HK Instruments DPT-Flow-Batt Series Installation Instructions

INTRODUCTION
Thank you for choosing an HK Instruments DPT-Flow-Batt series
air flow meter. The DPT-Flow-Batt series is intended for use in en-
vironments and applications where electricity is not available. The
DPT-Flow-Batt measures air flow, velocity and differential pressure.
It is designed to be used in combination with centrifugal fans that
provide differential pressure connections and K-values.
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
