PARAMETER SETUP 

 
Every time the unit is installed on a pipeline this setup procedure should be followed. For the 

following example let’s assume we know the external diameter of the pipe is 24” so we should 

expect to see a detected diameter of around 61cm. 
 

1.

 

With  the  unit  mounted  on  the  pipeline  switch  to  SETUP 
MODE 1. We see the screen to the left. Notice the strong 
transmit pulse and a weak reflection at 60cm 

 we know 

we  are  working  on  a  60cm  diameter  pipe.  The  signal  is 
too weak as it does not cross the threshold level (middle, 
horizontal  line)  so  the  diameter  is  not  being  detected. 
We will increase gain until it is well over this level. 

 
2.

 

After increasing gain, notice that when the signal crosses 
the  threshold  level  (middle,  horizontal  line)  the  correct 
diameter  is  detected.  It  would  be  enough  to  leave  the 
unit as it is now however there are some spurious signals 
immediately  before  the  main  reflection  which  cross  the 
maximum  noise  level  (bottom  horizontal  line).  We  may 
be able to reduce these by varying the pulse width. 

 
3.

 

After varying the pulse width we have found the position 
at  which  the  reflected  signal  is  proportionally  largest 
compared to the spurious signals before it. However, the 
overall  signal  strength  has  reduced  to  below  the 
minimum signal level (top horizontal line) so we need to 
turn up gain again. 

 
4.

 

After  increasing  the  gain  notice  we  now  have  a  good 
strong  signal  well  above  the  threshold  level  (middle 
horizontal  line),  the  maximum  signal  level  is  above  the 
minimum  signal  level  and  the  spurious  signals  are  well 
below  the  maximum  noise  level.  Also  we  can  see  the 
detected  diameter  reflects  the  position  of  the  first 
reflection  along  the  ruler.  It  may  be  necessary  to 
readjust  gain  and  pulse  width  a  few  times  to  iteratively 
reach these optimum settings. 

 
5.

 

Once  the  optimum  settings  have  been  determined  select  SAVE  GAIN  AND  PW  from  the 
display menu to save the settings. If this step is omitted then the settings will be lost next 
time the mode is changed or the unit is switched off. 

 
6.

 

Set DETECT COUNT as per section 3.3.11 SET DETECT COUNT. 

 
7.

 

Set INDICATOR DELAY as per section 3.3.12 SET INDICATOR DELAY. 

 
8.

 

Set MINIMUM DIAMETER as per section 3.3.13 SET MINIMUM DIAMETER. 

 
9.

 

Return to DETECTION MODE 0 and ensure that after the DETECTING DIAMETE

R… message 

the correct pipe diameter is displayed and that the signal quality is over 95%. The unit will 
then start waiting for a pig passage. If this is not the case re-enter SET UP MODE 1 and 
adjust settings as necessary.
