2.5 STEPS TO CONFIGURE THE PARAMETERS
The following parameters need to be configured for a proper measurement:
(1)
Pipe outer diameter (O.D.)
(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)
(6)
Transducer type adapted to the flow meter. Generally the Standard M1 or the Frame
M-sized transducers will be the selected option.
(7)
Transducer mounting methods (the V-method or Z-method is the common option)
(8)
Check up the Space displayed on M25 and install the transducers accordingly.
For standard pipe materials and standard liquids, the following detailed step-by-step setup is
recommended.
