APG's Carwash Sensor | Case Studies


APG has been supplying the car wash industry with reliable sensors for more than 10 years. We manufacture continuous level sensors and discrete level switches to monitor storage and delivery reservoirs for soap and other car wash chemicals, float switches to monitor car wash wastewater, and ultrasonic sensors for vehicle profiling and detection.

Most of the time when we discuss ultrasonic level sensor applications we are talking about their use in liquid level measurement applications, but not all ultrasonic sensors are used for liquid level monitoring. APG’s IRU-2000 series ultrasonic sensor is designed for object detection and profiling. The IRU-2000 Object Detection Ultrasonic Sensor is widely used by carwash manufacturers to control the cleaning process in automatic carwashes to fit your vehicle’s profile.

Have you ever been in an automatic carwash and wondered how the carriage with the brushes and spray nozzle know where your car is and how wide or long it is? Well, there are actually several ultrasonic sensors on that carriage and in the wash bay that read the presence and dimensions of your vehicle. The data is collected from the sensors and sent to a controller used to control the cleaning process.

In the picture above, you can see four of APG's IRU-2000 series ultrasonic sensors. The sensor on the top left detects the presence of the front of a vehicle, as in pulls into the car wash, to start the car wash process. The sensor on the top right and the two sensors at the back-bottom of the picture contribute to vehicle profiling during the car wash process. In the system pictured here, there are two more ultrasonic sensors used for vehicle profiling during the car wash process.

APG IRU-2000 Object Detection Ultrasonic SensorThe IRU-2000 series sensors are perfect for car wash applications including carwash automation, vehicle-presence-detection, distance measurement in the wash bay, and vehicle profiling for wash and drying. The sensor features a water-proof housing allowing it to be used in the heart of your car wash system, and is available in a range of outputs making it is easy to match the range and mounting style needed for your car wash system.

So the next time you are in a car wash, keep an eye out for the ultrasonic sensors. There is a good chance they were made by APG.
