The U53 Ultrasonic Sensor requires no maintenance and is designed to provide years of uninterrupted service. To minimize temperature effects, it has a short blocking distance or less than 10 inches （250 mm） so the sensor can be installed close to the water surface. Measuring Range: Depth: 0.82 - 19.68 ft. （0.25 - 6.0 m）. Air Temperature: -40 to 176° F （-40 to +80° C）. Mechanical: Construction: NEMA 6P （IP68） plastic PST body with integral temperature sensor. Cable: 100 ft. For use with Hach sc200 Universal Controller with Ultrasonic Flow Sensor.
