A vacuum loader truck that includes a storage tank that can be loaded and unloaded with debris. The vacuum loader truck includes a debris level sensor that generates a sensing beam to detect the level of debris within the storage tank. The level of debris within the storage tank is determined by a control module and displayed. The debris level sensor may be an ultrasonic sensor that generates a sensing beam that is reflected off of the top surface of the debris within the storage tank. The control module determines the height of the debris within the storage tank based upon the time delay between the generation of the sensing signal and the reflected signal. The control system further includes a particle sensor to determine whether particles are entrained in the airflow from the storage tank. A pair of pressure sensors are located on opposite sides of an air filter to sense the differential pressure across the air filter. Based upon the signals from the debris level sensor, the pressure sensors and the particle sensor, the control module can control the operation of the vacuum loader truck.
