INGENIOUS.
NEW FLOW* METER. Many ingenious devices have, been invented to measure the rate which water or other fluid is flowing. The most effective is a new type produced by a leading British firm of instrument makers. The essential part of thfe instrument is a small paddle wheel placed inside the pipe so that it rotates as the fluid moves along. This paddle wheel has attached to it a magnet, and in a separate steel chamber immediately outside there is another magnet which rotates like the first. When the paddle wheel moves and carries its magnet round with it,/ the movement of this magnet pulls the second magnet round; and the speed of this second magnet therefore indicates the rate of the flow in the pipe. The advantage of this arrangement is that the indicating part of the mechanism is quite distinct. The instrument is therefore particularly well suited for use where crude or hot oil is employed.. »oe makers suggest that this instrument is well adapted to measuring the rate of flow of oil in lubricating systems, and also the flow of. oil fuel or cooling water in oil engines.
