The Series SFI-800 Sight Flow Indicator provides protection for
expensive equipment and systems, accommodating fluid temperatures
as high as 212°F (100°C) and pressures up to 150 psi (10.34 bar). This
sight flow indicator is composed entirely of FDA/NSF-ratable materials.
It is exceptionally corrosion-resistant and can handle de-ionized water
and many acids, bases and salts. (Consult B. P. Amoco’s Extensive
“Chemical Guide” for further information on the Udel P1700 Polysulfone
resin).

The Series SFI-801 Sight Flow Indicator is similar to the SFI-800
except it is made of UV stablized materials. It can be used in outdoor
applications where indication of water flow or control is needed. The
materials are not FDA approved.

Three output options are available for the SFI-800 and 801:

The A-711 is a unique, patent pending sensor that outputs two pulse
voltage signals proportional to flow rate. Pulse outputs are a 5 VDC
pulse and a pulse of the input supply voltage used, which can be 8 to 28
VDC. This sensor can be used to monitor flow rate and flow totalization.

The A-712 is a sensor that outputs a linear 1 to 10 VDC signal propor-
tional to flow rate. This sensor can be used to monitor flow rate.

The A-713 is a flow switch with open collector outputs. One output is
active above setpoint and the other output is active below setpoint. The
setpoint can be changed by pressing a button at the desired flow rate.
