Water Instrumentation

Instrumentation forms an equally important component of the project. Measuring the water quality of the borewell and lake water, measuring the static water level of the borewell, understanding the weather parameters locally are some of the components which require use of several instruments. There are different set of instruments available in the market and we have tried and tested couple of them. The section below would elaborate on each of the technology:

Water Level Sensors

This is used for measuring the static water level in the borewells. This equipment has a tape marked in feet and meters and wound around a metal spool. One end is connected to a circuit and the other end to a probe. When the tape is lowered into the borewell and the probe hits water, the circuit is complete and sets off a buzzer and/ or a light. The whole equipment is powered by either a 12v battery or a couple of 1.5v cells. You can read more on this Water level sensors 

  

Weather station

An automatic weather station (AWS) attempts to monitor weather related and specifically rainfall data at a very localized level. The installation was done by Yuktix (a start up based in Bangalore). The system has two main components - 1. The sensors for Atmospheric Pressure, Humidity, Temperature and the rain gauge 2. The controller which quantifies the data recorded by the sensor and broadcasts it to a cloud based server. You can read about the installation of automatic weather station Weather station installation at Rainbow Drive layout

 

Portable/Handheld Water quality testing meters

For now, following meters have been procured from different vendors and regularly used on the field.
A. pH meter
B. TDS meter
C. Electrical Conductivity (E.C)
D. Salinity
E. Dissolved Oxygen (DO) meter
