Medium`s e.g. water, flow rate monitoring device e.g. flow monitor, for e.g. pipe, has nozzle body with two cross sectional openings arranged one behind other in flow direction, where one opening corresponds to head surface
The device has a paddle (20) supported in a housing and pivotable around an axis, where a signal is released by a paddle during displacement of the paddle from its initial position. A paddle head (22) is arranged in an area of an outlet of a nozzle body (10), which is arranged in a pipe (2). The nozzle body has two cross sectional openings (11, 12) that are different in cross section and arranged one behind the other in a flow direction, where one opening corresponds to the surface of the head and the other opening is larger than the former opening.
