Step4. Open the ball vale and insert the transducer into the pipe, and measure the length
between the outer side and the handle mark (H), trying to make it conform to the following
formula:
H = 216 –d1-d2
In which:
d1-Pipe wall thickness (mm)
d2-Liner thickness (mm), if there is no liner, then d2=0.
H -Installation height (mm)= Length between the outer side and the handle mark (mm)
216-Fixed length of standard W1 type insert-in transducer (mm); In special cases, if you need to
lengthen the transducer, please contact the manufacturer.
Step5. Slightly tighten the nut to make the lock ring press on the probe, rotate the wrench to
make the orientation lever point at the center of two transducers. Please ensure the UP/ DOWN
arrows at the transducer marks are identical with the signal direction of the ultrasound
transducer, and finally tighten the nut.
Step6. Connect the transducer cables and ensure correct connections of the
upstream/downstream transducer.
Step7. Please refer to the schematic diagram for installation:
