Level Transducer

If we have a 4-20mA / 6meter level transducer in a 4.5meter tank, what is the easiest way to show the level on the text display of the easy and also scale it so 4.5meters is 100%.

Hi srd,

you can use an 500Ohm resistor, better an current to voltage signal converter ( https://www.google.com/aclk?sa=L&ai=DChcSEwiE-Myn-OrrAhWW7e0KHdz1Br0YABAMGgJkZw&sig=AOD64_0d13nAQzlOt07A4gKNJxx6cx4uYw&adurl&ctype=5&ved=2ahUKEwiFnMCn-OrrAhXaNOwKHXp3BREQvhd6BAgBEEY ), to make a 0-10V signal.
Then scale with LS Funktion the analog Input to Level in Meter. With an D-Block you can show the LS-output on E4 Display.
