Note
When installing sensors, do not key in the V/M (Version/Modification) label number as the
Sensor Size.
Clamp-on Sensor Mounting Modes
The transmitter recommends a mounting mode after analyzing your pipe and liquid data
entries. However, you can 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. Reflect mount supports the AutoZero function, which zeroes the flowmeter
automatically without user-participation. 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. We recommend using Direct mount 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.
