Flow Indicator with Rotor

The KOBOLD Rotating Vane Flow Indicator model DAF is applied where visual flow indication without flow measurement is required. A square housing with transparent front and back windows contains a rotating vane whose rotary motion, caused by the flowing medium, indicates presence of “flow”.

The DAF series may be installed in pipes from G 1/8 to G 1 ½ with the same housing. Further versions are available with flange connection from DN 15 to DN 50. Flow ranges from 0.03…0.1 to 5…150 l/min can be 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. Four different material combinations allow an optimum instrument selection for a multitude of applications.

A housing made of complete plastic (Trogamid-T or polysulfone with stainless steel connections for aggressive media) provide a cost-effective flow indicator for pressures up to 10 bar. The flow indicator DAF can also be supplied with a brass housing with Trogamid-T cover (or stainless steel housing with polysulfone cover) for pressures up to 16 bar. The instruments can be used for temperatures up to 110 °C (polysulfone) or up to 60 °C (Trogamid-T).

The special connection supports enable optimum turning of the sight glass of this indicating unit for an optimum view even during operation.
