Optional VFD Velocity Meter tubing
(required for VFD operation)
The velocity meter requires a special section of hard pipe, with a tapped fitting location for
the velocity meter installation. The compression fitting allows the velocity sensor to be ori-
ented such that the hole (noted by a mark on the sensor) can be positioned to face the air-
flow, and adjusted such that the depth of sensor hole is located in the center of the air flow
in the piping.
The section of tubing with the velocity meter tap should be located about 10x the tube diam-
eter (80 inches for 8-inch tubing) of straight pipe (after a bend) on the return line before the
dryer. Due to velocity meter cable length and tubing runs, the best location is typically as
close to the “Return air” inlet of the dryer on the return air tubing as possible. This typically
gives the maximum straight run of tubing prior to the velocity meter location.
