General specification:
DSP measurement technique – The PF220 uses ‘transit time’ measurement with a sampling resolution of 50 pico-
second, with a continuous signal level indication to the display
Flow velocity range (bi-directional) – • Minimum velocity 0.1m/s
• Max velocity 20m/s
Flow measurement accuracy – • ±0.5% to ±2% of flow reading for flow rate >0.2m/s and Pipe ID >75mm
• ±3% of flow reading for flow rate >0.2m/s and Pipe ID in range 13mm - 75mm
• ±6% of flow reading for flow rate < 0.2m/s
•
Flow velocity corrected for Reynolds number over entire velocity range
Repeatability – • ±0.5% of measured value or ±0.02m/s whichever is the greater
Response time – • < 500ms depending on pipe diameter
Selectable flow units – • VELOCITY: m/sec, ft/sec
• VOLUME: l/s, l/min, l/h, gal/min, gal/h, USgals/min, USgals/h, Barrel/h,
Barrel/day, m³/s, m³/min, m³/h
Selectable volume units – • l, gal, USgals, Barrel, m³
Total volume – • 12 Digits - forward and reverse
Display languages – The following operator languages can be selected from the PF220 set-up menu
• English
• French
• German • Italian
