Rotating Vane Flow Indicator DAF-2
Indicating range: 0.03 - 0.1 ... 5 - 150 l/min water
Connection: flange DN15 ... DN50, ½ ... 2" ANSI
Material: stainless steel
pmax: 16 bar
Application and Operating Principle
The KOBOLD Rotating Vane Flow Indicator is applied where visual flow indication without flow measurement is required. A square housing with transparent windows front and back, contains a rotating vane whose rotary motion, caused by the flowing medium, indicates presence of “flow”.
Within the same housing dimensions, differing minimum and maximum flow ranges are obtained by changing the inlet port orifice. The instruments can be installed in any position. Flow, however, must be in the direction indicated by the arrow.
Connection is made by means of stainless steel flanges in accordance with DIN/Form C in standard sizes DN 15, 25, 40 or 50.
