3.
Twist off the locknut and loose the lock ring, pull the transducer into the joint nut, and then screw up the
joint nut on the ball valve.
4.
Open the ball valve and insert the transducer, measure the dimension from the outer surface of the pipe to the
front end surface of handspike position to meet the following formula:
H = 175 - d
In this formula:
H is Mounting height (mm);
175 is Transducer length (mm);
d is Pipe wall thickness (mm).
5.
Tighten the nut slightly, make the locking ring press the transducer, rotate the connector, make the
installation direction of the connector consistent with the pipe axis and outward, and finally tighten the nut.
6.
Connect the transducer cables to the corresponding upstream / downstream ( upstream = red, downstream =
blue ) terminal ends.
7.
Please refer to the following installation diagram(vertical view):
Important
The direction of the connector shall be consistent with the center line of the pipeline under test
and outward, otherwise the sensor will not receive the signal.
On the horizontal measuring pipeline, the sensor must be installed in the positive side position
(i.e. 3 o'clock, 9 o'clock position), because there are often bubbles or air pockets in the upper
part of the pipeline, and sediment at the bottom, which causes signal attenuation.
