The dispaly of electromagnetic flowmeter is unstable, and customers judge the flow value is high based on past value
Upon receiving feedback from the customer, the Anretang technical team immediately went to the customer site to examine and analyze the faults:
1. The electromagnetic flowmeter calibre is DN100, consistent with the calibre of the pipe measured in the field
2. Check the sensor coefficients of the electromagnetic flowmeter,According to the traceable source, sensor coefficients 1.7534 and the coefficient is consistent with the number calibrated by factory before shippment
3. The flow control valve is installed at the entrance of the electromagnetic flowmeter and the length of the front and rear straight pipe sections does not meet the installation requirements, resulting in a high measurement value
Modify the small signal cut point and make the value same as the setting number before shipping.
After modifying the small signal cut point,when no traffic running in the pipe the number of converters is normal at 0m/s
