Issues with GE AT600 ultrasonic flowmeter
Thread Content
There is a phenomenon at present: the flow meter uses a 4-wire system, and when the signal line becomes open-circuited and then reconnected, the current in the signal line of the flow meter remains at 3.58 mA. The DCS displays incorrect values; it is necessary to power off the flow meter and turn it back on for everything to return to normal. Is there a Chinese version of the manual? I want to check if there are any settings that need to be adjusted
What is its signal quality? With low signal quality, anything can happen. Also, how long have you been using this (is it new or has it been in use for a long time)? What’s the condition of the coupling agent? ……
The newly installed ones all work well now, but once the signal cable is disconnected and then reconnected, the faulty value remains; it’s necessary to power it on again

After being powered on again, the flow meter should perform a self-check to determine if there are any alarm codes.
I’ve never used it; there might be a setting for resetting signal fault alarms, but I still think that turning off the power before reconnecting the wires is a good habit, unless it’s a strict requirement.
Hehehe, congratulations! You, the ultrasonic crazy lady – all those crazy tricks are meant to amuse you. If you tell the person who designed this watch about the problems, he might not even be able to explain why they exist! Hehe, why? Because, if he knew, damn it, he wouldn’t design the instrument in such a terrible way, just to annoy people by forcing them to post complaints about it..... :lol So, no matter how big a company is, there are still only a few people responsible for designing the instruments. If those people come up with flawed design concepts and incomplete testing plans, then... well, you end up having to pay extra to deal with all this hassle. {:2_45:}
