Hit power effect and produce certain displacement amount, the flow velocity (impulse force) of this displacement and fluid passes through survey into strict functional relation
The flow velocity of fluid can be calculated by measuring this displacement (namely impulse force), further draw the flow of fluid.In order to ensure
The stress of target piece is equal to the impulse force of fluid, and the presence of any frictional force is not allow in its displacement, otherwise will bring mistake
Difference.
Problems be present in existing target type meter：
（1）Return spring coefficient is unstable, causes flow operation unstable；
（2）Bearing friction coefficient is big, and the life-span is low；
（3）Crushing is big, and air-flow has some setbacks；
（4）Electronic circuit and Sensor section are in fluid passage, therefore easily by fluid（Such as combustion gas）Corrosion, hold
It is easy to aging.

The interior measuring chamber being provided with fluid entering channel and flow pass, the measuring chamber are interior oblique provided with face fluid entering channel
Face target piece, the inclined-plane target piece are hinged on housing；The flowmeter also includes displacement measurement component, differential pressure pick-up and computing
Device, institute's displacement measurement component include displacement transducer, target bar and connector, and institute's displacement sensors are fixed on fixed seat
On, one end of the target bar is located in displacement transducer, and the other end of the target bar is flexibly connected with connector, the connector
The other end be flexibly connected with inclined-plane target piece, institute's displacement sensors, differential pressure pick-up electrically connect with arithmetic unit.
Preferably, institute's displacement sensors are inductive displacement transducer.
Preferably, institute's displacement sensors are electromagnetic type displacement transducer.
Preferably, the connector is Flexible Connector.
Preferably, the connector is spring steel wire.
Preferably, the inclined-plane target piece is fixed on housing by rotating shaft, and the target piece and the water of fluid direction of advance

（2）Crushing is small, is not easily blocked, and flow velocity is steady.
（3）In target piece rotation process, the gravity of same position is constant（Back-moving spring and external force shadow without other devices
Ring）, it is reproducible, therefore accurate measurement.
（4）Displacement transducer and circuit be not in fluid passage, and not fluid affected, component is non-aging, uses
Scope is wider.
