As long this « Auto Zero” message is displayed, the UF 801-P is in progress and
acquires this “Delta To” offset. When finished, it automatically places this value
at” Delta_To” line.
Attention ! This value is tight to actual measurement point. As an approximate, it
can be considered as attached to a same probes set, but, if the next application is
very different, please reset it to zero in probes menu.
Q. Cut Off
t
. :
Another possibility in normal and advanced modes : entering of a
low threshold to force a Zero Flow display below the set value.
Attention! This does not mean that you have adjusted the zero. You just have
forced it to zero as long it stays below the set value. Totalizers will not be ordered
and current output flow copy will stay at range bottom (0 or 4 mA).

Additional Parameters in Advanced mode:
Exact Settings on a multilayer pipe :
------- PIPE -------
--------Tube--------
Ext.Diam. = ******mm
Ext.Circ. = ******mm
--------Wall--------
Material 1= xxxxxxx
Thick.1 = ***.**mm
Material 2= xxxxxxx
Thick.2 = ***.**mm
Material 3= xxxxxxx
Thick.3 = ***.**mm
Sp. Sound = I Other
In the other modes, you can
simply enter the whole thickness
and a material Speed of Sound
(CM) that averages the diverse
materials from their %.
Here, this setting is much
more accurate.
If there is only two materials, set
NONE at material 3
Turbulent to Laminar transition range:
------- PIPE -------
--------Fluid ------
Product = OTHER
Co = 1250 m/s
Delta C = 300 m/s
KH mode = AUTO/MAN
Viscosity= 2.5 CSt
Roughness= 0.15 mm
Reyn.Crit= 2800
LBR = 3.000
----Calibration----
CutOff Q = 5.00 l/s
AutoZero = No / Yes
In the other modes, the UF 801-P
manages this transition. The
typical entered values (Critical
Reynolds=2800 / LBR=3) offer
good results on viscous fluids as
hydraulic oil on pipes in the range
3/8” ~ 2”.
Here, you can adapt these settings
to your fluid and your installation
by adjusting this Reynolds Critic
and the transition range with LBR.
