The flap indicates flow on an easy to read scale. It is for use with liquids or steam. It is particularly suited for full bore flows or applications with low flow as the flow must move the flap to pass through the meter. It is ideal as a plant safety device where you need to maintain a constant flow, for example in lubricating or cooling systems. Suitable for horizontal or vertically upward flow.


The flap flow indicator is ideal for full bore applications especially those were a higher precision is required and can be achieve using the unit scale. It can be use for liquids or steam Double scaled windows give a visual indication of the presence, colour and condition of flow in any process line.
