It is an IoT-enabled water measuring device for open field channel to measure irrigation water flow rate, depth of flow and the volume. It is a modified flume with a unique throat section to ensure the critical flow and was designed and calibrated through hydraulic flume testing. An ultrasonic sensor is mounted besides a digital processing unit using the microcontroller and the data transfer protocol for data transfer using IoT.
This device measures flow depth, flow rate, and cumulative water volume under different flow regimes in an open channel. Therefore, a desired quantity of water as per crop water demand can be provided to the crop to enhance the water productivity.
It is a modified flume with convergent, a unique throat and divergent section to ensure the critical flow and the dimensions to fit into the field channels of canal commands in India. An ultrasonic sensor is mounted besides the the micro-controller and the data transfer protocol for transfer and display of data.
Suitable for the field channels in any canal command in India and assist the stakeholder in release of water as per the crop water demand.
Under standard testing conditions, the device performed with ± 5% accuracy and statistical parameters viz. R2 (0.85-0.92), RMSE (0.16±0.25) and MAPE (2.2 ± 1.6), and were within acceptable limit and in line with the device generated and actual measurements.
Presently, the device is under subsequent evaluation at a pilot scale in the field channels in different distributaries of three canal commands in Odisha State.
The device is portable and mounted with low cost sensing systems and can be fitted to the field channels in canal commands of the Country for crop water demand based irrigation water supply. The device is installed and is under field evaluation at three different locations in the canal commands through a pilot project funded by the CAD division, MoWR, GoI.
The device was developed under collaborative programme involving scientists and student of ICAR and the contact persons for development, calibration and ongoing evaluation are:
