Abstract
PURPOSE:To prevent the explosion and the corrosion and at the same time increase the detecting accuracy, by constituting a liquid amount detector in such way that the right-angled prism having a smaller refractive index than the liquid in the container is provided at the fixed position in the container and then both the light source and display optical fibers on the slope of the prism with the cross sections touching to each other. CONSTITUTION:Right-angled prism 3 having a smaller refractive index than the liquid in the container is provided in the container so that slope 3a may coincide with the lowest reference residual liquid surface. And then light source and display optical fibers 3 and 4 are provided to upper surface 3a of prism 3 so that their cross sections may touch each other. In case liquid 1 exists higher than surface 3a, the light led to prism 3 receives no full reflection on the right-angled surface and thus no light reaches the tip of fiber 4 to have no functin as a warning lamp. When the liquid surfae lowers less than surface 3a, fiber 4 functions as a warning lamp. Thus the explosion and the corrosion can be avoided, at the same time increasing the detecting accuracy.
