The DAF paddle wheel provides visual flow indication without flow measurement. The simple design is a rectangular housing with two transparent windows containing a paddle wheel, which is set into motion by the flowing media. The clearly visible, rotating paddle wheel provides visual indication of flow. Flow ranges are varied by changing the inlet port orifice, allowing use of the same size housing for all flow ranges. The flow indicator can be installed in any position, as long as the flow remains in the direction of the arrow on the housing. Connections are available in 1/8” NPT through 1-1/2" NPT, with a wide choice of materials for media compatibility. The DAF flow indicator may be rotated along its long axis, even during operation, due to the rotatable fittings.
