The Series
SFI-800 Sight Flow Indicator is a low cost, durable
rotor style flow indicator with optional output sensor.
Constructed of clear Polysulfone, enabling 360° viewing
of the rotor, the SFI-800 has excellent pressure ratings,
temperature ratings, and chemical compatibility.
The
Series SFI-801 Sight Flow Indicator is similar
to the SFI-800 except it is made of UV stabilized materials.
It can be used in outdoor applications whre indication of
flow or control is needed. The materials are not FDA approved.
The SFI-801 also features an easily viewed bright red impeller.
The optional A-711
output sensor has a VDC output with pulsing for flow rate
totalization and a proportional frequency change for flow
rate. For added versatility there are two output choices
of 5 VDC or a VDC equal to the input power supplied. The
output is compatible with digital rate meters/totalizers
and other electronic systems. The Series SFI-800 is compact,
panel mountable and the A-711 output sensor package can
be ordered factory assembled or can be easily installed
on an existing unit in the field.
