DAF-1 Rotating Vane Flow Indicator

Brand: KOBOLD Instruments, Inc.

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.

They are pivot-mounted, which enables the sight glass of the indicating unit to be turned to an optimum viewing direction even during operation (not with material combination DAF-14).
