* This error is pulse output results calibrated under standard operating conditions at Toshiba’s
flow calibration facility.
* Individual meter’s measurement error mayvary up to ± 0.8 % of Rate at 3.28 ft/s (1.0 m/s) or
more and ± 0.4% of Rate ±0.157 inch/s (4mm/s) at 3.28 ft/s or less.
* Refer to individual calibration data for each meter’s measurement error.
•
For partially filled pipes detectors (Combined detector is LF502)
± 2 % FS
Note: Accuracy is measured when detector and converter are newly combined under the basic
operating conditions in the Toshiba calibration facility.
