Description
Technical field
The present invention relates to flow rate and direction measuring device and method thereof that a kind of measurement flow rate simultaneously flows to.
Background technology
The sensor that existing measurement flow rate flows to mainly adopts acoustically, traditional mechanical formula and heat-sensitive type.Though acoustically is measured accurately, price is higher, and is difficult to accomplish microminiaturization.The traditional mechanical formula is adopted as impeller or three cup type measurement flow rate more, must adds to flow to the moving angular displacement sensor of marker tape and measure the flow direction.This traditional approach volume is big slightly, mechanical part is more.The heat-sensitive type purposes is narrow, is used for measuring channel wind speed etc. more, in addition environments for use such as humidity, dust is had relatively high expectations.
Summary of the invention
The purpose of this invention is to provide a kind of method and apparatus that resolves the flow direction by measurement flow rate---flow rate and direction measuring device and method thereof, to remedy the deficiencies in the prior art.
The present invention is on the basis of existing vane type flow measurement sensor, it is conceived substantially is to adopt two central shafts vertical mutually, and rigidly connected impeller flow measurement sensor is measured two mutually orthogonal velocity vectors in the flow field simultaneously, rely on existing data acquisition processing device again, again by existing software vector synthetic can obtain true flow velocity and relative current to.If again in conjunction with electronic compass, be not difficult to calculate the true flow direction.
So technical scheme of the present invention: it comprises an impeller flow measurement sensor, it is characterized in that it also comprises connected another impeller flow measurement sensor, and the central axis of these two impeller flow measurement sensors is mutually orthogonal all-in-one-pieces.
The radial dimension of two above-mentioned impeller flow measurement sensors is identical or different.
Measuring method of the present invention is: at first two these devices of the mutually orthogonal all-in-one-piece of impeller flow measurement sensor are put into the flow field, just can obtain two mutually orthogonal velocity vectors respectively, it is synthetic to rely on data acquisition processing device to carry out vector then, just can calculate or demonstrate true flow velocity and relative current to.In conjunction with electronic compass, be not difficult to synthesize the true flow direction.
Obviously, the present invention is miniaturization and measurement mechanism cheaply, and it is rational in infrastructure, easy to use, and measurement flow rate flows to simultaneously, has improved the intelligent and economy of flow measurement sensor etc. effectively.

Embodiment
As Fig. 1, Fig. 2, the present invention includes an impeller flow measurement sensor 1, it is characterized in that it also comprises connected another impeller flow measurement sensor 2, and the central axis of these two impeller flow measurement sensors 1,2 is mutually orthogonal all-in-one-pieces.Two above-mentioned impeller flow measurement sensors 1,2 utilize prior art can record two mutually orthogonal velocity vectors respectively, two mutually orthogonal velocity vectors also being not difficult to utilize existing data acquisition processing device 3 to record synthesize true flow velocity and relative current to.
Measuring method is: at first two these devices of the mutually orthogonal all-in-one-piece of impeller flow measurement sensor are put into the flow field, just obtain two mutually orthogonal velocity vectors respectively, it is synthetic to rely on data acquisition processing device to carry out vector then, just can calculate or demonstrate true flow velocity and relative current to.In conjunction with electronic compass, be not difficult to synthesize the true flow direction.Its principle as shown in Figure 3, wherein
Be the velocity vector of two flow sensor measures in the flow field of measuring,
Be the synthetic velocity vector of vector,
It is the true velocity vector in flow field.
Using method of the present invention: at first this device is put into wind field or current, can measure two mutually orthogonal velocity vectors in the flow field respectively; Rely on data acquisition processing device again, can obtain true flow velocity and relative current to.If in conjunction with electronic compass, be not difficult to synthesize the true flow direction.
When above-mentioned two mutually orthogonal all-in-one-piece devices of impeller flow measurement sensor are put into the flow field, need not to consider again that two impeller flow measurement sensors of split put into the locational particular requirement in flow field.
