Abstract
755,716. Liquid meters. LUCAS (INDUSTRIES), Ltd., J. Dec. 1, 1954 [Dec. 24, 1953], No. 35879/53. Class 69 (2). A liquid meter comprises a body a having three cylinders, one containing a metering piston n, one containing a rotary valve d, and the third containing a piston t which, when the flow is not to be measured, is moved by the liquid thereby compressing a spring u and connecting an inlet b to an outlet c. The valve has a part i which is driven by a synchronous electric motor. The valve is divided into two equal parts by an oblique partition e and has an outlet g connecting one half of the valve with one end of the cylinder of the piston n and has another outlet h connecting the other half of the valve with the other end of the cylinder of the piston n. The stroke of piston n is controlled by a pre-set abutment o and by a stop p adjusted by a micrometer head q. To measure the flow, the stop p is unscrewed to give the piston n a maximum stroke, and the valve d is driven by the electric motor. The piston t will be moved by its spring to close the direct connection between the inlet and outlet and the whole of the flow will pass via the valve d and the piston n to the outlet. The stop p is then screwed in, reducing the stroke of the piston n, and the increase in pressure will move the piston t until the end of a rod 4 carried by the piston coincides with a mark 6 on a transparent cover 5. In this position, the head of the piston t corresponds with the edge of a port 2 leading to the outlet side of the meter, and the micrometer reading gives the flow.
