Maximum Flow Rate
- Continuous Rating with Standard Trim: 420 USGPM (1600 L/min)
- Intermittent Rating with Standard Trim: 500 USGPM (1900 L/min)
- Continuous/Intermittent Rating with all Iron or LPG Trim: 315 USGPM (1200 L/min)
Viscosity
- Standard: 400 mPa.s (2,000 Seconds Saybolt Universal (SSU)) maximum
- Optional: 2 pascal seconds (Pa.s) (10,000 SSU) maximum and specify “High Viscosity Meter Clearances”
- Over 2 Pa.s: Specify ”High Viscosity Meter Clearances” and derate maximum flow rate in direct proportion to viscosity over 2 Pa.s. For example, at 4 Pa.s, derate maximum flow rate to 50 % of normal continuous rating 210 USGPM
