- Installation
1) Weld or fix the valve base on the pipe (2 in figure 27).
2) Screw the ball valve (3 in figure 27) and tighten to ensure the seal. The valve must be opened
3) Insert the drill bit in the ball valve and tighten the seal gland (6 in figure 28) on the male threads (4 in
figure 27),so that there is no leakage. Fasten the power drill to rod (7 in figure 28).
4) Turn on the drill and drill pipe
5) Unscrew the seal gland and slowly pull out the drill; as soon as possible, close the ball valve to avoid leakage.
6) Use a meter, or a caliper to measure the A dimension.
Slowly insert the transducer into the valve support and open the ball valve.
Measure the distance “L” between the outer surface of the pipe and the upper part of the head of the transducer.
L=A-pipe thickness
The transducer insertion will be installed properly when the C dimension (in figure 29) will be equal to 0 (zero),
ie when L=A-B
To check the transducers ultrasonic signal emitting orientation (1 in figure 27), check that: :
1) the outputs cables of both transducers are oriented orthogonally to the pipe axis
2) the outputs cable on the transducers have the same direction
