The aim of the invention is to improve such a Durchl'lußanzeiger in the sense that he Installation in vertical pipelines.

For this purpose, the flow indicator according to the invention is characterized in that the Pipe from a casting having channels which form the flow supply and discharge line under a diaper smaller than 'K) to the Fluid supply and drainage line axis directed obliquely upwards and the housing accordingly inclined airüeor nc! is.

The invention is based on the surprising finding that it is essential for proper function of the flow indicator it is not necessary that the tube protruding into the housing with its ball containing seat is aligned exactly in the vertical. The ball loosens when the flow velocity disappears also then back to your seat. when the tube in the invention Way at an angle to the vertical.

In the drawing, an embodiment of the subject matter of the invention is shown.

The figure shows a flow indicator according to the invention in axial section, in a side view.

In a casting 1, the Rohranschlussflanschcn on both sides 2 carries, two axially aligned channels 3, 4 are formed, one of which is the Fluid supply line and the other the Forms fluid discharge line. At the Guß-Muck I an obliquely outgoing approach 5 is formed, in which two flow channels 7, 8 separated from one another by a solid partition are formed are. One of these flow channels protrudes in the shape of a tube into one which is connected at an angle to the casting I Housing 10 which is covered by a transparent hood 11. The arrangement is made in such a way that that the tubular protruding into the housing 10 channel 7 or 8 in the Rohrmündungsbcrcich one in the form of an extension of the clear pipe diameter formed Sii / 12, in the

Claims (3)

Patent claims: I. Durchikiianzeiger for in vertical Rieh development from above and below, exiting again fluid with a housing covered by a transparent hood, into which the fluid supply line protrudes into the housing with a pipe in the Rohrmünduigsbereich in the form of an expansion of the clear pipe diameter ::.he. ausgebildc th seat and near the pipe the Strö mungsinittelabfuhrleitung open and in which a freely movable ball is inserted into the seat, the diameter of which is greater than its distance from the surrounding housing or hood walls, characterized in that the tube of one of the Sirömungszufuhr- and -abfuhrleitung forming channels (3, 4) having casting (\) at an angle which is smaller than ¹ H). to the fluid supply and discharge line axis (14) is directed obliquely upwards and the housing (10) is arranged correspondingly at an angle. 2. Flow indicator according to claim 1, characterized in that on the casting a obliquely outgoing approach (S) is formed in which two by a partition (6) from each other separate Durchflußkanälc (7, 8) are formed, one of which with the fluid supply-I itation and the other is connected to the fluid discharge line and of which the one opens into the seat (12) and the other freely into the housing (10). 3. Flow indicator nych claim I or 2, characterized in that the angle between the fluid supply and discharge axis (14) and the axis of the seat (12) is about 60 ".
