confirmation of Analogue scaling

Hi All 

I am continuing my learning of programming and have a couple of question regarding a part of a program that i am working with (see attached file)

i want to make sure that my scaling of the input is correct when displaying the levels and in relation of the water in the tank.

So to the bottom of the level sensor its 2m and to the overflow of the tank its 1.8m and then with the switching points in the middle.

So how do i confirm that this is where i am correct with scaling 

also how would i change it from the meters of water in the tank to the liters used if the tank is holding 9000 liters  

Thanks

Hi

so in my bar graph i have changed the 2.3m to 2m and the scaling from 205 to 200 B001

am i correct 

Hi 

This is great i have had a go on my bench setup and works a treat 

Thanks for the Help
