Abstract
The utility model relates to a vortex street flow sensor, wherein, a sensor body is a welded triangle column, and one angle of the triangle column is welded with a cuboid. The utility model has the advantages of simple structure and convenient manufacture, and can measure medium flow and temperature technical data for pipeline inner diameter up to Phi 25.
Description
(1) technical field
The utility model relates to a kind of vortex street sensor that is used for throughput of flowing medium in the measuring channel.
(2) background technology
At present, the patent No. (CN9920015642) capacitance probe vortex flow sensors open file is a triangle column type (trapezoidal column type) or a square column type that welding is fixing, or their combined type column type vortex generation bodies separately are fixing perpendicular to the welding of sensor shell body axis, separated by a distance behind vortex generation body, or in combined type column type vortex generation body, parallel symmetrical cantilevered is fixed a probe, two metal fixed electordes that install with electrode suppor are housed in probe bore, and form differential capacitor change detection mode between the probe tube, said structure has certain anti-seismic performance, has improved the temperature range of measured medium.But it is very little that said structure can not be accomplished, can only measuring channel internal diameter ￠ technical data such as rate-of flow more than 25 and temperature.
(3) summary of the invention
In order to overcome above-mentioned defective, but the utility model provides the rate-of flow of a kind of measuring channel internal diameter ￠ below 25 and the vortex flow sensors of technical data such as temperature.
Structure of the present utility model is such, and a kind of vortex flow sensors is a triangulo column that welding is fixing, connects a rectangular parallelepiped at one jiao.
But the beneficial effects of the utility model are rate-of flow and the technical data such as temperature of measuring channel internal diameter ￠ below 25, and are simple in structure, easily manufactured.
(4) description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Figure one is the utility model axis of no-feathering view.
Among the figure: 1. sensor body 2. rectangular parallelepipeds 3. flow signal converters
(5) embodiment
Embodiment:
In Fig. 1, the inner chamber of sensor body (1) is equipped with flow signal converter (2), is welded with a rectangular parallelepiped on one jiao in the triangle of triangulo column (1).
Claims (1)
1, a kind of vortex flow sensors is made up of sensor body, flow signal converter, it is characterized in that described sensor body is a triangulo column that welding is fixing, at a welded corner joint one rectangular parallelepiped of described triangulo column.
