(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) 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.
(3) RDG refers to transmitter DP reading.
(4) Ultra for Flow is only available for 3051SMV DP Ranges 2-3. For calibrated spans from 1:1 to 2:1 of URL, add ±0.005% of span analog output error.
Models Ultra

(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.
