Smith Meter® PD Meters

The Smith Meter® Model SD-30-DI (Ductile Iron) and
SD3-S1 (Steel) Meters are 3", Class 150 ANSI, R.F.
Flange, single-case, rotary vane, positive displacement
meters. Applications include: blending, batching,
dispensing, inventory control, and custody transfer
of oils, solvents, chemicals, paints, fats, and fertilizers.

Features
• Superior Accuracy – The Smith Meter® Rotary
Vane Meter principle, combined with the meter’s
uniquely designed (offset) inlet and outlet nozzles,
minimizes pressure drop across the measuring
chamber, which reduces flow through meter
clearances to maximize accuracy.
• Low Pressure Drop – Streamlined flow path Operating Specifications
provides low pressure drop.
• Positive and Accurate Registration – High Maximum Flow Rate
torque drive calibrator with adjustment in 0.05% USGPM L/min
increments ensures accurate registration.
Continuous Rating – Standard Trim 320 1,200
• Long Service Life – Low friction ball bearings,
Intermittent Rating1 – Standard Trim 400 1,500
fixed cam-type timing, and rugged construction
give sustained accuracy and long service life. Continuous / Intermittent Rating – All Iron
