Features and benefits
- The FlowControl system on the DDA prevents unwanted stoppages, even with variable process parameters such as fluctuations in system pressure.
The DDA provides an accurate diagnosis of the most common causes of faults that occur during dosing with diaphragm pumps. These faults are displayed in plain text in the alarm menu.
- The AutoFlowAdapt feature ensures that the dosing process continues with the required flow, even when subject to external influences. When dosing degassing media, for example, motor control is automatically adjusted as soon as air bubbles are detected so that they can escape out of the dosing head. Fluctuating system backpressure no longer impacts the required flow, either – the stepper motor’s speed regulation mechanism automatically compensates for deviations.
- The integrated flow measurement feature of the DDA makes costly additional measuring equipment unnecessary. The currently measured flow is shown directly on the display and can be integrated in the control system via the analog output or bus protocol if necessary.
