Table of inlet and outlet sections

7
The following table shows the necessary equalizing sections in relation to existing obstructions. The table
gives the respective minimum values which are required. If it's not possible to observe the indicated
equalizing sections considerable deviations in measuring results must be expected.
Flow obstruction
in front of the measuring section
Slight curve (bend < 90°)
Reduction
(pipe narrows towards the meas. section)
Expansion
(pipe expands towards the meas. section)
90° bend or T piece
2 bends @ 90° on one level
2 bends @ 90°
3-dimensional change of direction

The sensor head has to be mounted in the center of the pipe. For this
purpose the probe shaft has a scale. In order to find out the right position
please determine the insertion depth by means of the drawing at the left
hand side.
Insertion depth = x +y
x = dA/2
Scaling on the shaft
Reference level for reading the insertion depth at the scale
dA = Outer diameter of the pipe
