Hey .

could please anyone help me with this tast

I have 3 pumps to empty a tank,

when the water go to level 1(sensor 1) I want first pump start, and when water up in level 2 (sensor 2) then start 2nd pump and when the water goes up to the level 3 (sensor 3)so start 3rd pump. all the pumps should stop when the tank is empty in the base level (sensor 4)

but next time the water rais up to the level 1 so the pump 2 start not pump 1 then when the water in level 2 so pump 3 start then when water in level 3 pump 1 start.

and next time water go up again to the leve 1 so pump 3 start and when water in levet 2 pump 1 starts and in level 3 so pump 2 starts ...

could you please help me, how I will make it with TIA16

Hi,

-in your first network you can define a counter that increases with a rising edge (Pulse) from the sensor level 1.

-in your second network make a comperator if the counter is 1 and make your first logic nr 1.

 -in your third network make a comperator if the counter is 2 and make your first logic nr 2.

-in your fourth network make a comperator if the counter is 3 and make your first logic nr 3.

(with the  edge from the sensor 4 reset also the counter to be 0. 

thanks Friend Omar   I will try it 

الف شكر اخي عمر ساجربها ..

لكنني لست خبير على البرنامج ساحاول التجريب

 could you please show me that as picture ? 

hey again my friend

thanks for you, but is this right ?

but where I should i put the number that comes from counter in the comperator operation... ?

 Go to the top of the forum webpage and type the word pump, the result will contain threads with similar question.

What happens when the water level goes up to level 2 sensor and motor 2 runs with motor 1 then after a while it drops below sensor 2 but higher than sensor 1 and stays there for a while then goes up again above sensor 2 or sensor 3 then down above sensor 1 or sensor 2 then up again. Should that influence the relationship between sensors and motors?

Is this a school project and if yes how much is riding on it?
