Setting the SIEMENS SITRANS P320/420 Pressure Transmitter for Level Measurement 

Hi Ahmed, this answer comes a bit late, but could maybe be usefull. :) The Y01 option is for the measuring range settings. To mention what you need, you just have to add the calibration between brackets. The correct model you would need is this one : Model : 7MF0340-1GL01-5AF2-Z C11+E00+Y01 {Y01: -60 ... 60 mbar}. Hope it helps !
