The Nash Meter.
The Nash water meter, which is herewith illustrated, is the product of a careful series of experiments, which were carried on long before any other meter of a similar type was placed upon the market; and it is now offered to the public, under the belief of the makers that they have a practically perfect machine.
The principle of action in the Nash meter being controlled by two cones the friction is reduced to a minimum. The meter is substantially made, has no thin castings liable to spring or become distorted, and is so designed as to be extremely rigid. The workmanship is of a superior grade, and the meter needs no change gears.
The measuring chamber in this meter has this advantage that its passages are very large and it offers but little obstruction to the delivery of the water or in the action of the water in the measuring chambers. Upon this fact is based one of the claims for the superiority of the device.
The water passages in the Nash mater are, it is claimed, also so proportioned to each other that the piston is water balanced at all rates of flow, so perfectly that it always clings to its measuring chamber and takes a definite path without excessive pressure. This is shown by the fact that no guiding appliance is used. The advantage of this perfect adjustment and temper of the water passages to the durability of the meter, and also the ability of the meter to pass over obstructions without injury, are features whose value will be appreciated.
The internal gearing of the Nash meter is strong and durable. No light or flimsy parts, which require delicate manipulation are used. The measuring part of the meter has only four strong castings, so substantially made as to stand any reasonable handling by ordinary workmen. There are no parts requiring careful adjustment, and they can all be easily put together. The Nash meter is also noiseless, and, it is claimed, will run on exceptionally light pressure.
