In summary, the present invention can monitor liquid in real time by integrated pressure detection means and flow detector on pump
The pressure and flow of body, and without extraly increasing pressure gauge and the single two sets of measuring systems of flowmeter again, reduce body
Product and weight, while reduce when additionally increasing pressure-detecting device and flow detector caused by the required joint used
Caused bubble in crushing and fluid, can quickly stop-spraying in the system set up jointly with shower nozzle.Also, pressure detecting fills
Put and be integrated in flow detector on pump so that the maintenance and replacing in later stage are more convenient.Said pump is applied to removable
On platform or aircraft, the load of moveable platform or aircraft can be saved, and can monitor in real time liquid pressure and
The change of flow.
Embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this
The equivalent structure or equivalent flow conversion that description of the invention and accompanying drawing content are made, or directly or indirectly it is used in other correlations
Technical field, it is included within the scope of the present invention.
