Flow indicator with rotor<br />
up to 16 bar. The instruments can<br />
be used for temperatures up to<br />
110 °C (polysulfone) or up to 60 °C<br />
(Trogamid-T).<br />
The special connection<br />
supports enable optimum turning<br />
of the sight glass of this indicating<br />
unit for an optimum view even<br />

The rotating vane flow indicator<br />
model DAF is for application<br />
where visual flow indication<br />
without flow measurement is<br />
required.<br />
A square housing with<br />
transparent front and back<br />
windows contains a rotating vane<br />
whose rotary motion, caused by<br />
the flowing medium, indicates<br />
presence of "flow”.<br />
The DAF series may be installed<br />
in pipes from G 1/8 to G 1 ½ with the<br />
same housing. Further versions are<br />
available with flange connection<br />
from DN 15 to DN 50. Flow ranges<br />
from 0.03…0.1 to 5…150 l/min can<br />
be obtained by changing the inlet<br />
port orifice.<br />
The instruments can be<br />
installed in any position. Flow,<br />
however, must be in the direction<br />
indicated by the arrow.<br />
Four different material<br />
combinations allow an optimum<br />
instrument selection for a<br />
multitude of applications.<br />
A housing made of complete<br />
plastic (Trogamid-T or polysulfone<br />
with stainless steel connections<br />
for aggressive media) provide a<br />
cost-effective flow indicator for<br />
pressures up to 10 bar.<br />
The flow indicator DAF can<br />
also be supplied with a brass<br />
housing with Trogamid-T cover<br />
(or stainless steel housing with<br />
polysulfone cover) for pressures
