Flap Flow indicator Technical Datasheet arkon Y ^ flow systems This Flap flow indicator is ideal for you to visually check the flow, presence, colour and condition of a liquid This style is particularly suited to full bore flows, giving an indication of flow rate against a unit scale. Suitable for horizontal or vertically upward flow. Ideal as a plant safety device where it is required to maintain a constant flow, such as lubricating or cooling systems. For ease maintenance the glasses can be individually removed and replaced. For dirty or coloured liquids one window can be replaced with a steel cover and external pointer. For high flow rates and vertical lines the flap can be spring loaded. This option will give three times the normal flow range.
