Troubleshooting
1 A. Are you absolutely certain that the piping is completely filled?
□
2 A. Can you exclude gas load on the medium? Is a pump close
by?
If there is gas load:
•
Are the transducers installed at the 10 AM or 2 PM
position on the horizontal pipe?
•
If there is gas load on the medium, is there an option of
mounting the transducers to a vertical pipe? If yes, mount the
transducers to a vertical pipe.
□
3 A. What is the solid particle content of the medium?
□
4 A. Are you absolutely certain of the wall thickness? Check the
piping for the presence of engraved information that may be of
relevance. Hot water piping is subject to the formation of lime
deposits that may propagate the deposit of solid particles of media
with high content thereof. Use a wall thickness meter. You can
lease or purchase a wall thickness meter from systec Controls.
check the wall thickness entry on the device.
□
5 A. Did you enter the
outer diameter
of the pipe, or its
circumference
? Check the corresponding values once again.
Please make sure that you did not mix it up.
□
6 A. Have you selected the correct piping material? You are certain
that the
piping is not lined
? When taking measurements on a pipe
made of concrete you must presume that this piping does not have
sound conducting properties. Check the parameterized values
once again.
□
7 A. Does the ultrasonic transducer match the application
with regard to pipe dimensions and medium temperature?
Is the
□
A. No measurement at all
