E+H radar and FOXBORO pH meter
Thread Content
1. For the E+H radar level gauge in an atmospheric-pressure storage tank, there is no fluid inside the tank anymore, but the level is still indicated as 9%. The gauge’s display shows error E641; trying to adjust the display to show 0.7% did not resolve the issue, and the error E641 persisted even after cleaning the radar antenna. What should be done? Also, are there any other treatment methods if suppression is not used? 2. I have a FOXBORO pH meter; I’m not sure which technician has its menu, and I’m not very proficient at using it. Could someone provide instructions? Thank you! :)
The 641 alarm is an header alarm; it’s sufficient to reduce the suppression to near zero. . There’s no need to do it. . . .
The key issue is that E641 is still being reported after the suppression process is completed; it should be close to zero by then.:
What is the model of the pH meter in FOXBORO? The one from that series?
I don’t quite understand this thing, but I think it’s necessary to figure out what code E641 is and what it specifically means. If we know it, it should be easier to handle, right?
641 is a loss of wave alarm; everything will return to normal once the level rises. If you really want to eliminate this alarm, simply set the height of the empty tank to be a bit higher than the actual height of the tank. . The radar detection of the tank bottom also shows a value of 0.x%
Well, that makes sense. Thank you so much!
