The Smith Meter Model H8 is an 8-inch, steel, double-case, straight-through rotary vane positive displacement (PD) meter used for custody transfer, batching, blending, dispensing and inventory control of petroleum products, oils, solvents, chemicals and similar liquids. Smith's offset inlet and outlet nozzles keep pressure drop across the measuring chamber low, which minimizes slippage and preserves accuracy, and a high-torque calibrator adjusts registration in 0.05% steps.
Key specifications

How to specify / order
The H8 bulletin gives a model designation and ordering checklist rather than a position-by-position catalog code. Provide the following with your RFQ:
Model designation: H8-S#, where S# is the pressure rating: H8-S1 = Class 150, 150 psi; H8-S3 = Class 150, 285 psi; H8-S5 = Class 300, 300 psi; H8-S6 = Class 300, 740 psi; H8-S7 = Class 600, 1,480 psi; H8-S8 = Class 900, 2,220 psi
Application: Batching, loading, blending, inventory, custody transfer, process control
Operating conditions: Liquid name and gravity; minimum/normal/maximum flow, temperature and viscosity; maximum working pressure
Seals: Buna-N (standard), FKM/Viton or PTFE
Units of registration: Gallons, barrels, liters, dekaliters, cubic meters, pounds, kilograms
Direction of flow: Left-to-right standard; specify right-to-left if required
Options / accessories: Trim, clearances, counters, pulse transmitters, ATC/ATG, strainer, air eliminator, valves
