Many - fish finders, many sonar devices.
An altitude sensor provides altitude data to within 30-centimeters. An echo sounder is a device for determining the depth of the seabed or detecting objects in water by measuring the time taken for sound echoes to return to the listener.
Ultrasonic testing can provide depth measurements in materials by analyzing the time it takes for the sound wave to travel to a reflecting surface and back. This allows for detecting defects such as cracks, voids, and thickness variations at different depths within a material. Ultrasonic testing is commonly used in various industries like aerospace, construction, and oil and gas for its ability to assess the integrity of structures and components.
Due to their short ranges, ultrasonic (>20khz) frequencies aren't used for ship or submarines' primary Active Sonar systems. Though the actual frequencies used are classified, I can say that they're nowhere near the ultrasonic range. Submarines do employ ultrasonic frequency detection systems that are passive sonar based, but they're primarily for detecting active sonar from homing torpedoes. They're also annoying for detecting any bottle-nosed dolphins in the area when you're at Periscope Depth.
Sonar is used in various applications, including underwater mapping, navigation, fish finding, underwater communication, and military purposes such as detecting submarines. It works by emitting sound waves and analyzing the echoes to determine the location, size, and composition of objects underwater.
The Wade Sensor in Land Rover vehicles measures the depth of water encountered while off-roading. It uses ultrasonic technology to detect the distance between the vehicle and the water surface, providing real-time data to the driver. This information helps assess the safe fording depth and alerts the driver if the water level approaches a critical threshold, enhancing safety during water crossings.
