Airflow Measuring Station
steel airfoil blade–pressure differential
AM-45-PD airflow measuring stations employ a low leakage control damper with highly accurate airflow measuring equipment in a single compact assembly. The C&S AC-45 control damper is factory mounted with a modulating 24V actuator, multi-point self-averaging pressure sensing probes, and VELTRON DPT 2500-plus transmitter to provide airflow measuring along with the ability to control airflow all in one easy to install assembly.
