Abstract
Abstract
We propose a new type of liquid hydrogen level sensor and evaluate a prototype system with liquid nitrogen. The level sensor acquires images of the liquid surface, which is illuminated by point sources of light, and estimates the liquid level by image processing. This scheme allows us to avoid immersion of the sensor body into the liquid and also eliminate the necessity for any electrical wire connected to the sensor body. The accuracy of the prototype sensor is estimated to be ≈ 4.8 mm in our experiment using a 10 liter liquid nitrogen vessel.
