Abstract: 730,403. indicating liquid level by means of radio-activity. TEXACO DEVELOPMENT CORPORATION. Oct. 15, 1952 [Oct. 16, 1951], No. 25832/52. Class 40(3). The level of liquid in a container is detected by means of a detector receiving radiation from a source of penetrative radiation so supported within the container that part of the source is above and another part of the source is below the lowest liquid level. As shown, the source 26 is elongated in form and varies in intensity along its length so as to make the detector output substantially linear with the depth of the liquid. It may consist of a rod of material sprayed with radio-active paint of increasing thickness or of a number of small sources of increasing radiation strength. Alternatively the source may consist of sheets of radio-active material cut as shown in Fig. 5 and rolled about the ordinate AA or the source may be used in the form of a plane area of such a geometric shape that the effect of each element of the rod on the detector is the same. Thus the intensity of the radio-active source may be proportional to the square of the distance from the detector. A source of gamma radiation such as radium, or of neutrons such as a mixture of radium or beryllium may be used. The Figure shows the detector situated outside the container but it may be situated inside and may be situated near the mid-point of the radio-active source. The source may, for example, consist of two conical elements with their apices opposing, the detector beings located near these apices. The source may consist of a shell filled with radio-active material. In the embodiment of Fig. 3 (not shown), two separate radiation sources are used, one part below the highest liquid level and the other just below the lowest. Specification 612,899, [Group XL (a)], is referred to.
