FLR1000 Series flow sensors can measure extremely
low flow rates from 20 mL/min to 5 L/min. These
sensors are suitable for a wide variety of industrial,
commercial, and laboratory flow applications.
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
flowmeters 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.

For liquid flow metering with integrated rate display,
the FLR1000ST-D Series has been setting the pace.
Their advanced Pelton-turbine design provides
high turndown ratios, fast response, and repeatable
accuracy. A 0 to 5 Vdc analog output is standard.
Featuring a 31⁄2-digit display of flow rate in engineering
units, these flowmeters are perfect for any laboratory
or test facility. For higher-pressure applications or
where metal may be required, the FLR1000ST Series
is the solution, see page F-89 for complete details.
