Low power hydrometry for open channel flows

Inspired by the need to monitor and control the world's largest irrigation and river networks such as those in the Indus River Basin, we have developed a smart water meter to gauge open channel flows. While developing this design, we have overcome challenges related to power consumption, precision, accuracy, calibration, field conditions, data communication and cost. Large scale deployment of such WSN inspired meters will ensure equity of water distribution, better management opportunities and hence reduce water scarcity.
