Series SFI-800 Sight Flow Indicator/Transmitter |
| Low Cost, Optional Output for Flow Rate and Totalization
|
| |
 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 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 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. |
