Hi. I have found the problem. This is a profilux error. The logical programming works perfectly and does not dosify the liquid but the profilux continues discounting the milliliters at the time that marks the timer to him. If you dose manually through the program or the web page also discounts the ml even though it is not really dosing because the logic operator is not fulfilled. This makes the volume of liquid is not correct and profilux do not calculate well the amount of liquid in the container producing false alarms because profilux thinks that the liquid is ending when it is not. The quantity of liquid data being totally false. I would like someone from ghl to pick up this bug and be repaired in future versions. Thank you
