摘要： The invention relates to a mass flow pickup (1b) having a thin, disc-shaped pulse detector (25b) with through-flow apertures (40b) floating in a fluid in a working chamber. The pulse detector (25b) is suited in weight and flow properties to the characteristic of the fluid. Counterpoise components (77, 78) can be coupled to the pulse detector (25b). In addition, at least one induction coil (11b) and a magnetic region (45b) acting on said induction coil (11b) is allocated to the pulse detector (25b). Furthermore, there are sensors (17b, 18b) which record movements of the pulse detector (25b). Sensors to measure pressure and temperature may be fitted in the working chamber (46b). The pulse detector (25b) can be guided in the longitudinal direction of the working chamber (46b). It can, however, also be rotated with the suitable adaptation of the working chamber, its guide, the induction coil, the magnetic region and the sensors.

摘要： A fluidic flow meter comprising a fluidic oscillator having an oscillation chamber, a power nozzle for issuing a jet of fluid into the oscillation chamber, an outlet for issuing fluid from the oscillation chamber. A bendable fiber optic wave guide loop has a section adapted to lose light, as a result of flexing or bending, is mounted in a flow path in the oscillation chamber and subjected to oscillatory flow of the fluid. Light is injected into one end of the fiber optic wave guide and a detector senses the oscillatory loss of light in the fiber optic wave guide as a measure of fluid flow through the fluidic oscillator.

摘要： A liquid flow measuring device has a deflector (31, 69) slidably mounted relative to a cylindric inlet of the liquid to be measured, for a minute displacement along the axis of the inlet conduit. The deflector is exposed to the static pressure created by the fluid. It has a concavely shaped deflection face shaped to reverse the flow of the incoming liquid. The flowing liquid creates a dynamic force vector at the deflector in the direction of the axis thereof. The dynamic force at which the deflector is urged by, and in the direction of, the incoming flow is sensed by an electric pressure cell (42, 81) whose electrical output is then directed to a suitable indicator (47) or control apparatus. The device presents a simple arrangement. Yet, it is sensible to even minor variations in the rate of flow of the liquid due to the fact that virtually the entire flow participates in the generating of the pressure active at deflector and thus at the cell (42, 81).

摘要： A fluid flow meter for measuring fluid flow rate, comprises an inlet port (22), an outlet port (21), and a conduit element (20) between the inlet and outlet ports (22, 21) through which the fluid flow passes and is caused to change direction. The active conduit element is mounted so as to be movable by the reactive force on the conduit element (20) generated by the momentum of fluid flowing through the conduit element (20). The meter (23) comprises means to indicate the reactive forces on the conduit element (20) to provide a signal indicative of fluid flow rate, and means to balance out the static fluid pressure within the conduit element (20).

摘要： An improved electronic rotameter (8) which utilizes a point source of radiation (15) at one side of the rotameter (8) and an opposing array of detectors (17). A movable float (10) has a shadow-defining edge which casts a clearly defined shadow line across the detectors (17) for a range of positions of the float (10). This construction provides improved resolution which can be accurately analyzed and integrated with time to determine flow rate.

摘要： A flowmeter comprises a chamber having a centerline (15), an inlet nozzle (22) directed along the centreline for the fluid whose flow is to be measured, a splitter (23) located on the centreline and having an apex (24) facing the nozzle, each side of the chamber on each side of a median plane including the centreline being divided into a feedback channel (28) and an outlet channel (29, 14) with an apex (53) therebetween, the feedback channel (28) extending from the apex (24) of the splitter to a location beside the mouth of the nozzle. In order to improve uniformity and sensitivity, particularly at flows corresponding to low Reynolds numbers, the distance a from the mouth of the nozzle to the splitter (23) is made greater than the distance c from the mouth of the nozzle to the apex (53) between the feedback channel and the outlet channel.
