MultiVariable Flow Performance

(1)

(1) Flow performance specifications assume device is configured for full compensation of static pressure, process temperature, density, viscosity, gas

expansion, discharge coefficient, and thermal correction variances over a specified operating range.

Mass, Energy, Actual Volumetric, and Totalized Flow Reference Accuracy

Models Ultra for Flow Classic MV

(2)

(2) Uncalibrated differential producer (0.2 < beta < 0.6 Orifice) installed per ASME MFC 3M or ISO 5167-1. Uncertainties for discharge coefficient, producer

bore, tube diameter, and gas expansion factor as defined in ASME MFC 3M or ISO 5167-1. Reference accuracy does not include RTD sensor accuracy.
