We monitor our customers’ water levels using three different methods depending on the type of water assets they have.
1. Closed tanks: We use a pressure transducer sitting at the bottom of the tank. The transducer measures the remaining Litres and percentage of water based on the applied water pressure.
2. Open tanks and troughs: We position an ultrasonic sensor at the top of the tank or trough. The sensor emits sound waves, and as they reach the water, they reflect back on the sensor. The water level is determined based on the time it takes for the sound waves to come back to the sensor, harnessing the speed of sound as measurement. Using this type of sensor in a closed tank would lead to important inaccuracies in the data as the sound waves would bounce back to the top of the tank instead of to the sensor.
3. Dams: We install a pressure transducer at the bottom of the dam linked to a buoy. The buoy plays two roles: it contains the transmitter, and it serves as a visual reminder of where the transducer is located. The pressure transducer measures the water level the same way it does in a closed tank.
