§4.6.7 inserting the transducers
screw the screw mut to a position under the bottom of the transducer and screw the transducer
through the ball valve to ball valve spool. Open the ball valve and continue to screw the transducer
until the head of transducer passes the inner wall of the pipe. Before the wires
are connected, the angle of the transducer should be adjusted to make sure that the head of two
transducers can be in face to face position so as to send and receive the signals properly(the hole
for line of two transducers should be upward or downward at same time).and then fix the screw
mut,connect the wires,use silicon rubber to seal the connection place.
§4.6.8 Length calculation of the part of transducer into the pipe inner wall:
Insertion style transducer is made of stainless steel by casting. As the transducer's length A and
the pipe wall's thickness B are known, and the length part of transducer left
outside the pipe can be measured, the length of the inner part of the transducer can be
calculated through the formula: L=A-B, C=0
Note: the length A of different types of transducers are: Standard insertion type B: A=170mm;
Standard insertion type C: A=220mm, and Cement insertion type B: A=310mm.
§4.6.9 wiring
After wires being connected, screw the mut on the hole for wires (do not lose packing seal),at
last,screw seal cover tightly to prevent water leakage.
