Dual Path Energy
Dual Path Energy uses two measurement channels to achieve a single output via a “virtual” third channel.
The resultant data is the average of the two channels. Only clamp-on or in-line transit-time operation is
allowed. Benefits include highest available precision and enhanced immunity to distorted flow profile
conditions.
Channel 1+2 Energy
Channel 1+2 produces a data output via a virtual Channel 3, proportional to the sum of the liquid and
energy flow of two independent pipes. This requires setting the two channels to operate independently.
Only clamp-on or in-line transit-time operation is supported.

Dual Channel Energy
Dual Channel Energy provides two independent measurement channels that operate simultaneously.
Depending on the specific model, Dual Channel Energy supports: Clamp-on Transit-time, In-line transit-
time and Reflexor.
NOTE: A Reflexor-enabled channel does not provide energy data.
