16-position ro-tary switch for set point adjust-ment
* The specified values refer to operation with water at 20°C. Monitoring of fluids with higher viscosities is possible with the effect of deviations from the mentioned values.
If you order at least 25 units, individual set point tables can be implemented.
Technical data
Set point range (with decreasing flow) / accuracy
DN 15 0.5 ... 29.5 l/min / ±0,2 l/min and ±2% of set point DN 25 3 ... 100 l/min / ±0,8 l/min and ±4% of set point DN 40 7 ... 275 l/min / ±2,0 l/min and ±6% of set point
Set point adjustment
16 different set points selectable by means of a 16-position rotary switch
