10.0 Installing the Transducers
To install the Transducers, complete the following steps:
1. Select a clamp-on fixture mounting location on the pipeline which meets
the following requirements:
• A straight pipe run of at least 10 nominal pipe diameters (with no
fittings or bends) before the upstream transducer
• A straight pipe run of at least 5 nominal pipe diameters (with no
fittings or bends) after the downstream transducer
• A clearance of at least 6” from the outer edge of each end piece to the
nearest joint, welding or flange in the pipeline
2. Mount the Clamp-On Fixture on the pipe (not provided) in the selected
location, and set the Transducer Spacing to the value calculated by the
APP (see Figure 20 on page 22).
3. Mount the transducers into the clamp-on fixture.
4. Connect the transducers to the transmitter with the cables provided.
For reference, a completed PT900 installation is shown in Figure 21 below.
