Summary of reasons for inaccurate electromagnetic flowmeter measurement

Eliminate the quality problems of the flowmeter itself, and the side of the electromagnetic flowmeter is not allowed. Summary 1. There are air bubbles in the liquid; 2. The inaccurate measurement is caused by a partly full pipe; 3. The electrode corrosion of the electromagnetic flowmeter leads to inaccurate measurement; 4. The conductivity of the measured medium Too low leads to inaccurate measurement; 5. Inaccurate measurement due to electrode fouling and electrode short circuit of electromagnetic flowmeter; 6. Inaccurate measurement due to deformation of electromagnetic flowmeter lining; 7. Inaccurate measurement caused by external strong electric field; 8. Electromagnetic flowmeter The grounding effect is not good; 9. The straight pipe section at the installation position of the electromagnetic flowmeter does not meet the requirements.
