VENTURI PT6
The VENTURI PT6 item is used to calibrate a venturi valve
without feedback. When this item is entered, the display will
indicate a volumetric flow rate. Adjust the displayed value to
match the flow through the venturi valve when the venturi
valve is at the 100% OPEN position.
0 to 10000 cfm
0 cfm
NOTE: The flow information can be obtained through a
direct flow measurement (i.e., duct traverse) after
using the CONTROL OUT item to set the damper
to 100% Open or from the label on the TSI Venturi
Valve.
FLOW K FACTOR
FHC50 Only
FLOW
KFACTOR
The K FACTOR menu item sets the “K” factor for the flow
signal. The flow signal is multiplied by the K FACTOR so
that the flow measurement matches the actual flow,
determined with a pitot tube traverse.
NOTE: FLOW K FACTOR modifies the entire range of
the calibrated flow, not just a single point.
