. Solutions: Verify the sensor is properly centered in the pipe and installed at the recommended depth and orientation. Check the gas type, measurement units, and reference pressure/temperature conditions in the S4C-FS software. Enter the correct inner pipe diameter to ensure proper flow calculation. Make sure the sensor technology is appropriate for the gas conditions (e.g., avoid thermal mass sensors where liquid water may be present). Install the sensor with adequate straight pipe lengths before and after, as specified in the manual.
