HK Instruments DPT-Flow-1000 Installation Instructions And Owner's Manual

INTRODUCTION
Thank you for choosing an HK Instruments DPT-Flow series air
flow transmitter. The DPT-Flow series is intended for use in com-
mercial environments. The DPT-Flow measures air flow, velocity
and differential pressure. It is designed to be used in combination
with air flow measurement probes (i.e. FloXact) or with centrifugal
fans that provide differential pressure connections and K-values.
The DPT-Flow series of air flow transmitters is comprised of DPT-
Flow-1000, DPT-Flow-2000, DPT-Flow-5000 and DPT-Flow-7000
with measurement ranges of 0–1000 Pa, 0–2000 Pa, 0–5000 Pa
and 0–7000 Pa respectively. All models come with display and
manual pushbutton autozero. The DPT-Flow is available with op-
tional autozero calibration.
APPLICATIONS
DPT-Flow series devices are commonly used in HVAC/R systems
for:
• air flow monitoring across centrifugal fans and blowers
• in-duct air flow monitoring
• VAV applications
