Opis:
In this work a simple new type of flow sensors was developed; the double coil flow sensor. In this sensor two coils are magnetically coupled due to the flow of pure water inside them. The first coil, the primary coil, was supplied by AC voltage in the frequency range 0.5-1 MHz which is the coupling range of frequency for water. The voltage in the second coil, was found to be directly proportional with the volumetric flow rate of the water flowing inside the coils. The two coils can only be coupled in the laminar flow region. In the turbulent region, due to the turbulent chaos and fluctuation the two coils cannot be effectively coupled, and therefore the sensor cannot be used. The temperature of the water was found to have a negligible effect on the coupling, which add a good advantage to the simplicity of the double coil sensor. The working fluid used in this work was pure water. Other fluids are believed to be working as well, most probably at different frequency range, and this will be the subject of future work.

Opis:
Water is one of the basic necessities of life; however, due to the increased growth of population and without any changes of people’s current water consumption rate the world would face water scarcity in the near future. Developing tools and techniques that aim to combat the loss of water quantity becomes a priority action due to it can provide actionable information to the community in its contribution to clean water conservation. In this study, the IoT-based water reduction system has been developed to measure water volume at three household appliances (washing machine, shower, and toilet) by installing flow sensors to those of each pipeline. Each sensor was connected to a microcontroller that sends water volume data and it will be stored in the cloud server. This technology could help users in reducing clean water consumption by: alarming user whenever water volume reaches 75, 85 and 95% of the limit volume for each showering session by installing a buzzer to the shower’s pipeline; limiting the water used for the toilet flushing by installing a solenoid valve for the toilets’ pipelines; and allowing users to access the information of all water consumption through Android-based mobile application. Through this study, IoT technology has great potential to support clean water reduction strategy due to it could save clean water up to 402 l monthly. Application of IoT technology can be started to be installed in such a small house or apartment in which the user can directly monitor their water consumption.
