Inside this paper the reader can read information around signal processing, calibration, digital signal processing, response, arrangement, sensors, error, ultrasonic measurement, ultrasonic sonar sensors, and frequency. This paper gives you explanation about flow measurement, ultrasonic, accuracy, the ultrasonic sensor, the ultrasonic flow, ultrasonic sensors, transducer, ultrasonics, design, and pressure sensor.
Lots of things related to methods, sonar sensors, ultrasonic transducers, resolution, signal, sensitivity, principle, ultrasonic sensor, ultrasonic signal, and sensor are explained in this paper. Below are excerpted from the paper:
Ultrasonic Sensors i n A ir are Intelligent Sensors, which use wave-propagation phenomena i n air to measure physical or chemical variables. With accordance to the influence principle, two main types of ultrasonic sensors can be differentiated. P ropagation-Pafh Sensors decode changes on propagation to get a fast measurement of temperature, pressure variations or gas concentration. Most important are ultrasonic flow sensor e.g. for engine intake air or for aidgas measurement. Distance-Sensors detect echoes from objects and evaluate their propagation time and amplitude. Examples are distance meters a nd presence detectors.
Additionally, the paper explains information things like neural network, ultrasonic presence sensors, measurement, distance sensors, object recognition, flow velocity, ultrasonic distance sensors, temperature sensor, transducers, and ultrasonic flow measurement.
