Abstract: This paper presented a fiber optic liquid level sensor circuit with an absolute code based on an image sensor OV6630 and a high speed single chip 8051f120. OV6630 was used to acquire the image data of optical fiber which had been modulated especially by liquid level. Then the image data was processed by 8051f120 and orderly sent to a display module. This circuit has the capability of accurate data acquisition and high data processing speed. It can be broadly used in the dynamic test and monitor, and it also has important research significance in many liquid level measurement fields with special requirements of high accuracy and explosion protection, for example, the level measurements of petrol, aviation kerosene, etc.
