Monitoring unit for micro pump, has fluid reservoir arranged between inlet valve and outlet valve, and including flexible reservoir diaphragm area, and strain measuring strip detecting volume and/or pressure in reservoir
Monitoring unit for micro pump, has fluid reservoir arranged between inlet valve and outlet valve, and including flexible reservoir diaphragm area, and strain measuring strip detecting volume and/or pressure in reservoir
The unit (100) has an inlet valve (102), which is connectable with a micro pump or a pressure loaded supply reservoir. An outlet valve (104) outputs a monitored fluid flow (116). A fluid reservoir (110) is arranged between the inlet valve and the outlet valve, and has at least a flexible reservoir diaphragm area, which is formed by a sensor membrane area. A strain measuring strip is provided for detecting the volume and/or the pressure in the fluid reservoir. Independent claims are also included for the following: (1) a micro dosing arrangement with a micro pump and a monitoring unit (2) a method for monitoring a fluid flow by using a monitoring unit.
