Using the above scheme, the vortex-shedding meter of the utility model can easy disassembly eddy generator, it is convenient for safeguarding more
It changes；Shock absorption strip is set inside eddy generator hollow simultaneously, medium impact vibration caused by eddy generator can be weakened,
And then improve the detection precision of flow sensor.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the vortex-shedding meter that the utility model has detachable eddy generator.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Referring to Fig. 1, the utility model provides a kind of vortex-shedding meter with detachable eddy generator, comprising: even
It connects in the two housings 1 on pipeline, the attachment base 2, removably that is connected between two housings 1 and by two shells 1
Connecting tube 3 on the attachment base 2, the elastomeric pad 10 between the attachment base 2 and connecting tube 3, be set to it is described
The Flow Measurement Display Meter 4 of 3 top of connecting tube.It is provided with flow sensor 5 in the connecting tube 3, specifically, the flow sensor
5 can be realized flow sensing and transmitting signal, being connected and fixed in the connecting tube 3 using existing flow sensor
Mode also uses the prior art can be realized and fixes the flow sensor 5 and do not shake.The flow sensing
Device 5 is electrically connected with the Flow Measurement Display Meter 4 by connecting line 6, and the flow sensor 5 is provided through the attachment base 2 and prolongs
