o.f.s. = of full scale value
When there is a difference between the temperature at zero point adjustment and the
process temperature, the typical measured error of the sensor is
DN 25 (1"): ±0.0001 % o.f.s./°C (±0.00005 % o.f.s./°F)
DN 50, 80, 100 (2", 3", 4"): ±0.00015 % o.f.s./°C (±0.000075 % o.f.s./°F)
Density
When there is a difference between the density calibration temperature and the process
temperature, the typical measured error of the sensor is
±0.015 kg/m 3 /°C (±0.0075 kg/m 3 /°F)
