How to troubleshoot error codes on LGF electromagnetic flowmeters?

LGF electromagnetic flowmeters may display various error codes during operation, with proper troubleshooting essential for maintaining measurement accuracy. Understanding these codes helps operators quickly identify and resolve issues.

• E01 - Excitation coil fault: Check coil connections and measure resistance (20-100Ω normal range)
• E02 - Empty pipe detection: Verify pipe is completely filled with conductive fluid
• E03 - Signal amplitude low: Check fluid conductivity and electrode condition
• E04 - Output current fault: Inspect 4-20mA output circuit and load resistance

For industrial flow measurement applications, systematic diagnosis prevents costly downtime. Always consult the LGF series manual and contact Ecolor Technology support for complex issues requiring specialized expertise.
