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.
① Upstream Sensors ⑤ Pipe B Output Flow
② Downstream Sensors ⑥ Channel 2 for Pipe B
③ Channel 1 for Pipe A ⑦ Pipe B
④ Pipe A Output Flow ⑧ Pipe A
2-Path
2-Path flowmeters 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.
① Sensor Path 1 ③ Average= (Path 1 + Path 2) / 2
② Sensor Path 2 ④ Pipe (front view)
