摘要：

An intensity-based fiber-optic liquid-level sensor for point measurement is described. The sensing principle is based on the total internal reflection of light, which is disturbed by contact with a liquid. The main problems with this kind of level sensor are discussed. The performance of the sensor has been studied using four different shapes of the tips of the sensing elements: conical, rounded conical, second-order polynomial and third-order polynomial.
