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 household appliance includes the food preparation container, into which an ingredient for food preparation can be fed by the user. The household appliance includes at least one sensor for determining a feeding quantity of an ingredient as the ingredient is being fed into the food preparation container. A control device of the household appliance is configured to determine the feeding quantity based on a sensor signal of the at least one sensor such that a user can prepare particularly reliably and reproducibly a food that requires a uniform feed of an ingredient for a predetermined period of time.

Analysis system (310) for a powder jet of an additive manufacturing machine, said powder jet (21) comprising powder and gas, said analysis system (310) comprising a separation device (312), said separation device (312) comprising: —a separator element (326, 327) comprising a circular side wall (328) defining a cylinder and at least one separation wall (330) suitable for separating the inner volume of said separator element (326, 327) into n equal portions that are symmetric with respect to the axis of symmetry of the cylinder, said separator element (326, 327) being suitable for receiving an initial powder jet (21) at the centre of said separator element (326, 327), on said at least one separation wall (330), in order to separate the initial powder jet (21) into n powder jet portions; and —means for detecting the quantity of powder in each powder jet portion.

A valve of a first container is opened to remove fluid into a second container, where the output of the first container is above a maximum fluid level of the second container. The valve of the first container is closed based on a sensor indicating that a fluid level in the first container is at a first fluid level. A pump pumps the fluid from the second container to the first container via a flow meter. An indication is received that causes the pump to stop pumping based on the indication. An amount of fluid pumped into the first container is determined based on the first fluid level and a second fluid level indicated by the sensor. An indication of total fluid volume measured by the flow meter is compared to the amount of fluid pumped. An indication of accuracy of the flow meter is output based on the comparison.

A method for calibrating flow meters for fluid media comprises the steps of guiding a medium (102) through a reference measuring section (101-1) and a test measuring section (101-2) which has a flow meter to be calibrated, establishing at least approximately identical and constant pressure and flow conditions for the medium (102) in both measuring sections (101-1, 101-2), detecting a reference throughflow of the medium (102) through the reference measuring section (101-1) and throughflow values which correspond temporally thereto and are measured by the flow meter (125) to be calibrated of the test measuring section at a preset medium temperature, comparing the detected reference throughflow through the reference measuring section (101-1) with the throughflow values which correspond temporally thereto of the flow meter (125) to be calibrated, in order, based on this, to determine at least one correction value for the calibration of the flow meter (125) at the preset medium temperature, and determining of the respective correction value for the flow meter (125) for different medium temperatures of the medium (102), in order to determine a calibrating function using the temperature-dependent correction values as grid points.

System and methods for calibrating a coating system are disclosed. Initially, a material is dispensed using an applicator of the coating system for a predetermined time period. A characteristic of the dispensing of the material for the predetermined time period is then determined. The characteristic of the dispensing of the material is compared to a predetermined range and it is determined that the characteristic of the dispensing of the material is outside of the predetermined range. In response, a velocity of the applicator, a pulse rate of the applicator, a temperature of the material, a pressure of the material supplied to the applicator, or a fan width of the applicator is adjusted to change the characteristic of the dispensing of the material.
