Accurate and Reliable Pressure, Velocity and Flow Meter
with Auto-Zero
The FKS 1DP-PBM and FKS 1DP-PBM-E are feature-rich, state-of-the-art multi-function meters designed for fast and accurate
pressure, velocity and flow measurement. The meters have unmatched ease of use due to their prompt driven user interface
and intuitive operation. They are the perfect companions for Testing and Balancing, HVAC, Process Monitoring, R&D, velocity
traverses, stack velocity measurement, pressure measurements across fans, filters, etc.
Benefits
Both Models
NIST certificate with data.
Measure true differential (+ and -), static and gauge pressure.
Fast electronic zero.
Actual and standard velocity (using a Pitot or S type probe).
Velocity measurements in dirty airstreams using an S probe.
Adaptive damping: Sophisticated damping technology
automatically adjusts the damping level (the running average
constant, or number of averages) to give you the best
measurement for your conditions. Very useful in unsteady flows.
Additional Benefits of the FKS 1DP-PBM
Auto-zero function. Internal valve removes pressure or velocity
offsets. Your reference level never changes, ensuring
unmatched accuracy and reliability. You can even set the auto-
zero time interval!
Data logging: Both manual and automatic logging available.
Store up to 10,000 pressure, velocity and flow readings in up to
520 separate groups. On-screen recall shows average, max and
min. Automatic logging lets you take unattended readings with
log times from seconds to days. Simply tell the meter how long
to acquire data for, and the interval between readings! The auto-
zero feature ensures accuracy, even after hours or days of
logging. Included downloading software transfers your data
directly into Microsoft Excel.
Air flow mode: An inbuilt volumetric flow survey routine prompts
the user to set duct shape, number of readings and duct size
allowing for the calculation of accurate air flows (you don’t have
to use inaccurate single point measurements any longer –
although the PBM will do these too!) incredibly easily and
quickly. The meter guides you through the survey point by point.
Confidence interval estimation: A sophisticated statistical routine
calculates the confidence interval of your pressure, velocity and
flow measurements, giving you unmatched confidence in your
readings.
Overload protection: Pressure overloads cause the meter to
automatically enter the auto-zero cycle, reducing the potential for
transducer damage.
