Zero drift issue with Emerson flowmeters
Thread Content
There is an electromagnetic flowmeter that frequently experiences zero drift – that is, it shows a flow rate reading even when it’s not in use during production. What could be the cause of this? How can the zero point be corrected? The model number is 1700L12AEPMZZZ. I would appreciate it if experts could provide detailed steps for correction. Thank you
Thank you for such a detailed explanation
This is my first time using this flow meter. Could you please tell me the menu steps for zero point adjustment? Thank you
First, check the air traffic control settings; secondly, it is possible to set a low-flow cutoff
In fact, the first thing to consider is the operating conditions and whether the medium is clean; it’s necessary to check whether there are stones or scale in the measurement tubes. In many cases, zero drift is caused by these factors, after which zero-setting attempts are made, and only then are a series of more complex inspections carried out. A 475 handheld programmer can be used for zeroing; the Chinese version is very simple, making it easy for beginners to use. If a 475 is not available, a computer with specialized software must be used, and if neither is available, one has to follow the instructions and press the buttons accordingly.
