2.3 Site considerations
Proper installation of the PanaFlow™ LC is important to
achieve optimum performance from the system. The
following installation recommendations provide general
guidelines of how this system should be installed. If the
following recommendations cannot be met, please consult
the factory for a more detailed review of the application to
see what performance may be achievable. Following these
recommendations may not be the solution for all, since
every installation is different.
2.4 Clamping fixtures and
Transducer installations
Installation of clamp-on transducers for transit-time
measurements consists of mounting the clamping fixture
to the pipe and then mounting the transducers into the
clamping fixture. When installing transducers in clamp-on
applications, you can use one of the following methods to
hold the transducer against the pipe wall:
• Strap Clamping Fixture (SCF)
• Universal Clamping Fixture (UCF)
• General Clamping Fixture (GCF, permanent installation)
• Magnetic Clamping Fixture (MCF)
• Small Clamping Fixtures - 6” (150 mm) or 12” (300 mm)
long, with Velcro straps (SPCF)
This manual covers the installation for the Strap Clamping
Fixture (SCF), while the other fixtures can be found in the
Appendix B. Before beginning the transducer installation,
you must determine the number of traverses for your
configuration.
Note:
The accuracy and performance of the flowmeter
depends on the location, spacing, and alignment of the
transducers. This manual provides general instructions for
locating and installing most transducer types. However,
the specific spacing of your transducers is unique to your
installation.
2.4.1 Strap clamping fixture
The Strap Clamping Fixture (SCF) (see Figure 5 below) acts
as a spacing device, a transducer holder, and a transducer
aligner. The SCF includes two U-shaped blocks connected
by a slotted bar and four hose straps.
The SCF is strapped around the pipe, and the blocks are
used to hold the transducers in position for accurate
measurements. The blocks must be positioned properly
using the spacing dimension calculated by the flowmeter.
Then, the transducers are mounted into the blocks.
