The HDO 500 is a flow meter for non-flammable liquids, such as many alkalis and acids, paints, cosmetic products, lacquers, mineral oil, etc. It is available in two types, which include stainless steel for aggressive and neutral liquids, and aluminum for neutral liquids.

The operating menu and display support multiple languages. As for flow rates, the HDO 500 is suited for a range from 15l/min – 360l/min. Its design allows for a high amount of accuracy, low friction losses and support for thin-bodied liquids.
