HK Instruments DPT-Flow-Batt, an intuitive on-site display tailored for environments where electricity is inaccessible. This versatile device is compatible with various fan types and serves as a convenient tool for measuring airflow in duct systems, especially when paired with a FloXact averaging measurement probe.

Usage

HK Instruments DPT-Flow-Batt is specifically engineered for air handling units, enabling precise airflow measurement for centrifugal fans. Additionally, it seamlessly integrates into duct systems, functioning as an on-site display for flow measurement. It supports a range of measurement probes, including FloXactTM and pitot tubes, as well as air dampers, provided the K-value is known.

Applications

HK Instruments DPT-Flow-Batt series devices are commonly used in HVAC/R systems for:

  • Air flow monitoring across centrifugal fans and blowers
  • In-duct air flow monitoring
