UNSC *1 = K factor x 1 = 1 pulse out/pulse in
UNSC*10 = K factor x 10 = 10 pulses out/pulse in
UNSC*100 = K factor x 100 = 100 pulses out/pulse in
C09: Unit Conv. Fa 0.00001 to 32000 C9 0.00001 to 32000 Use when custom flow units are needed.
Value = (std. span units/custom unit)
Refer to "How to set up for user defined flow units" for
details.
C10: Users Unit 8 characters No access Using the Alphanumeric keys enter the name of the
custom flow unit. Only the first 3 characters will be
displayed in Parameter: A20.
C60: Self-check Good
Error
Read only No access Diagnostic self-check. If good is displayed no error
exists. See “How To Use Diagnostics” for details.
D: Adjust Read only No access This signifies the beginning of the D Menu. This Menu
allows access to special compensation features.
D01: Reynolds Adj Not active
Active d1 0
1 This parameter is used to improved accuracy when
measuring flow between a Reynolds No. Of 5,000 and
20,000. Accurate viscosity and density values must be
provided. Refer to “How to activate Reynolds Number
correction” for details.
D02: Viscosity 0.00001 to 32000 d 2 0.00001 to 32000 Enter operating viscosity in centipoise, for use with
Reynolds number correction only.
D03: Density f 0.00001 to 32000 d 3 0.00001 to 32000 Enter operating density units per B07, for use with
Reynolds Number correction only.

6 This function corrects for errors that may be caused
when YEWFLO is installed in pipe other than Sch 40
Pipe. To invoke this function, select the connection
and pipe Sch from the list. Refer to “How to activate
Mis-matched pipe schedule correction” for details.
D06: Expansion FA Not active
Active d 6 0
1 This function improves gas accuracy above 35 m/s to
0.8% of rate, when metering a compressible fluid (Gas
or Steam). To activate this function, select ACTIVE.
Refer to “ How to increase gas and steam accuracy by
correcting for gas expansion” for details.
D20: Flow Adjust Not active
Active No access Select active to activate this linearization feature and
input the appropriate data in parameters D21 through
D30. The correction data for this function requires
special calibration. Call Factory for details.
