A capacitor probe was developed for locating the level of liquid helium in a Dewar vessel. The problem of the very small difference in dielectric constant between liquid and gaseous helium is solved by complete guarding of the connecting cables and measuring probe except the capacitor. The capacitance meter is set at zero when the capacitor is above the liquid level. (D.L.C.)
