SECTION 3.0 INSTALLATION
3.1 OVERVIEW
Each FP-4400 Portable Clamp-on Ultrasonic Flow Meter is provided with three different pairs of matched ultrasonic
transducers. 10 Series transducers are optimized for small pipes, 20 Series transducers are optimized for mid-range pipe
sizes and 30 Series transducers work best on larger pipes. The transducers are mounted (clamped) on to the outside wall
of the pipe with the included mounting hardware. 12 ft triaxial cables convey the transducer signals to the meter enclosure
that provides power, signal processing and a user interface display.

Ultrasonic transducers may be configured to operate in either 1 (Direct), 2 (Reflect) or 4 (Double Reflect) cross operating
modes. In double reflect mode the signal reflects off the pipe wall twice. The meter will recommend the operating mode
once you select the transducer type and enter the pipe data (Pipe material, size, etc.). In most cases, the meter will select
In most cases, the meter will select 2 cross (Reflect). Reflect mode is the simplest mounting configuration. Direct mode
is normally only used to optimize signal strength and double reflect mode is only used on very small pipes. For each
installation, the meter will provide the proper transducer spacing distance based on the pipe data you program into the
meter.
