American SENIX Ultrasonic Level Sensor
The ToughSonic 3 ultrasonic sensor has a sensing range of 3 feet (91 cm). If you need a smaller sensing range or a smaller ultrasonic beam size, then the ToughSonic 3 is a great choice. The ToughSonic 3 features the same 30 mm stainless steel housing as the ToughSonic 14. It has a 1.75-inch (4.5 cm) sensing range and a narrow ultrasonic beam width for use in tight spaces.
