Fault name |
Solutions |
Converter no display |
1. Check whether the power supply is connected 2. Check whether the fuse is in good condition 3.Check whether the supply voltage meets the requirements 4. If the above three items are normal, please return the converter to the factory for maintenance |
Excitation alarm |
1. Excitation coil insulation decreased |
Empty pipe alarm |
1.Whether the measured fluid is full pipe 2.Whether the flowmeter is properly installed as required 3.The conductivity of the measured fluid is too low 4.The empty pipe threshold is setting too low |
Flow display when there is no flow |
1.The empty pipe threshold is setting too high 2.The empty pipe alarm permission is not opened 3.Electrode contamination leads to zero point offset (pipeline full pipe at this time) 4.Signal line insulation decreased (pipeline full pipe at this time) |
Flow measurement is inaccurate or fluctuates greatly |
1.Whether the fluid is full pipe 2.Whether the flowmeter is grounded as specified 3.Signal line insulation decreased 4.Whether the flowmeter is properly installed as required |
Flow Upper limit alarm |
1.The site flow rate is greater than the upper limit threshold of the flow , modify the upper limit threshold of the flow. |
Flow Lower limit alarm |
1.The site flow rate is lower than the lower limit threshold of the flow ,modify the lower limit threshold of the flow. |
No flow display when there is flow |
1.Whether the cut-off valve is open 2.Signal line ground 3.The flow is too low and the small signal resection setting is too high 4.The empty pipe threshold is setting too low |
