[kasche]

hello,

i need some help to integrate a flowmeter in my messurementprogram!

the flow meter opens for every ltr. a potential free contact.

i could count with my program the hole value from programstart to programmend but i need to display the flowrate

in m³/h,aktualizing every 3 minutes.

is there someone with a idea?

Hi kasche,

seema you're from Germany

What about this to display flowrate:

You have to put this in a loop iterating once every 3mins and provide the count of the last 3mins to get the flow...

Hi GerdW,

is this counter you called "Counter of last 3 mins", a hardwarecounter?

I use a digital input-modul and get for every ltr one pulse.

The problem is to get a continuous pulse-average of 3 minutes, so that i able to calculate the m³/h.
