[Addition to 19,169/09.] Anemometers. - The sliding and twisting slotted cylinder described in the parent Specification is replaced by a piston b, which determines the height of the gas passages, and a twisting slide h, which determines their breadth. A space is provided between the fixed cylinder a and the slide h to decrease friction. This space increases the breadth of the gas passages by a constant amount, but is prevented from effecting their height by a rib o on the cylinder a. The roller over which the suspending wire c passes is formed as a cam to compensate for changes in gaseous velocity due to different sizes of gas passages.

GAS FLOW DETECTORS

GAS FLOW DETECTORS A flow detector, for use adjacent a steam trap to detect an unacceptable level of leakage of steam through the trap, comprises a tubular housing 10 substitutable for a standard pipe nipple. The housing comprises a boss 16 which provides a condensate collecting trap 24 in which an electrode 26 is exposed. Immediately opposite the trap 24, on the opposite side of a flow passage 28 provided by the housing 10, is a baffle in the form of a ramp 30 arranged to divert steam towards the trap 24. In normal conditions of use, the presence of condensate in the trap is signalled by an electric current passing between the electrode 26 and the housing 10. Should an excessive steam flow occur in the passage 28, steam diverted by the ramp 30 displaces the condensate from the trap 24 around the electrode 26 and stops the flow of current. A similar detector could be of use in a compressed air line.

Multi-phase flow-monitoring with an optical fiber distributed acoustic sensor

Embodiments of the invention provide a "tool-kit" of processing techniques which can be employed in different combinations depending on the circumstances to monitor multiphase flow in a structure such as a pipe. For example, flow speed can be found using eddy tracking techniques or by using speed of sound measurements. Moreover, composition can be found by using speed of sound measurements and also by looking for turning points in the k-omega {k-ω) curves, particularly in stratified multiphase flows. Different combinations of the embodiments to be described can therefore be put together to meet particular flow sensing requirements, both on the surface and downhole. Once the flow speed is known, then at least in the case of a single phase flow, the flow speed can be multiplied by the interior cross-sectional area of the pipe to obtain the flow rate. The mass flow rate can then be obtained if the density of the fluid is known, for example once the composition has been determined.

Structure of the measuring device for measuring the mass flow of bulk material and the grain-harvesting combine

FIELD: agriculture. SUBSTANCE: grain-harvesting combine has an infinitely rotating transporting device containing planar transport elements, which is partially encircled with a case and which transports bulk material from the area of bulk material grabbing located below to the area of bulk material unloading located above. Bulk material unloaded from the corresponding transport element essentially in a vertical direction by means of a guide surface located in the area of bulk material unloading can move essentially on a circular trajectory and thus decline in the direction of a sensitive surface of the structure of the measuring device for measuring mass flow of bulk material, in particular grain crops. The structure of the measuring device contains the sensitive surface located in the upper part of the transporting device so that in the area of transition from the guide surface to the sensitive surface the flow has tangential orientation in the circumferential direction, i.e. the sensitive surface comes into contact with the movement trajectory of the mass flow. The guide surface is a part of a separate guide section adjacent to a roof section in the area of bulk material unloading forming tangential transition. The distance between the free end of the corresponding transport element and the roof section encircling the transporting device in the area of bulk material unloading in the transport element position, in which there is a distance to the roof section, is selected in such a way that it is possible to fully unload bulk material located on the transport element and provide for even flow input on the sensitive surface. EFFECT: increased accuracy of flow measurement of transported material is provided. 12 cl, 4 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 752 925 C2 (51) МПК A01D 41/12 (2006.01) A01D 61/04 (2006.01) G01F 1/20 (2006.01) G01F 1/30 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК A01D 41/ ...

A method and device for determining the flow rate of a flowing medium according to the plummet principle is characterized by a simplified determination of the calibration data sets in that at least one set of calibration data is recorded with at least one reference medium under at least one reference measurement condition. Then, a position of a plummet which is dependent on the flowing medium is determined under a measurement condition which differs from the reference condition. Here, the set of calibration data is converted from the reference measurement condition to the measurement condition, and from a determined position of the plummet, a measure for the flow rate of the medium is then determined.

Flowmeter for low flow rates - uses measuring wheel rotated by fluid from injector nozzles and contg. markers which pass between cam and photocell

A flowmeter comprises two circular cheeks (91,92) of plastic material which form a casing (90) with a chamber (80) housing an annular ring (20) containing injector nozzles (30). This ring forms a central chamber (70) in which a measuring wheel is located and onto which the fluid is injected tangentially. The liquid enters the main chamber via an inlet (93) and is exhausted via an outlet (94). The force exerted on the wheel is proportional to the volumetric flow. The measuring wheel is transparent and carries markers which pass between a lamp (102) and photocell (101). The frequency of the pulses from the photocell indicates the flow rate.
