Layout H (Static head): T (Tilt angle): M (Motor cable): L (Pipeline): B (Drawdown): D (Pipeline inner diameter) Vertical height from the dynamic water level to the highest point of delivery. Angle between the PV generator pane and the horizontal pane. The cable between controller and pump unit. Entire pipeline from the pump outlet to the point of delivery. Ellbows and armatures must be added as an equivalent length of pipeline. Lowering of water level depending on flow rate and recovery rate of the well. 4/4
Well Probe Mechanically Activated Device for Dry Run Protection in Applications with LORENTZ Solar Pump Systems The switch can be used to detect the water level within a well. When the water level in the well dropped below the level of the well probe, the LORENTZ Controller will stop the pump and indicates Source Low LED.
