Overview of comparison
 Transfer
 Test
flowrates: (5 to 30) L/s, 11 flow points
 Original
 New
standard: 4" PD meter (Kral)
Cardinal point: Re= 76 150
comparison point: Re= 120 000
 Comparison
parameter: Strouhal No.
Strouhal = K × D3

Summary of the Comparison
• CMS tested the TS with solvent oil @ 20 ℃ and
35 ℃ (Comparison point @ 34.9 ℃)
• VMI tested the TS with kerosene @ 29.0 ℃ to
36.4 ℃ (Comparison point @ 29.3 ℃)
• NMIJ was invited to perform tests with kerosene
and light oil @ 20 ℃ and 35 ℃
• Comparison was made without viscosity correction
• The En value of VMI at Re=120000 is 0.28
• Operation condition of CMS is quite different from
that in CCM-WGFF key comparison. No linkage to
KCRV was provided.
