摘要： In an apparatus for weighing continuously flowing flowable material, in which the mass flow is determined as a function of measurements of forces exerted on at least one plate (1) in contact with the flowing material, the main novel features are that the apparatus is adapted to perform at least two of said measurements in substantial dependence of the distribution of weight, such as between third points (A, B), on a basically rectilinear inclined plate, on which the material flows slidingly. With this arrangement, the results of the measurement may be used for creating an expression of the mass flow, the accuracy of which is independent of the flow velocity, density and friction of the material.

摘要： The measuring device (2) comprises a sensing element (4) communicating with the process substance as well as a lever-like transfer element (7) connected with the sensing element and arranged to transfer the force acting on the sensing element due to the process substance to be measured and/or to transfer the movement of the sensing element effected by the process substance to a measuring element (6) using the torque applied to the transfer element (7) about its fulcrum. The through hole (8) has a diaphragm (14) of elastic material covering the hole, being in engagement with the transfer member (7) in the position substantially perpendicular to the longitudinal axis thereof and acting as a sealing member separating the portion outside the process substance from the process substance. The diaphragm is mounted between two elastic gaskets (16) located in the side region of the through hole (8) in order to allow the free movement of the diaphragm in the direction of its main plane for eliminating tension forces applied to the diaphragm by the translation and the rotation of the transfer element (7) and causing measurement inaccuracy.

摘要： In a measurement device for determining the rate of a flow of bulk materials, the bulk materials are supplied to a vertical deflecting pipe after flowing through at least one braking device. When the bulk materials enter the deflecting pipe, the latter is deflected sideways. The deflecting pipe is curved, so that the bulk materials fall freely a second time upon the curve of the deflecting pipe and the lateral deflection of the deflecting pipe is increased.

The impact plate (32) is aligned with the inlet chute (18) so that the material entering the housing (12) strikes the impact plate (32). The impact plate (32) deflects the load cell (40) in a measurement direction (64) to change the signal from the load cell (40) based on the flow rate of material. The flowmeter (10) further includes a stop (56) for biasing the load cell (40) in the measurement direction (64) to establish a preload condition on the load cell (40), a load cell mounting bracket (34) located outside the interior region (15).

摘要： A flow level measuring device for measuring quantities from a moving source of material is disclosed. The flow level measuring device includes an Electronic Control Unit (ECU) (28), and the following ancillary components: a programmable display (32), a Motion Detector Assembly Group (MDAG) (25), and a Level Detector Assembly Group (LDAG) (23). These assembly groups detect horizontal and vertical displacement of a material stream, respectively, and encode the displacement data. The encoded data is sent to ECU (28), whereby the encoded data is processed according to an algorithm. The manipulated data is then transformed into a suitable data stream that can be displayed on a viewing screen or other suitable display device, providing real time volumetric measurements not available in the prior art.

摘要： An impulse momentum dry flow sensor includes a plate (24) for mounting in a "dead-end" turn of a granular material carrying conduit, a leaf spring suspension to limit its movement to substantially a horizontal plane, and a linear force transducer (20) to measure the force applied to the plate by granular material negotiating the turn. The linear force transducer (20) includes an inclined plate (24) mounted in a chute (22) to be impacted by a flow of granular material, the plate being supported by one or more leaf springs (150) from the chute. An actuator rod (34) is mounted to the plate and extends to a servo mechanism (36) which generates a force to resist deflection of the plate, the actuator rod (34) being supported by a pair of spaced leaf springs (48). The servo mechanism includes an electromagnetic force generator (64) to apply a force to the actuator rod (34), with an electronic circuit (176) to produce an electrical current in response to a force applied to the inclined plate to energize the electromagnetic force generator.
