A kind of improve the effect of vortex street flowmeter using vortex occurred

Technical background of vortex flowmeter is mainly used for industrial piping medium fluid flow measurement, such as a variety of media such as gas, liquid and vapor, the principle of vortex generator is generated by the vortex occurred body spiral thirsty, by detecting the frequency of vortex separation fluid velocity or flow rate, to calculate the pipe flowmeter test probe under the impact of the medium to long term damage easily, and ordinary produce spiral vortex happens when reach the measuring probe are faint due to inaccurate measurement. The utility model provides a utility model content to improve the effect of vortex street flowmeter using spiral body thirst, purpose is to solve the above situation, improving the measuring accuracy of vortex flowmeters, and improve the service life of the meter. Of the technical scheme of the utility model, a kind of improve the effect of vortex street flowmeter using spiral body, consists of ontology, limit groove, described in the ontology for vertical suspended section into isosceles trapezoid strip body, two sides symmetry waist level of ontology inward concave arc surface, top edge of trapezoidal cross-section of ontology in face limited a trough, described limit slot for top-down semicircular canals along the surface of the vertical Central Line. The advantages of the utility model, the utility model has simple structure, low cost, easy to use, improving the measuring accuracy of vortex flowmeters, improve the service life of the meter. Figure 1 illustrated instructions for the utility model structure diagram. Concrete implementation way of a kind of improve the effect of vortex street flowmeter using vortex occurred, including ontology 2, limit slot 3, 2 of ontology for the vertical suspended section into isosceles trapezoid strip body, body two side waist level of symmetrical inward concave arc surface, ontology trapezoidal section 2 top edge is in open, limited a slot 3 limit slot 3 for along the surface of the vertical line from top to bottom of semicircular canals, the spiral body limit of bad 3 play round measuring probe can be fixed and arc side 1 to generate offset the effect of the vortices, limit slot 3 to a certain extent, to protect the measuring probe.
Nowadays, it is very common for us to utilise in vortex flow meter manufacturer. And the quality of is decisive to production efficiency.
