1.8 Mounting the Clamp-on Fixture and Transducer System
The AT600 transducer system includes one or two clamp-on fixtures, two transducers and one transducer
cable. One clamp-on fixture is shipped with both transducers installed and the transducer cable connected
to the transducers. This fixture is the default setup for most applications. If a second fixture has been
ordered, it is shipped empty.
Transducers available for use with the AT600 flow meter are listed in Table 1 below.
The AT600 clamp-on fixture and AT6 transducer system can be installed on pipe sizes 2 in. (50 mm). For
optimum performance in any specific application, either a two-traverse or one-traverse installation can be
chosen. Because the maximum pipe size for a single clamp-on fixture is 250 mm for 2 MHz transducers or
320 mm for 1 MHz and 0.5 MHz transducers, the detailed installation requirements differ based on the
calculated transducer spacing and the chosen number of traverses. Refer to Table 2 below to find the
parameters for your specific configuration.
IMPORTANT: See “Sensor Setup” on page 66 to calculate the required transducer spacing. A two traverse
installation is recommended for most applications.
IMPORTANT: If there is any type of coating or protective layer on the outer pipe surface, it must be removed at
the locations where the transducers and couplant contact the pipe surface.
