The EF-X1000-T (ELF) (EB-Flow II) Series 1000 is EBTRON’s economical airflow/temperature measurement solution for round ducts between 4 and 16 inches in diameter. The EV-X1000-T is ideal for small duct airflow measurement and volumetric airflow tracking applications. Low flow performance, temperature capability, and connectivity options make this a better choice than traditional differential pressure averaging arrays, rings, and crosses.
