A customer wanted to have a flow measurement done at a campsite.
We set up the equipment for Easter, on a pipe from a pumping station near the campsite. It is interesting to follow the development on the graphs, where especially on Sundays from 7 am. 12 and until midnight there is a steadily increasing level and speed, which is probably due to it being the day of return for many of the guests of the campsite. The example illustrates very well how exactly the correlation principle works in practice.
