New! Fluke 922 Airflow Meter
Today’s HVAC technicians want a simple
solution for diagnosing ventilation issues. The
Fluke 922 makes airflow measurements easy
by combining pressure, air flow, and velocity
into a single, rugged meter.
Use the Fluke 922 to:
•
Ensure proper air flow balance
•
Monitor pressure to extend HVAC
component life
•
Promote good indoor air quality
•
Maintain a comfortable environment
Features include:
•
Powerful meter provides differential and
static pressure, air velocity and flow
readings
•
Rugged case and holster for real-world use
•
Easy to use without sacrificing performance
•
User-defined duct shape and size for maxi-
mum utility
•
Convenient colored hoses helps users prop-
erly diagnose pressure readings
•
Bright, backlit display for less than ideal
environments
•
Min/Max/Average/Hold functions for easy
data analysis
•
Auto power off saves battery life
Quick Tips
How HVAC airflow impacts
operating costs
Dirty coils, fans, and filters
will increase static pressure
by reducing airflow, caus-
ing HVAC equipment to work
harder to meet occupant loads
and increasing energy costs.
With HVAC energy costs often
comprising over 50 % of
the total energy bill, tighter
monitoring and control of
HVAC airflow can have a direct
impact on the bottom line.
•
In a study
1
on coil clean-
ing and energy savings in
a New York City high rise,
pressure monitoring and
visual inspection led to
restoration of the coils and
components. The restora-
tion resulted in a 14 %
decrease in pressure drop
across the coils, a 25 %
increase in the coil’s ther-
mal efficiency, and energy
savings of up to $40,000 in
the first year.
•
EPA studies
2
show that a 15
cfm airflow differential can
impact annual HVAC energy
costs by up to 8 % depend-
ing upon the HVAC system
and variations in climate.
