HAF Series-High Accuracy
±50 SCCM to ±750 SCCM Benefits:
Total Error Band (TEB) as low
as ±0.25 %FSS allows for precise airflow
measurement, often ideal for demanding
applications with high accuracy
requirements. Fast response time allows
a customer’s application to respond
quickly to airflow change, important in
critical medical (e.g., anesthesia) and
industrial (e.g., fume hood) applications.
Measures mass flow at standard flow
ranges of ±50, ±100, ±200, ±400 or
±750 SCCM, or custom flow ranges,
increasing the options for integrating the
sensor into the application.
Customizable
flow ranges and configurable package
styles meet specific end-user needs. Full
calibration and temperature compensation
typically allow customer to remove
additional components associated
with signal conditioning from the PCB,
reducing PCB size as well as costs often
associated with those components (e.g.,
acquisition, inventory, assembly).
High
sensitivity at very low flows provides
for faster response time at the onset or
cessation of flow. Linear output provides
a more intuitive sensor signal than the
raw output of basic airflow sensors,
which can help reduce production costs,
design, and implementation time. High
reduces noise and system wear on
stability reduces errors due to thermal
effects and null shift to provide accurate
readings over time, often eliminating
need for system calibration after PCB
mount and periodically over time. Low
pressure drop typically improves patient
comfort in medical applications, and
other components such as motors and
pumps. High 12-bit resolution (digital)
increases ability to sense small airflow
changes, allowing customers to more
precisely control their application; 0.039
%FS resolution (analog) increases
ability to sense small airflow changes,
allowing customers to more precisely
control their application. Low 3.3 Vdc
operating voltage option and low power
consumption allow for use in battery driven
and other portable applications.
ASIC-based I2C
digital output compatibility
eases integration to microprocessors or
microcontrollers, reducing PCB complexity
and component count. Insensitivity to
mounting orientation allows customer
to position the sensor in most optimal
point in the system, eliminating concern
for positional effects. Insensitivity to
altitude eliminates customer-implemented
altitude adjustments in the system,
easing integration and reducing
production costs by not having to
purchase additional sensors for altitude
adjustments. Small size occupies less
space on PCB, allowing easier fit and
potentially reducing production costs;
PCB size may also be reduced for easier
fit into space-constrained applications.
Designed for use in medical equipment
such as anesthesia delivery machines,
ventricular assist devices (heart pumps),
hospital diagnostics (spectrometry, gas
chromatography), nebulizers, oxygen
concentrators, sleep apnea machines,
spirometers, ventilators, and laparoscopy,
as well as industrial air to fuel ratio,
analytical instrumentation (spectrometry,
chromatography), fuel cells, gas leak
detection, VAV system on HVAC systems,
gas meters, and HVAC filters.

10 SLPM to 300 SLPM Benefits:
Industry’s smallest Total Error
Band (TEB) allows for precise airflow

application to respond quickly to airflow
change, important in critical medical
and industrial applications. High stability
reduces errors due to thermal effects and

Choice of port styles provide flexibility to
choose the pneumatic connection that is
best for the customer’s application.
Linear
output provides a more intuitive sensor
signal than the raw output of basic airflow
sensors, which can help reduce
production costs, design, and
implementation time. Wide supply voltage
range gives the designer the flexibility to
choose the supply voltage that works best
in the system. ASIC-based I2C digital
output simplifies integration to
