1. Stated reference accuracy equations include terminal based linearity, hysteresis, and repeatability, but does not include analog only reference accuracy of ±0.005% of
span.
2. RDG refers to transmitter DP reading.
3. Ultra for Flow is only available for Rosemount
™
3051SMV DP Ranges 2–3. For calibrated spans from 1:1 to 2:1 of URL, add ±0.005% of span analog output error.
4. Specifications for process temperature are for the transmitter portion only. The transmitter is compatible with any Pt 100 (100 ohm platinum) RTD. Examples of
compatible RTDs include Rosemount Series 68 and 78 RTD Temperature Sensors.

1. Total performance is based on combined errors of reference accuracy, ambient temperature effect, and line pressure effect. Specifications apply only to differential
pressure measurement.
2. Ultra for Flow is only available for Rosemount 3051SMV DP Ranges 2–3.

1. Applies to the 3051SMV_M Multivariable
™
type only. 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.
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.
