How to Use an Infrared Photoelectric Sensor for Water-Based Liquid Detection

One of the most difficult photoelectric applications involves sensing the presence or absence of clear fluids in clear bottles. Online weighing systems, low-contrast sensors and ultrasonic sensors are some methods used to detect water fill level but these methods are expensive, or not always very reliable. Learn more about how Banner’s QS30 H2O photoelectric sensor uses a unique optical property of water to reliably detect the presence or absence of water.
