Real-Time Dynamic Level Meter Non-Invasive with Optical Sensor

The measurement system for determining the amount of liquid in containers is generally not accurate, due it used the conventional techniques. In others, the measurement is required in real time. This article reports the millimeter measurement of dynamic real-time liquid level, using optical sensors operating in the infrared sensor controlled by automaton. The detection and measurement system is based on a series of modules (Mx) of optical sensors, integrated by a transmitter (Tx) and a receiver (Rx) controlled by a state machine. The sensors array records the intensity of light modulated by the reflection of the radiation caused by the change in the dynamic fluid level in the container. This modulation of light intensity is recorded by the optical receiver. The records of each sensor are treated separately and are finally combined to obtain a more specific and precise record of the liquid level. The purpose of this article is to develop an accurate, economic and quick answer system of measurement and detection, viewed as finite state machine.
