 III

5511-229 GB/98.06/Rev. B1

14

If the difference in length (

D

l) between the two sensors is greater,

a correspondingly bigger cable cross sectional area (Q) should be
used, as indicated in the following diagram:

Provided the difference in length between the flow and return
sensor cables - as shown in the diagram  are strictly observed, the
error increment on the differential temperature will be less than
0.02 K.

4.3.1 Average Measurement

If the pipe dimensions are larger than DN100, stratified water
temperatures may occur. If this should happen, average measure-
ments should be ascertained by inserting 4 or 5 sensors in each
pipe.
