- DDA-FC and DDA-FCM feature the FlowControl system, which detects overpressure, line bursts and air bubbles in the dosing head and suction-side cavitation.
- With the built-in dosing timer, you can set up batch dosing either as a simple repeating cycle or for up to 16 procedures over the course of a week.
- The automatic deaeration function stops air bubbles from building in the dosing head so your dosing process does not stop due to air-locking.
- DDA-FCM features FLOWADAPT, which ensures that your dosing accuracy is maintained even when system pressure fluctuates.
