FLOW
The VENTURI LF MAX FLOW item sets the flow rate
through the venturi valve when it is fully open. The display
will indicate a volumetric flow rate. Adjust the displayed
value to match the flow through the venturi valve.
NOTE: The flow information can be obtained from the
label on the TSI Venturi Valve or by opening the
venturi valve using the CONTROL OUT item in
the DIAGNOSTICS menu and performing a pitot
tube traverse of the duct.
The VENTURI LF MIN FLOW menu item must be
completed before moving on to the VENTURI LF MAX
FLOW menu item.

FLOW K FACTOR
FHM10 and FHC50
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.
