Abstract

291,128. Hatfield, H. S. Jan. 29, 1927. No Patent granted (Sealing fee not paid). Indicators actuated by pressure of head of liquid. -In a liquid level indicator applicable to petrol tanks, the pressure is measured at a point in the suction pipe through which the liquid is withdrawn, the gauge being connected by a pipe having a small air leak, and an enlargement near the junction with the suction pipe. A small chamber 3 is connected to the suction pipe 2, and to a suction gauge 5 which indicates the height of the liquid in the chamber 3 above the level in the tank. A small amount of liquid enters the chamber 3 when suction is applied, but afterwards varies little in level. Any loss of air may be replaced by a porous plug 6 or by providing the union of the pipe 4 with a porous washer. The chamber 3 may be replaced by a horizontal coil of piping, so that the liquid level in it does not vary although the surface may move. In another modification (Fig. 4, not shown) an additional tube may connect the chamber 3 with the tank, in cases where the suction pipe has a non-return valve at its' lower end. A liquid manometer may be used in place of the gauge.
