I want to use ultrasonic module JSN-SR04 for detection of water level inside tank. The US module has single sensor for Transmission and Reception of US signals as shown below.
I wonder if US sensor will work reliably for water level detection or if there will be absorption or refraction of US waves inside the water body and little or no reflection of the US waves? How can I check this analytically? I don't have the modules at hand at the moment but I don't know how can I find out about any possible problem in level detection.
The size of water tank is 4 x 5 x 6 (L, W, H) and it is made of concrete. Is it possible that the concrete walls will also reflect the US waves and disturb the sensor readings?
