Installation steps of the clamp-on transducer are shown below:
Step 1: Firstly, determine the installation site of the two transducers on the pipe and remove all
iron rust, paint stains and dirt.
Step 2: Apply enough couplant on the first half (signal generating position) of the transducers
and place it on the pipe, press the transducers against the pipe and ensure there are no voids.
Step3: Lock the steel band clamps and check the installation spacing between the two
transducers; slightly adjust the spacing L1 to the value provided in M14 menu of the converter;
slightly adjust the two transducers to one horizontal plane.
Step4: Check whether parameters in M04 menu are within normal scope or not.
If not, DO check the following:
*
Check whether related field parameters in the converter are input correctly or not (pipe
diameter, wall thickness, material, liner, medium, etc.);
*
Check whether the installation spacing L is identical with the value shown in M14 menu or
not;
*
Check whether the transducers are installed in the proper position or not, whether the pipe
sections have any scales, distortions or weld seams or not;
Note: The following shows the
