Fiber optic sensor technology is a high-tech technology developed after the successful use of fiber optic in communication technology. It has the advantages of high accuracy, no electrical signals in place, protection against electromagnetic interference and reliable performance. According to this outstanding advantage of fiber optic, our company and the Chinese Academy of Sciences have successfully developed a high-precision fiber optic level meter. This product has a simple design, substantial explosion protection safety, sensitivity, reliability, high accuracy, can be used to determine the oil level in the tank, the position of the gas cabinet.
