Below a dosing flow of 10 % no precise
measurement is possible. The current
signal 4 mA may probably not be
reached at a dosing flow of 0 %.
Deviation of linearity
< ± 4 % from upper limit of the measuring
range
Current output
4-20 mA
4 mA equals to 0 % dosing flow
20 mA equals to 100 % dosing flow
Power supply
