Abstract

2417. British Thomson-Houston Co., [General Electric Co.]. Jan. 29. Gas meters; air and steam meters.-Apparatus of the U-tube mercury type for measuring the flow of fluid through a conduit has (1) a movable magnet outside the mercury receptacle, (2) a float of magnetic material riding on the mercury between the poles of the magnet and (3) mechanism for recording the movement of the magnet. Fig. 2 shows the sight tube 5 connected to the trailing side of the pressuredifference device by a tube 6 and communicating with the chamber 9 by a small orifice 8. The tube 10 forming the chamber 9 has a depending neck 11 of small diameter, around which loosely fits the flange 22 of the float 21. The bowlshaped mercury receptacle is formed of non- magnetic material with a glass lining 14. The mercury 15 passes up into the chamber 9 and supports a float 17 carrying a pointer 18. Carbon tetrachloride 16 fills the rest of the chamber 9 and extends up into the tube 5 far enough to be visible through the sight-openings 4, Fig. 1. The leading side of the pressuredifference device communicates by a passage 19 with the space in the bowl above the mercury. The apparatus described gives a visible indication of the varying rates of flow of fluid in the conduit. In order to obtain a record of such variations, a magnet 23 carried by a pivoted and counterbalanced lever 26 passes up on the outside of the bowl so that its poles 24 are opposite lugs 25 on the float 21. When a variation between the leading and trailing pressure occurs, movement of mercury can take place freely on the outside of this float and less freely from the inside to the outside of the float by reason of the restricted passage between the projection 11 and the flange 22. The float may tend to lag behind the mercury owing to inertia or friction. The variation in mercury level between the inside and the outside of the float tends to exert an extra force to move the float. The movement of the float causes the movement of the magnet and thus of the marking point 31. Conical bosses 36 on the float 17 act as valves to close the passage 8 or 11 in the case of abnormal deflexions of the mercury, and a stop 35 on the neck 11 arrests the movement of the float 22.
