In applications where the liquid level needs to be monitored, a versatile sensor is needed. For car wash application, continuously monitoring the level of liquid soap in a reservoir can prevent customers from an unsatisfactory experience.
The WORLD-BEAM QS18U ultrasonic sensor monitors the level of soap in a tank in a car wash. The sensor is mounted atop the reservoir, aiming through the transparent top. The sound waves bounce off the surface of the liquid, which allows it to accurately sense regardless of the color or shape of the liquid.
