What to do if the velocity exceeds limits on GE Measuring Instruments?
If the measured velocity exceeds the programmed velocity limit, ensure that the actual flow rate is within the programmed limits. You may need to check the value programmed in the Program > Advanced > Error Limits > Velocity Low/High menu. The error may be caused by improper programming, poor flow conditions, and/or excessive flow turbulence.
What to do if sound speed exceeds limit on GE Measuring Instruments?
If the measured sound speed exceeds the programmed sound speed limit, correct any programming errors. Also, check the value programmed in the Program > Advanced > Error Limits > SNSD +- Limit menu. The error may result from incorrect programming, poor flow conditions, and/or poor transducer orientation.
What to do if the ultrasonic signal strength is poor on GE Measuring Instruments?
If the SNR is less that the value of Signal Low Limit or the signal cannot be found when the flow is started, the Low Signal error is displayed. Also, check the programmed value in the Program > Advanced > Error Limits> Signal Low Limit menu. Poor signal strength may be caused by a defective cable, a flowcell problem, a defective transducer or a problem in the electronics console. A signal that exceeds the programmed limits is probably caused by the entry of an improper value in the menu Program > Advanced > Error Limits > Signal Low limits.
Why does signal amplitude exceed limits on GE AquaTrans AT600?
The signal amplitude may exceed the limits programmed in the Program > Advanced > Error Limits > Amp Disc Min/Max menu because solid or liquid particulates may be present in the flowcell. Also, poor coupling for the clamp-on transducers can cause this problem.
