If I keep the ultrasonic sensors (40KHZ/25KHZ) in a sealed plastic container, will they still measure the distance? I want to measure the water level in a tank about 10ft depth and I don’t have the water proof ultrasonic sensors available at my place. Any suggestions are welcome.

Question on ultrasonic sensor!

.Not sure if its true, that's why I was looking for the water proof sensors, but unfortunately those are not available here.

what about automotive sensors?
