Hello my friend
You helped me a few weeks ago with my two tanks system. I tried to add to this project control of hight of level H2. I added some new parameters and i modified eqautions. Please, could you review my EJS application and help me with this :

Please, could you help me witih adding 2D Drawables element which is valve for control over a fllow. This element will be with cooperation with high of level of TANK H2. On the bottom of my application pannel it could be new elementy with setting of H2 level. And then valve for control over the flow will be controling inflow so level of H2 tank will be stable.

Thanks a lot for helping me !!
