Product Application The Air Measuring Station (AMS) is designed to be used in any application that requires accurate airflow measurement at velocities between 300 and 5,000 feet per minute (1.5 and 25 m/s). Unit may be installed in the duct or in an air handling unit and can be used to measure outside air, return air, discharge air or exhaust air flows into or out of a building or air handling unit.

Remove the AMS from its shipping container and inspect for damage, rust or corrosion. Care must be taken in NOTE: Pressure transducer may be removed and relocated during handling the unit. Always handle the AMS by its frame. Do not drop, drag, step on or apply excessive bending, installation. Orientation is critical. Refer to Installation Instructions.

Disconnect the sensing tubes between the damper and the pressure transducer. Apply a clean pressurized air source, less than 10 PSI, to the air piping connections at the AMS frame in order to blow out any condensation or dirt accumulation plugging the sensing ports. Do noT connect this air source to the pressure transducer.
