The vortex flowmeter suddenly has no current output.<\/strong><br \/>\n[Fault check]: Check if the power supply is normal. Use handheld operator to test the loop, set the range of 0%, 25%, 50%, and 100% in the J10 parameter, and there is no current output. It is judged that the amplifier is faulty.<br \/>\n[Troubleshooting]: After replacing the amplifier and resetting the parameters (key parameters such as K factor, size, range, etc.), the vortex flowmeter returns to normal.<\/p>\n<p><strong>2. The process has no flow, while the vortex flowmeter still shows flow.<\/strong><br \/>\n[Fault check]: Firstly, check the setting of small signal removal, and finally, it is found that the parameter setting is wrong, and the size of the flowmeter is set incorrectly.<br \/>\n[Troubleshooting]: After modifying the meter size, the flowmeter displays normally.
