Mounting Clamp-On Fixture Onto Pipe (At6 Transducers); Dual Traverse Installation At Transducer Spacing Range 0 To 250Mm - GE AT600 User Manual

Chapter 2. Installation

2.4.2 Mounting Clamp-on Fixture Onto Pipe (AT6 Transducers)

The AT600 transducer system contains one clamp-on fixture, two transducers embedded inside the fixture and one
transducer cable. The transducer cable is already connected with the transducers and assembled with the fixture before
shipment as a default setup for easy customer installation.
The AT600 clamp-on fixture and transducer system can support pipe size ranges from 2 inch to 24 inch.The customer
can choose either dual traverse installation or single traverse installation for transducer mounting on the pipe.
As the maximum measurement range of one clamp-on fixture is 250mm, there are different kinds of installation
configurations based on the transducer spacing range and dual or single installation method. See Table 1 below for
rough estimates.

250-750
250-750
Please see section 3.7 (Sensor Setup) for determining transducer spacing. A two traverse installation is recommended
for most applications.
2.4.2a

Dual Traverse Installation at Transducer Spacing Range 0 to 250mm

When the transducer spacing range is from 0 to 250mm, only one clamp-on fixture is needed for dual traverse
installation. See Figure 11 below for the dual traverse installation guide at transducer spacing range 0 to 250mm.
1. Install AT600 clamping fixture with transducers onto the pipe using the two mounting straps.
a. Choose location with enough straight run; refer to Figure 7 on page 7.
b. Install two straps onto the pipe with about 30 cm/1 ft apart.
