Referring to fig. 1, a schematic structural diagram of a flow rate detection device according to an embodiment of the present application is shown, and referring to fig. 2, an exploded structural diagram of a flow rate detection device according to an embodiment of the present application is shown. As shown in fig. 1 and fig. 2, a flow rate detecting device provided in the embodiments of the present application is used for measuring a flow rate of a fluid in a pipeline, where the fluid may be a liquid, a gas, or a small solid particle. The flow detection device can measure the flow of different fluids in the pipeline from the outer side of the pipeline, so that the actual monitoring requirement is met.
In this embodiment of the application, the flow detection apparatus may specifically include: the device comprises a first electrode plate 10, a second electrode plate 20, a voltage measuring element and a processor, wherein the first electrode plate 10 and the second electrode plate 20 are oppositely arranged and are used for being clamped outside a pipeline, when the first electrode plate 10 and the second electrode plate 20 are electrified, the first electrode plate 10 and the second electrode plate 20 can form a capacitor, when fluid flows through a region between the first electrode plate 10 and the second electrode plate 20, a dielectric medium between the first electrode plate 10 and the second electrode plate 20 can be changed, and therefore voltage change between the first electrode plate 10 and the second electrode plate 20 is caused, and flow of the fluid can be calculated by measuring the voltage.
Specifically, the voltage measuring element in the embodiment of the present application is electrically connected to the first electrode plate 10 and the second electrode plate 20, and the first electrode plate 10 and the second electrode plate 20 need to be pre-charged before use, so that an initial voltage U is provided between the first electrode plate 10 and the second electrode plate 200For the convenience of subsequent calculation, the initial voltage U0May be a preset voltage.
The relationship between capacitance and voltage is known as:
wherein C is a capacitor, q is an electric quantity, and U is a voltage.
As can be seen from equation (1), in the case where the dielectric between the first electrode plate 10 and the second electrode plate 20 is not changed, for example, when the dielectric is air, the corresponding capacitance is the initial capacitance C0Initial voltage U0The corresponding electric quantity is q0＝C0U0. Due to the initial voltage U0To a predetermined voltage, an electric quantity q0Namely the preset electric quantity.
Will have an electric quantity q0The first electrode plate 10 and the second electrode plate 20 are clamped outside the pipeline, at this time, when fluid flows through the pipeline, the dielectric medium between the first electrode plate 10 and the second electrode plate 20 changes, and according to a calculation formula of capacitance:
wherein, is a dielectric constant, a is a relative area of the first electrode plate 10 and the second electrode plate 20, and d is a distance between the first electrode plate 10 and the second electrode plate 20.
As can be seen from equation (2), when the dielectric medium changes, the dielectric constant changes, and for the flow rate detection device in the embodiment of the present application, the relative positions of the first electrode plate 10 and the second electrode plate 20 are fixed, so a and d are not changed, and therefore, when the dielectric constant changes, the capacitance C changes.
That is, when the first electrode plate 10 and the second electrode plate 20 are clamped outside the pipe and fluid flows through the pipe, the capacitance C between the first electrode plate 10 and the second electrode plate 20 changes. And due to the electric quantity q on the first electrode plate 10 and the second electrode plate 200Is fixed, a change in capacitance C causes a voltage change.
Accordingly, it is possible to measure the detection voltage U between the first electrode plate 10 and the second electrode plate 201And according to the initial voltage U0And detecting the voltage U1The difference between Δ U, the flow Q of the fluid can be estimated. Wherein the difference value Δ U is a variation value of the voltage between the first electrode plate 10 and the second electrode plate 20.
