Abstract: G60.00265 : Liquid height measurement based on laser ranging method
Liquid height measurement plays an important role in many industrial applications. However, most current methods obtain interval time-depending datas. The laser ranging method obtains the integral fluid height, which is very sensitive to the change of laser intensity. The measuring structure is a vertically fixed multimode optical fiber as illuminating and receving device. Place the foamed plastic platform on the liquid and paste a mirror as a reflector on the platform. The light emitted by the optical fiber is reflected and received, which has a gaussian curve relation to the distance between the fiber and the liquid.
