Dear All, I'm using an IFM SBG446 4-20mA flow meter, I'm looking for way to measure the flow rate, after so many litres have passed I want to trigger the output. The flow info can be totalised or continuous. Min flow aprox 10 l/min, Max flow aprox. 100 l/min, My approach is to use analog input and measure flow in 10s intervals, calculate average flow in this interval, and calculate flow over a certain period, and compare with a set value(which I can increment/decrement on the display with up/down buttons). I know, my approach is somehow flawed, I would really appreciate your assistance. Regards AttachmentSBG446-00_EN-GB.PDF (311 Downloads) |

Here is a possible solution, which shows you the way with the block "Average Value". The measuring time is 10s, the number of measurements is also 10, so that every second takes a measurement. The scaling from 4 to 100 l / min have I taken from the data sheet. AttachmentAverage_value_0BA8.Standard.zip (438 Downloads) |
