The innovation relates to a device and a method for measuring a powder mass flow for powder cladding. Before the powder cladding, the powder mass flow is set by means of a powder mass determining device and a powder mass flow sensor is calibrated on the basis of the setting. Then a powder switch is used to begin the powder cladding without interrupting the delivery of the powder mass. During the powder cladding, the powder mass flow is monitored by means of the powder mass flow sensor.

A fluid flow testing apparatus for measuring the pour profile of a container has a rotatable container carrier and an assembly for rotating the container between a first position allowing fluid to be retained within the container and a second position causing fluid to be poured from the container. Sensors for sensing the weight of the container as liquid is poured from the container are provided in order to determine the pour profile of the container. A controller receives input signals from the sensors in order to record the weight of the container over time as liquid is poured from the container as the container is rotated. The change of weight of the container over time establishes a pour profile for the container.

A metering and/or weighing device includes a bulk material container with a bulk material inlet and a bulk material delivery. The latter is configured to deliver bulk material which is present in the bulk material container, in intervals in a metered and/or controlled manner. The metering and/or weighing device has a radar sensor which is attached to the container at the upper side and generates a beam cone which is directed downwards into an inside of the container, in order to determine a level of the bulk material which is present in the container.
