Accuracy of outputs
o.r. = of reading; o.f.s. = of full scale value
The output accuracy must be factored into the measured error if analog outputs are used, but can be
ignored for fieldbus outputs (e.g. Modbus RS485, EtherNet/IP).
Current output
Accuracy: Max. ±0.05 % o.f.s. or ±5 μ A
Pulse/frequency output
Accuracy: Max. ±50 % ppm o.r.

Mass flow and volume flow (liquids)

Temperature
±0.25 °C ± 0.0025 · T °C (±0.45 °F ± 0.0015 · (T–32) °F)
Response time • The response time depends on the configuration (damping).
• Response time in the event of erratic changes in the measured variable (only mass flow): after
100 ms 95 % of the full scale value.
Influence of fluid
temperature
When there is a difference between the temperature for zero point adjustment and the process
temperature, the typical measured error of the Promass sensor is ±0.0003% of the full scale value / °C
(±0.0001% of the full scale value / °F).
