FPR1501 Series flow sensors can
measure extremely low flow rates
from 15 mL/min. They are suitable
for a wide variety of industrial,
commercial, and laboratory flow
applications.
Because the FPR1501 flow sensors
have only PTFE and sapphire
wetted surfaces, it is anticipated that
they will replace conventional glass
tube and ball flowmeters in many
applications in which an electrical
signal proportional to flow rate is
desirable, even in very corrosive
applications in which the liquid is
low in viscosity (i.e., less than
10 centistokes).
Models use a Pelton-type turbine
wheel to determine the flow rate of
the liquid. The rotation rate of the
turbine wheel is linear over a large
dynamic range. The electro-optical
system consists of a diode emitting
energy in the infrared spectrum. Light
energy is interrupted and passed
from 8 small holes in the small
turbine wheel. This reflected light
energy is detected by a photodiode.
Thus, as the turbine wheel rotates
in response to the liquid flow rate,
electrical pulses are generated.
Processing circuitry provides a
DC voltage output and buffered
square-wave output pulses that are
proportional to the flow rate.
