FLR1000 Series flow sensors can measure extremely
low flow rates from 20 mL/min to 500 L/min. These
sensors are suitable for a wide variety of industrial,
commercial, and laboratory flow applications. Not for use with Hydrogen or Helium.
FLR1000 Series flow sensors operate on 12 Vdc
power and are designed for incorporation into data
acquisition systems that supply 12.5 Vdc to sensors
and receive 0 to 5 Vdc linear signals in return.
Because of their cost effectiveness, FLR1000 Series
units may replace conventional glass tube and ball
flow meters in applications in which an electrical signal
proportional to flow rate is desired.
The FLR1000 Series uses a Pelton-type turbine wheel
to determine the flow rate of the gas. The rotation rate
of the turbine wheel is linear over a wide dynamic
range. The electro-optical system consists of a diode
emitting energy in the infrared spectrum. Light energy
is alternatively reflected and absorbed from "spokes"
deposited on the small turbine wheel. This reflected
light energy is detected by a photodiode. Thus, as the
turbine wheel rotates in response to gas flow rate,
electrical pulses are generated. Processing circuitry
provides a DC voltage output proportional to the flow
rate. For example, output signal is 1.0 Vdc at 20% of
rated flow, 2.5 Vdc at 50% of rated flow, 4.0 Vdc at
80% of rated flow, and 5.0 Vdc at 100% of rated flow.
Sensors can handle 20% above their rated flow
without being damaged.
