2-Channel
Dual Channel provides two independent measurement channels that operate
simultaneously. Depending on the specific model, Dual Channel supports: Clamp-on Transit-
time, In-line Transit-time and Reflexor.

2-Path
2-Path flow meters use 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.
