A Radar Liquid Level Sensor is a device that measures the height of the liquid it is placed in and further converts it to electrical signals. Since these sensors use radio wave emissions, they are usually mounted at the top of a tank filled with liquid. The sensor sends a radar signal into the liquid and, in return, receives a reflection of the movement. These sensors then assess the current fill level of the tank depending upon the time taken by the transmitted signal to return. If the time required to receive the movement is more innately, the distance between the sensor and the liquid is more excellent.
It is considered a safe solution even under extreme conditions like pressure, temperature, and vapors. They can also be used in hygienic applications because it has minimal contact with the substance being measured. These sensors have gained immense popularity across industries for it is easy to install and access. And it is suitable for a broad range of industrial applications as it provides accurate readings.
The Uttarakhand State Disaster Response Force informed that it had installed a water-level sensor system at the village Raini of the Chamoli district to alert the villagers.SDRF commandant Navneet Bhullar reported that they had installed one water-level sensor that will sound an alarm when the water level in a river rises above 3.5 meters. The notice will have its audibility range up to a 5-km radius. And in case of a power cut, it will be audible up to 1-km.
The Department of Irrigation in Kerala has decided to install radars in around 163 centers across the state the water level rises in the rivers. The water level of the Pampa and Achenkovil rivers is now kept under record as a part of an experiment for the sensor. It is set to be installed as part of a Central Scheme of the Ministry of Water Resources since the sensor’s considerable advantage is that it can predict floods.
