Description
Apparatus for determination of flow rate, Hall Flowmeter according to DIN EN ISO 4490, is a calibrated laboratory instrument for measuring how free-flowing metallic powders and hard-metal powders pass a standardised funnel. The method records the time needed for 50 g of powder to flow through the calibrated outlet opening. The system is frequently applied in additive manufacturing (3D printing) for incoming inspection and routine control of powder raw materials. Built from non-magnetic stainless steel V4A (1.4305), the apparatus is electropolished, with a high-gloss polished funnel surface that supports reproducible flow measurements. The supplied set comprises a stainless-steel test funnel, a funnel nozzle with calibrated outlet, a stainless-steel stand with holding arm, operating instructions and a sample test protocol. Measurement practice follows DIN EN ISO 4490 (Hall Flowmeter) and aligns with ASTM B213-13 for metal-powder flow rate. Offered by manufacturer Landgraf HLL, the apparatus is intended for laboratories equipped with a precision balance (±0,01 g) and a universal drying oven. Optional accessories such as a stainless-steel dish, factory calibration certificate for the nozzle, timer, Chinese emery grain and a collection tray further support calibration and daily use.

Questions about Apparatus for determining the flow rate, Hall flowmeter according to
What is this article?
Apparatus for determining the flow rate, Hall flowmeter according to is the article on this page. Luminix Health distributes Landgraf HLL for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
