Honeywell expands its Zephyr airflow sensor HAF Series portfolio with digital versions that provide airflow ranges of 0 to 20l/m and 0 to 200l/m, leveraging the original Zephyr building block airflow sensor via a bypass to the main flow channel of the sensor, eliminating the need for a customer-designed bypass in equipment such as ventilators. The airflow sensors with the built-in bypass offer customers three important benefits.

High performance that includes a narrow Total Error Band (the most comprehensive and meaningful measurement that provides the sensor’s true accuracy) of ±4% reading and a high accuracy of ±3.5% reading, allowing for very precise airflow measurement-often ideal for demanding applications with high accuracy requirements.

Ease of integration provided by simple electrical interfaces (regulated, compensated, calibrated, linearized) and multiple mechanical configurations (manifold mount, male and female fittings).

Custom calibration, including forward flow direction and optimized custom calibration for many gases (dry air, helium, argon, nitrogen, nitrous oxide, carbon dioxide), which eliminates the need to implement gas correction factors.

These airflow sensors are designed to function in a wide range of applications. Potential industrial applications include air-to-fuel ratio, analytical instrumentation, fuel cells, fume hoods, gas leak detection, and gas meters.
