Abstract
An automated remote water level monitoring platform was designed and constructed for wireless and up-to-the-minute water level monitoring. The system is composed of two platforms: a remote monitoring node (MP), which is composed of an ultrasonic range tinder, a microcontroller, and a Global System for Mobile (GSM) communication module; and a controlling base station (CP), which is composed of the Water Level Monitoring System (WLMS) software that enables remote access, and a database. The performance of the system was evaluated based on the precision of gathered data. reliability of the sensing unit, and reliability of SMS transmission of the cellular network. The uncertainty values of the sensor readings over the maximum detectable range (3 meters) of the sensor are from 0.00cm to 0.09cm on a steady surface. Turbulence in the water surface increases the value of the uncertainty (0.03cm to 0.19cm). Comparison between experimental data and theoretical calculations yield a difference of 0.02cm and 0.03cm for volume flow rates of 1.07 x lern3/s and 8.51 x 10-1m3/s. respectively. System response time varies from 14 to 19 seconds, and is dependent on the strength of the network signal.
