Measuring and controlling the air flow in the exhaust duct is critical for
proper operation of the oven. The procedure is simplified by taking one
reading at the center of the exhaust duct. This can be done automatically
using an Exhaust Controller or manually using either a hot-wire
anemometer or a pitot tube set-up.
The Exhaust Controller is an optional piece of equipment used with the
oven. Call your Nordson representative or distributor for more
information.
To measure the exhaust duct air flow using an incline manometer,
perform the following steps:
NOTE: This procedure assumes the use of a pitot tube, rubber or plastic
tubing, and a inclined manometer. The manometer reads air flow in
either millimeters (inches) of water or velocity in meter per minute (feet
per minute).
