    PART 2 - TRANSDUCER INSTALLATION General The transducers that are utilized by the Series TFXL contain piezoelectric crystals for transmitting and receiving ultrasound signals through walls of liquid piping systems. DTTN and DTTH transducers are relatively simple and straight-forward to install, but spacing and alignment of the transducers is critical to the system's accuracy and performance.

  • Page 22: Transducer Installation

    PART 2 - TRANSDUCER INSTALLATION 1. Mounting Location The first step in the installation process is the selection of an optimum location for the flow measurement to be made. For this to be done effectively, a basic knowledge of the piping system and its plumbing is required.
