Hello I am trying to prepare a program which can calculate on line volume flow per second using only pulses from flowmeter - using s7-1200 I was looking in a forum but can't find solution, topic like this -https://support.industry.siemens.com/tf//ww/en/posts/flowrate-calculation-from-pulses/218456/?page=0&pageSize=10 is not working for me ...I do not know why. In attachemnt there is logic prepared according to pdf on the bottom of the above page but as I said is not working for me. My example is 1 pulse is for example 1 liter I would like to count volume flow per second - liters/seconds Kind regards Leszek [snip] - link to download tia portal 15 project (zip) Attachmentvolume flow.zip (348 Downloads) |

hello 0_Einstein - I will try your method with hardware when I get it, in the meanwhile I will try to do the simulation with only tia portal. In attachemnt I have sent screen of my "logic".It is not complete becouse I do not understand what should be - old and - new value. I have only current value from counter. |
