Flow Controlled Micropump mp6
The flow control in micropump mp6 can be realized by two different approaches:
The mp6 micropump with the double actuator provides an intrinsic sensor function. The reversible piezo effect can be used for actuation (pumping) and sensing mode. By continuous operation between pumping and feedback mode, no significant drop of pump performance is observed. Lower accuracy, in the order of 10%, can be achieved based on the intrinsic sensor function for the feedback signal. Especially at higher flow ranges under varying system conditions (e.g. pressure conditions at the in- and outlet) the piezo sensor principle provides constant performance.
For applications in the lower flow range with higher accuracy demands the closed-loop can be achieved by micropumps equipped with thermal flow sensors as sensing element. Accuracies in the range of 2-5% can be achieved by such hybrid systems.
In both cases smart system electronics will give the user access to the system status and also allowing the manual administration of additional bolus rates. Both approaches offer interesting new potential for various applications, especially where small, portable and battery powered systems are required. Depending on the detailed requirements a custom fit system can be evaluated and realized.
