Abstract
We are seeing some clear trends in water distribution and management systems which are especially true in the irrigation market where water is a precious, but sometimes scarce resource. Among these trends are usage regulations, advances in water monitoring equipment, data logging capabilities, and Supervisory Control And Data Acquisition (SCADA) systems or wireless telemetry systems. These trends require more sophisticated closed-pipe flowmeters with better accuracy, reduced maintenance, and less complicated retrofits into the existing piping system. New innovations in ultrasonic and electromagnetic flowmeter technologies bring battery-powered systems to remote locations where power is limited or too expensive to install. These new flowmeters allow full operation and offer extended battery life of up to 6 years. They also have beneficial features including alarm call up via cell phone modules, SMS text messages, drive by readings, and even web-based data transmission.
