What are the common causes and solutions for unstable measurements in LGF electromagnetic flowmeters?

LGF electromagnetic flowmeter unstable measurements commonly result from electrode contamination, pipeline vibration, electromagnetic interference, and improper installation. Electrode contamination is the most frequent cause, leading to signal fluctuation and measurement deviation, requiring regular electrode surface cleaning.

Solutions include: 1) Check electrode condition, remove dirt and deposits; 2) Ensure proper grounding to eliminate electromagnetic interference; 3) Verify upstream/downstream straight pipe requirements, typically upstream ≥5D, downstream ≥3D; 4) Adjust damping parameters, increasing damping improves display stability; 5) Confirm pipeline is completely filled with medium, avoiding bubble effects.

For Ecolor's LGF series, software diagnostic functions can check excitation current, electrode impedance and other parameters to assess equipment working status. If problems persist, recommend contacting technical support for in-depth analysis.
