Abstract


The objective of this paper is to present the feasibility of a self-Rechargeable digital water flowmeter (SRDFM) system for water pipes using latest data processing and wireless communication technologies while causing negligible water pressure drop (head loss).
The system uses a Pelton turbine generator to power the electronic circuit, which process and transmit the signals generated by several flow meters. ZigBee technology was used to process and send wireless signals. Signals from two water meters were acquired, processed and transmitted with only one control/transmission unit during this study. The new system was assessed experimentally reaching a maximum of 80m of wireless transmittance distance at a minimum flow rate of 5 liters per minute for a 16mm diameter pipe, (self-charged).
Keywords: Advanced Meter Infrastructure (AMI), Automatic Meter Reading (AMR), Micro Controller Unit (MCU), Pipe Flow, Self-Rechargeable, Wireless, ZigBee, Data Acquisition Unit (DAQ).
