Precision Ultrasonic Level Detection Unit

This precision ultrasonic level detection unit enables accurate, repeatable measurement of liquid height in sealed or open-top containers found in household appliances. Its physical dimensions are 45 mm in diameter and 28 mm in height, with a mass of approximately 65 g. Built with a plastic enclosure suited for clean indoor environments, it runs on DC power from 10 V to 36 V and maintains average current consumption below 15 mA. The DS1603NF V1.0 generates an analog output voltage linearly related to the time-of-flight of emitted ultrasonic pulses — delivering stable performance even with changing liquid surface tension or minor foam formation common in UK tap water conditions.
