Multi-Point Measurement of HVAC Duct Airflow

Multipoint Measurement HVAC Duct Airflow 
HVAC Series "Analyzing Airflow" Part 2:  

Note: Part 3 of our HVAC Series – Analyzing Airflow discusses available configuration options from Degree Controls and describes our embedded platform solution for a large duct application. 

The °C SPAR Sensor Pole Array from Degree Controls is optimal for in-duct HVAC airflow analysis. It is a linear array of airflow sensors assembled into a single tube element with USB outputs. The °C SPAR is designed for multipoint experimentation where there are predefined measurement locations, just as shown in the Log-Tchebycheff Rule for calculating volumetric flow within ducts. With the °C SPAR, air velocity, temperature, and humidity can be measured and recorded at multiple points in real-time for building duct performance testing.

Multi-Point Airflow Measurement with ANSI/ASHRAE Standard for Traversing a Duct

The °C SPAR is built to client specified dimensions, including tube length, sensor quantity, pitch, and calibration range. °C SPARs reduce set-up time by eliminating complex fixturing that goes along with making multiple measurements across a plane, and °C SPARs increase test repeatability. Very little impedance is imparted to the air-flow profile.
