counting pulse flowmeter

HELLO
I have' a flow meter that continuously passes the milk and milk passage of which is shown on the display. So far, I have no problem, but I want to calculate the amount of flow passing through a period in the past and show on display
Is it possible the flow versus time graph on the display event? And then using the above graph in a specified time interval to calculate the amount of milk has been passed?
my pls is s7 siemens

See if the flow meter has an inbuilt totaliser, if not create one. Use a counter or simple x = x+1 every time you receive a pulse from the flow meter.

Points to consider...

• Figure out when it is product, so you only count product
• Figure out when you want to reset your totaliser

As for these questions you will need to provide more detail,
Flow meter type/brand, also what display?

I want to insert two desired date on the op and show amount of milk that passed through the flowmeter for this interval

is the time of day always going to be the same?

You may need to write code to log a count and datestamp and then reset the count every day so each day you will get a datestamp and a count. This could be stored into a DB with say 100 days of data and you could increment the pointer each day or simply push the data down a row each day and fill from the top
