Abstract
This thesis aims to accurately measure the amount of delivered water from the water- station to the remote citizen houses, where the water networks are not available. A simple design is proposed. A non-experienced operator can run and use it. The proposed system has been applied in the water station of Matrouh governorate. This water company used to have a waste quantity of water 44000 m3 monthly. By applying the proposed simple system waste water is reduced to null. The proposed system uses an AVR ATmiga2560 arduino, a keypad, a liquid crystal display (LCD) and an internal memory. The idea is that the operator starts the system and enters the quantity of needed water and then, a signal is sent to the arduino which sends a signal to the electro-hydraulic valve to open. The water flows into the customer tank. The flow meter sends an electric signal to arduino indicating the water speed. The arduino calculates the water quantity delivered to the tank and its price. When the needed quantity of water is reached, the arduino sends a signal to the valve to stop. The quantity of supplied water and price are sent to the LCD and a storage medium for simulation and reports. The proposed system is very cheap, easy to use and effective. It can be an alternative to the traditional SCADA systems.
