2. Measurement accuracy: (Accuracy when combined with detector)
• Combined detector: LF470 (Meter size 1/10” to 1/4” (2.5 to 6mm))
Range
Flow rate to the range (%)
1.0-3.3ft/s
(0.3-1.0m/s )
3.3-32.8ft/s
(1.0-10m/s )
0 to 50 % ± 0.8 % FS ± 0.4 % FS
50 to 100 % ± 0.8 % FS ± 0.8 % of rate
• Combined detector: LF150 (Meter size 20” to 120” (500 to 3000mm))
±0.5 % of Rate
*
* 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.
