Description
The Smith Meter Model E3 is a 3", double-case, straight-through (S3 through S8), rotary vane type positive displacement meter.
Applications for the E3 include blending, batching, dispensing, inventory control, and custody transfer of oils, solvents, chemicals, paints, fats and fertilizers.
Features- Superior accuracy―Smith Meter's rotary-vane meter principle, combined with the meter’s uniquely designed (offset) inlet and outlet nozzles, maximizes accuracy by minimizing pressure drop across the measuring chamber reducing slippage (flow through meter clearances)
- Low pressure drop―Streamlined flow path provides low pressure drop
- Positive and accurate registration―High-torque drive calibrator with adjustment in 0.05 percent (%) increments ensures accurate registration
- Long service life―Low-friction ball bearings, fixed cam-type timing, and rugged construction provide sustained accuracy and long service life
- Options:
- High-viscosity meter clearances extend operation at maximum flow rate from 400 to 2,000 millipascal-second (mPa•s)
- High-temperature clearances extend operating temperatures from 150 to 200 degrees Fahrenheit (°F) (65 to 93 degrees Celsius (°C))
- All iron trim option for operating temperatures above 200°F (93°C)
- Liquefied petroleum gas (LPG) trim option for low-lubricity liquids, such as LPG
- Compliant with NACE standard MR0175
- ASME Section VIII vessel construction is available for model E3-S3

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)
Repeatability
- ± 0.02 %
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
