Linearity Model 3415 4-path chordal design combined with a single-
path bounce design
• 4-path chordal design
- Flow calibrated accuracy is ± 0.1% of reading over
the entire flow calibration range
- Without flow calibration, accuracy is typically ± 1%
of actual volume flow
1
(10" and smaller line sizes)
and ± 0.7% (for 12" and larger line sizes)
• Integrated check meter
- Flow calibrated accuracy is ± 0.2% of reading entire
flow calibration range
- Without flow calibration, accuracy is typically ±1.5%
of actual volume flow

tire flow calibration range
- Without flow calibration, accuracy is typically ± 1%
of actual volume flow
