Performance
SB25X Linearity Standard Rotors
+/- 0.15% Over Standard Flow Range
+/- 0.25% Over Extended Flow Range
Repeatability: +/- 0.02%

Operating Temperatures Limits:
Dependant on pick off type and O-Ring
seals used, see Table 1.
To convert pressure drop value to the actual
process fl uid, use the following equation:
ΔPA = (cPA)
0.25
*(SGA)
0.75
* ΔPm
ΔPA = Pressure Drop on Actual Fluid in PSI
cPA = Viscosity of Actual Fluid in cP
SGA = Density of Actual Fluid in SG
ΔPm = Pressure Drop on Mineral Spirits (See Figure
3 on Page 6 for Reference.)
