M33 Patch Underwater Obstacle Avoidance Sensor

M33 patch underwater obstacle avoidance sensor (aluminum housing, direct cable outlet without aviation connector) is waterproof and durable, with more accurate distance measurement, simpler installation, stick-on and ready to use, intelligent obstacle avoidance, saving worry and effort. Works in turbid/flowing water as well, prevents false triggers and saves maintenance, IP68 waterproof without worry of immersion damage, strong anti-interference with stable signal, small size and no space occupation. Underwater robots → reduce collision maintenance costs by 50%. Applications: piston pump cycle count measurement, bottom-mounted on gas cylinders for 24-hour monitoring of liquid level inside gas cylinders, and externally mounted at the bottom of domestic water tanks to measure internal liquid level.
