Abstract
In this paper, a practical optically powered hydrostatic tank gauging system with optical fiber is presented. It combines the advantages of optical fibers with the micro power consumption sensor. Two multimode fibers are connected between the readout and the sensor, so it has external optical attributes. Optical energy transmitted from the readout is converted to electricity at the sensor. Digital data from the sensor is transmitted over the fiber to the readout. The parameters measured include the liquid level. the interface between water and oil, the tank storage.The paper gives results measured above parameters by means of the semiconductor strain gauges.
