AS-300A Hall Flowmeter has been designed based on the funnel method principle to automatically measure the flow rate of powders. While the AIMSIZER Powder Comprehensive Characteristics Tester is used to characterize up to 15 physical properties, AS-300A is used to calculate the time taken by the powder to flow through the funnel. It has sensors, a testing platform, a Hall funnel, a laser, a Carney funnel (optional), certified reference material calibration powder (optional), a Gustavson funnel (optional), a touch-screen-controlled analysis system, a bulk density cup, and a printer.
Its automatic stop feature minimizes human error and reduces manual oversight. It also has the feature of automatic calibration, correlation, and adjustment. Its density cup volumes and funnel sizes meet international standards and are calibrated for accuracy. It also has optional unlimited data storage and export capabilities. The equipment adheres to international standards such as ASTM B212, MPIF No.4 Std. 04, ASTM B213, ISO 4490, MPIF No.3, and ISO No. 3923-1.

Around 50 g of metal powder is used to test its flow time through a standardized funnel. The funnel adheres to international standards, and the aperture has been calibrated. The test automatically begins when the powder starts to leave the funnel and blocks the laser on the testing platform. This triggers the sensor to start detection. The control analysis system records the time to flow cessation, as detected by the sensor. This is the test's flow time.
The test is repeated three times, and the resulting flow times, along with average results, are automatically calculated. The displayed data can be saved, printed, and exported.
