Method for the Gravimetric Control of a Metering Device for a Bulk Material During the Refilling of its Storage Container, and Metering Device for Carrying Out the Method
The method according to the invention provides a way to continue gravimetric weighing of bulk material during refilling of a gravimetric metered dispensing unit, and to determine the mass of the refilled bulk material using a refilling container during the filling operation material and so determine the actual mass flow discharged during refilling in real time or on average in order to adjust it to a target mass flow.
Batch weighing/supply device, and operating method therefor
In a batch weighing/supply device, a primary height adjustable scraper that reduces the quantity of conveyed raw material when lowered is provided on an upstream side of a discharge port in an annular passage, a secondary height adjustable scraper that further reduces the quantity of conveyed raw material, after the quantity has been reduced by lowering the primary height adjustable scraper, is provided on a downstream side of the primary height adjustable scraper, control means is provided to reduce the rotation speed of rotary blades to a first speed being lower than a normal speed, when the primary height adjustable scraper is lowered and reduce the rotation speed of the rotary blades to a second speed being lower than the first speed, when the secondary height adjustable scraper is lowered, and a sliding gate for opening and closing a raw material drop-down path is provided under the discharge port.

MONITORING ARRANGEMENT, AND A METHOD FOR INSTALLING SUCH A MONITORING ARRANGEMENT
The invention relates to a monitoring arrangement (1) for a reservoir (2) with a plurality of support members (21), the monitoring arrangement (1) comprising: at least one load cell module (3) with a base plate (31) for attachment to a support surface (100) and an elongated measuring device (37) attached to the base plate (31); and at least one adapter unit (4) configured to be attached to a support member (21) of the reservoir (2) and rest on the measuring device (37); wherein the base plate (31) of the at least one load cell module (3) comprises a recess (32) allowing the base plate (31) to at least partly surround the support member (21) circumferentially when installed, and the measuring device (37) is arranged on the base plate (31), such that it at least partly extends over the recess (32).
SYSTEM AND METHOD FOR MEASURING GRAIN CART WEIGHT
A system of detecting loading and unloading of mobile containers such as grain carts utilizes two low pass filters to determine whether the contents of the container are changing by subtracting one filter signal from the other, and using the sign of the difference. Weighing performance is improved by utilizing accelerometers to compensate for measurement dynamics and non-level orientation. Failure and degradation of weight sensors is detected by testing sensor half bridges. Loading and unloading weights can be tied to specific vehicles by utilizing RF beacons.

APPARATUS AND METHOD FOR WEIGHING PHARMACEUTICAL CONTAINERS NESTED IN A CARRIER
The invention relates to an apparatus and a method for weighing pharmaceutical containers (19) nested in a carrier (18), wherein the apparatus comprises at least one weighing device (22) and at least one receptacle (20) for the carrier (18) of the containers (19), wherein the receptacle (20) is connected to the weighing station (22) for weight detection.
Weighing apparatus that reduces power consumption during opening and closing of a hopper gate
[Problem] To provide a combination weighing apparatus that reduces power consumption during opening and closing operations of a hopper gate. [Solution] In a combination weighing apparatus 1, a control unit 70 controls a stepping motor 60 via a control signal that is input to the stepping motor 60. The control signal that is input to the stepping motor 60 is a voltage value corresponding to a desired current value. The control unit changes the control signal to the stepping motor 60 in conjunction with a change in the settings of the opening and closing speed of the gate 20. As a result, it becomes possible to supply power needed for the operation of the gate 20, and power can be saved.
METHODS AND APPARATUS FOR FEEDING, WEIGHING, AND COLLECTING SOLID FOOD PRODUCTS WITH STICKY COATINGS
A multihead weigher with a collector for feeding, weighing and collecting solid food products with a sticky coating. The multihead weigher has a number of receptacles for weighing the solid food products and discharging the solid food product to the collector. Each receptacle having a scraper for scraping the surface of the receptacle when the solid food product is being discharged from the receptacle into the collector.
Weight and flow rate measurement device and weight and flow rate measurement method
A flow rate measurement device improves the flow rate measurement accuracy without increasing the size of the metering tank. The flow rate measurement device includes a metering tank having a supply port at its upper portion and a discharge port at its lower portion, an on-off valve that opens and closes a flow channel inside the metering tank, a weight measurement unit that measures a weight of the metering tank, and flow rate computing unit that supplies powders and/or grains continuously from the supply port to the metering tank, computes a flow rate of the powders and/or grains multiple times in a temporally-overlapped state on the basis of the weight of the metering tank measured by the weight measurement unit in a state where the on-off valve is closed, and computes an average flow rate of the powders and/or grains on the basis of the flow rate computed multiple times.
