摘要： A measuring apparatus for measuring a coating powder mass flow rate generable by compressed gas in a powder line includes a control and evaluation unit, which is configured and operable such that it can switch between an offset mode and an operating mode. In the offset mode, the control and evaluation unit ensures that a setting device applies compressed gas to the powder line and prevents the coating powder flow in the powder line, and that a pressure sensor then detects the pressure in the powder line. The control and evaluation unit interprets the detected pressure as an offset pressure value. In the operating mode, the control and evaluation unit ensures that the setting device enables the coating powder flow in the powder line, and then determines the coating powder mass flow rate flowing through the powder line on the basis of the pressure detected by the pressure sensor in the powder line, the offset pressure value and a correction value.

摘要： A device and method of measuring and controlling the flow rate of a fluid determine analog process variables which are dependent on a volumetric flow of the fluid, and the values thus obtained are converted into digital values, the latter being corrected by an offset value which is dependent on a change of the operating parameters of analog components of the measuring system occurring in the course of operation of the system. To obtain the offset value, an analog process variable is determined during interruptions in operation, when the volumetric flow is zero, and converted into a digital value. This digital value is memorized and used as the offset value when operations are resumed. The digital corrected measured values are supplied to a digital signal processor and the flow rate control is carried out digitally. Preferably, at least one parameter memory is provided for the digital control.

摘要： A powder injector creates a powder-air mixture and feeds the mixture to a powder coating gun. The injector comprises a powder suction conduit, an injector nozzle fitted in the powder suction conduit, a mixing cone with a venturi tube connected thereto, the mixing cone being disposed downstream of the injector nozzle, a conveying air supply conduit including a control valve for feeding conveying air to the injector nozzle, and a metering air supply conduit for feeding metering air to metering air outlet ports opening into the venturi tube. The metering air supply conduit is composed of two parallel branch passageways branching off the conveying air supply conduit and opening into a common supply conduit leading to the metering air outlet ports. One of the two branch passageways has a metering air control valve disposed therein which is actuated by the air pressure prevailing in the conveying air supply conduit.
