Standard or Normal Volumetric Capability
Standard and normal volumes are “quasi mass” flow units for any fixed composition fluid. Standard and normal volumes do not
vary with operating pressure, temperature, or density. With knowledge of density at standard or normal conditions (available from
reference sources), a Micro Motion meter can be configured to output in standard or normal volume units without the need for
pressure, temperature, or density compensation. Contact your local sales representative for more information.
