In this paper, we describe the water/liquid level regulator using the Floatless method, in general, the installation of an automatic pump system uses a float device, and this is the most common method we encounter. In this design, it is possible to install an automatic pump system without a float so that it is more simple and practical, Floatless sensors can be used in this design, Floatless itself can work only by using 3 sensor wires which are immersed directly into the water reservoir, with a level of water level <50% water motor pump will work together, water level 75% motor pump 2 will die and then continue with motor pump 1 until the water level reaches 100% then motor pump 1 and 2 will stop automatically. In this design, motor pumps 1 and 2 can also be operated manually by directing the selector switch towards the manual control then pressing the red push button (start) and pressing the green push button (stop). This design uses 2 Miniature Circuit Breakers (MCB) 1 phase 20A, 2 MCB 2 phase 6A, 6 relays, 2 Floatless sensors, 2 contactors, 2 Thermal Overload, and uses a 1.5mm NYAF cable. The Floatless sensor has a good level of sensitivity in signaling the water level, it can be proven in this design. The result of this 2 automatic water pump control system is that there is a lack of losses caused by water availability problems and also facilitates activities in water control.
