§2.6 Steps to Configure the Parameters
The following parameters need to be configured for a proper measurement:
(1) Pipe outer diameter
(2) Pipe wall thickness
(3) Pipe materials (for non-standard pipe materials*, the sound speed for the material must be
configured too)
*Standard pipe materials and standard liquids refer to those with the sound parameters that have
already been programmed into software of the flow meter, therefore there is no need to configure
them
(4) Liner material and its sound speed and thickness, if there is any liner.
(5) Liquid type (for non-standard liquids, the sound speed of the liquid is also needed)

transducers will be the selected option.
