Use the
Setup > Pipe
page to manually enter pipe parameters . If you used the lookup function in
Setup > ANSI Pipe
, nominal
values for
Pipe OD
,
Pipe Wall [Thickness]
and
Roughness
are automatically entered . If the actual values of the pipe differ from
the ones automatically entered, go back to
Setup > ANSI Pipe
and select
Manual Dimension Entry
to enter non-standard
parameters . Selecting
Manual Dimension Entry
unlocks the
Pipe Material
,
Pipe OD
and
Pipe Wall [Thickness]
inputs as shown in
Figure 54: Pipe page allowing manual entry
Pipe Material
When a pipe material is chosen from the Pipe Material list, a nominal value for speed of sound in that material and the pipe
roughness are automatically loaded .
Pipe OD (Numeric Value)
Enter the Pipe OD (outside diameter) in inches for English units or in millimeters for Metric units .
OTEE:
N
Charts listing popular pipe sizes have been included in this manual . Correct entries for pipe O .D . and pipe wall
thickness are critical to obtaining accurate flow measurement readings .
Pipe Wall [Thickness] (Numeric Value)
The Pipe Wall thickness is the value of the actual pipe wall thickness excluding any liner that may be present .
OTEE:
N
Accurate values for Pipe OD and Pipe Wall thickness are necessary for accurate computation of the volumetric flow
rate . Without accurate pipe data, flow rates will be in error by the difference between the actual pipe cross sectional
area and the area calculated using the incorrect pipe OD or pipe wall thickness values .
Pipe Wall Thickness Gauge Automatic Use
OTEE:
N
There are two different “reference” measurement methods required depending on the type of pipe being used . With
Tubing
the reference is checked with the transducer
ON
pipe, for all other pipe types the reference is set with the
transducer
OFF
the pipe .
OTEE:
N
Pipe thickness transducer must be applied perpendicular to the long axis of the pipe/tube (See
Figure 64
) .
1 . Make sure
Setup > ANSI Pipe > ANSI Schedule
is set to “Use Manual Entry” as in
