your application. We will make a recom-
mendation about the best place for
installation, determine your adjustment
factor, and tell you what degree of preci-
sion you can expect—all free of charge!
For a small fee to cover costs, your local
sales representative can take the perti-
nent measurements on-site if you prefer.
The data provided by ImproveIT can even
be transferred to dynamic pressure
probes made by other manufacturers
with a slight increase in the error factor. Deviation Deltaflow installation 2 D after a pipe elbow.There are significant deviations without ImproveIT;
all values are better than 1% with ImproveIT This is the information we need in order to determine your
ImproveIT adjustment: • Dimensioned conduit isometry, including inlet and outlet flow disturbances• Conduit interior diameter and wall thickness measurements
• Planned and/or current installation site for the dynamic pressure probe
• For previously existing metering equipment: probe type and probe specification sheet
• Medium, pressure, temperature, and flow ranges An example of a double pipeelbow on multiple levels:
Most flow meters require an
inlet path of 20 to 40 D . The
deltaflow can be installed
after only 1 D with a very
small degree of error. After
only 7 D, the error factor of
the deltaflow enhanced with
the ImproveIT database is
less than 1%. 9
