Preliminary installation procedures
Introduction
To install the sensors these basic steps must be followed:
1. Program parameters into transmitter
2. Mount the sensors on pipe using parameters from transmitter
3. Connect sensor cables from sensor to transmitter
Clamp-on sensor mounting modes
All though the transmitter recommends a mounting mode after analyzing your pipe and liquid
data entries you can still install clamp-on sensors in the way that best suits your application
and the sensor type you have purchased.

Reflect mount is recommended whenever possible. This is the simplest way to mount the
sensors. Also, Reflect mount resists abnormal flow profile conditions such as cross-flow
within the flow stream. In addition, Reflect mount may be the only possibility if conditions do
not allow access to the opposite side of the pipe.
Direct mount provides a shorter sonic beam path. This usually improves performance with
sonically attenuative liquids or pipe materials. Direct mount is recommended for plastic
pipes. Compared to Direct mounting, Reflect mount requires almost double the amount of
mounting length. Therefore, Direct mount may be the only option if the availability of
mounting space is limited.
