Trust me it can dear m.shoaib khatana, because you end upadding a tiny bit too small value thousands of times to an ever increasing total. It's yourcall at the end of the day what you want to test or try though. If you want to be really precise,I forget to mention the best way to do totalising which is: Use a Digital Output of your Flowmeter (it should have one, most do anyhow), connect it to a free DI, configure the Flowmeter to give you a pulse perx amount and then simply add up the pulses (doing Totalsbased on AI will never be 100% accurate even if Siemens provides you with a block for this purpose). The only thing to look out for is to make sure that the DI pulses are not missed (i.e. they are long enough andand don't come faster that the scan of the logic that evaluates them). I hope this helps |
