A precision measurement device includes a housing and a rotor. A feed inlet is provided at an upper side of the housing. A discharge outlet is provided at a lower side of the housing. The rotor is connected to a motor. Three rings of measurement recesses are formed on the outer wall of the rotor in correspondence with the feed inlet and the discharge outlet. An upper end of the feed inlet has a trapezoid shape which is narrow at the top and wide at the bottom. The discharge outlet is disposed off-center at an ascending position of the rotation cylinder, achieving an accurate measurement effect.

A method and apparatus to monitor the weight of a silo or tank is disclosed. The system is adapted to be attached to a leg of the silo and comprises a load cell, a support member anchored to the ground and a lifting device attached to the load cell and to the support member. The load cell comprises two extremities that are attached to the silo leg and comprises an aperture there between. The aperture is preferably threaded to receive the lifting device, such as a bolt. The bolt is rotated using a tool as to induce a movement of the load cell along the axis of the bolt thereby lifting the load cell and the attached silo leg. Strain gauges are attached to the load cell to measure the variation in an electric or optical signal that is translated in human readable data using a monitoring device.

A dual-barrel powder dispenser is provided. The dual-barrel arrangement may offer a highly-accurate, and highly efficient system and method for dispensing a consistent amount of powder. A controller in communication with the interface may determine the speeds at which each barrel rotates in order to dispense a volume and weight of powder from a hopper to a receptacle. A scale may monitor and determine the total weight of powder dispensed into the receptacle resting on the scale. The entire assembly may be self-contained in a single integrated body.

The present invention relates to a gravity-box-based snack vending apparatus including a storage container for storing snacks and a delivery module. A bottom of the storage container is in communication with a material outlet of the delivery module. The delivery module includes a discharging apparatus housing and a transmission apparatus. The transmission apparatus includes a driving gear driven by an external force, a driven gear engaged with the driving gear, and a rotating wheel structure coaxially rotating with the driven gear. The rotating wheel structure includes a rotating shaft and blades mounted on the rotating shaft. The rotating shaft and the blades are provided across a material outlet. Granular materials fall on the blades, and two front and rear blades in a static state just block the material outlet.

A weighing method has an automatic micro-calibration function. In the method, an automatic adjustment is performed by a self-calibration weighing module. When the result of the adjustment does not meet a requirement, an automatic calibration is performed by the self-calibration weighing module, followed by weighing fine formulation materials. In the weighing method, the self-calibration module is used to perform the automatic calibration function to weigh the fine formulation materials. This provides a high degree of automation, and greatly reduced cost in equipment and labor for a formulating process, saving on time and labor, and with no risk of cross-contamination.

A dosing device for the continuous, gravimetric dosing of pourable material particularly rough fuels, wherein a flow of material Is conveyed from a charging opening to an emptying opening in a housing with a rotor which is driven about a vertical rotation axis, while determining the instantaneous load over a measuring section, and with a force measuring device which detects the instantaneous toad of the flow of material guided via the rotor comprising a plurality of ribs and a peripheral ring said ribs being attached to the peripheral ring, and said ribs defining a number of chambers inside the peripheral ring for carrying material during operation wherein an elastic peripheral sealing lip is arranged on the peripheral ring and engaging an upper housing wall such that an outer peripheral volume of the inside of the housing is sealed from a central volume of the housing.

An apparatus (1) for continuous gravimetric metering of pourable material comprises a housing (2) comprising a first and a second spaced wall (5,6), a charging port (7) through the first wall (5), and a discharging port (8) through the first wall (5) displaced from the charging port (7) and a primary air port (10) with a primary outlet opening (9) through the second wall (6) opposite to the discharging port (8). In the second wall (6) a secondary air port (12) is provided with a secondary outlet opening (11) having a substantially smaller outlet area than the primary outlet opening (9) and being displaced from the primary outlet opening in opposite direction to the rotational direction of the rotor (3) and being arranged opposite to the discharging port (8), and where the primary and secondary air ports (10,12) are connected to a compressed air supply.

Methods and systems for controlling a vibratory feeder are disclosed. In some embodiments, the methods and systems include the following: a controller module including a graphical user interface for selecting operating parameters to be communicated to a bowl drive that causes a feeder bowl to move, monitoring algorithms stored in non-transitory memory for processing motion data to monitor motion of the feeder bowl, and adjustment algorithms stored in non-transitory memory for determining and automatically adjusting the operating parameters, and a motion sensor module configured to mount with and sense motion of the bowl drive, the motion sensor module including an accelerometer, a digital signal processor (DSP) microcontroller, and a transmitter. The DSP microcontroller samples output data from the accelerometer, determines motion data of the motion of the bowl drive, and transmits the motion data via the transmitter to the controller module.
