The Smith Meter Model T-40 is a 4-inch, single-case, angle-type rotary vane positive displacement meter used for blending, batching, dispensing, inventory control and custody transfer of oils, solvents, chemicals, paints, fats and fertilizers. The rotary vane principle keeps pressure drop across the measuring chamber low to limit slippage, the calibrator adjusts in 0.05% steps, and ball bearings with fixed cam timing give long service life. Cast iron is standard, with an aluminum housing option for low temperatures.

How to specify / order
The bulletin gives an ordering checklist rather than a position-by-position model code. Provide the following with your RFQ:
Application: Batching, loading, blending, inventory, process control
Operating conditions: Liquid name and gravity; minimum/normal/maximum flow, temperature and viscosity; maximum working pressure
Seals: Buna-N (standard), Viton or PTFE
Units of registration: Gallons, liters, pounds, kilograms
Inlet/outlet position: 1-A standard; specify another position (e.g. 2-C) if needed
Options / accessories: Housing material, high-viscosity or high-temperature clearances, counters, pulse transmitter, ATC/ATG
Pricing and lead time are quoted per configuration. Send the model code (or your application details), product, flow range, and pressure/temperature to Flow Measurement Services for a quote.
