Abstract
27,268. Glover, W. T., and Meters, Ltd. Dec. 15. Meters.-To prevent a sudden increase of pressure in the gas-main from shutting-down the inlet valve of a wet gas-meter, an equilibrium valve b, c, is substituted for the ordinary single valve disk mounted on the float stem, and the float is enclosed in a chamber e having a small gas-inlet aperture around the float stem f, so that a sudden rise in pressure cannot depress the valve or the water in the float chamber.
