We recommend Reflect mount whenever possible. This is the simplest way to mount the transducers. Also, Reflect mount resists abnormal flow profile conditions such as
Direct mount provides a shorter sonic beam path. This can improve performance with sonically attenu- ative liquids or pipe materials. We recommend using Direct mount for plastic pipes. Compared to Direct mounting, Reflect mount requires almost double the amount of a mounting length. Therefore, Direct mount may be the only option if the availability of mounting space is limited.

3.1.4 PREPARING THE PIPE
1.Pick a mounting location with the longest straight run. You must have easy access to at least one side of your pipe. The mounting location must remain full, even at zero flow.
2.Decide on your mounting mode (Direct or Reflect). Always use Reflect Mode whenever possible. You may only need to use Direct Mode if your pipe is plastic.
3.After receiving the spacing dimensions from the Installation Menu, prepare the pipe surface. De- grease the surface, if necessary, and remove any grit, corrosion, rust, loose paint, etc. Use abra- sive material provided to provide a clean contact surface for the transducers.
4.Refer to the next sections for illustrated instructions on how to locate each area to be cleaned and how to use each mounting option.
Please note that the instructions show vertical mounting for clarity purposes only. Do not install transducers on the top of a pipe.
