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 µA
Pulse/frequency output
Accuracy Max. ±50 ppm o.r.

Influence of medium
temperature
Mass flow and volume flow
When there is a difference between the temperature for zero point adjustment and the process
temperature, the typical measured error of the sensor is ±0.0002 % of the full scale value/°C
(±0.0001 % of the full scale value/°F).
Density
When there is a difference between the density calibration temperature and the process
temperature, the typical measured error of the sensor is ±0.0001 g/cm
