Abstract
The utility model discloses an imaging electromagnetic flowmeter. The structure of the imaging electromagnetic flowmeter is mainly composed of measuring electrodes, an excitation device, an amplifying device and a processor. The utility model is characterized in that the flowmeter is provided with more than two measuring electrodes and the amplifying device, and the amplifying device is matched with the measuring electrodes; the processor which is connected with the back end of the amplifying device is an imaging-type processor. The utility model conquers the disadvantages of the product in the prior art that the installation is inconvenient, the measurement precision is low, etc. The utility model has the characteristics of high measuring precision, wide installation condition, no straight-pipe segment need, fluid information display, etc. The utility model can be widely used for the measurement of liquid, suspended solid, slurry material and other fluids of definite electric conductivity.
Description
The utility model relates to a kind of by apply the electromagnetic flowmeter that its flow is measured in magnetic field to fluid.
Before the utility model was made, existing electromagnetic flowmeter all adopted the bipolar electrode detection mode.This mode measurement flow rate preferably is axisymmetric fluid flow, and when flow velocity off-axis symmetry, measuring error will be unable to estimate.In order to guarantee the axial symmetry of flow velocity, the flowmeter front end needs sufficiently long straight length, and this brings certain difficulty for the installation of flowmeter, and may be difficult to sometimes realize in commercial Application.
On the other hand, along with science and technology development, scientific research and engineering experiment all press for understands the fluid internal information.Need under the situation of not destroying, do not disturb fluid to flow, to obtain the two dimension or the distributed in three dimensions information of pipeline and device interior fluid.Engineering practice proposes discharge of sewage detection as also needs under the situation of the continuous fouling of inner-walls of duct can continue to detect, and existing flowmeter can't satisfy these requirements.
The purpose of this utility model provides a kind of imaging electromagnetic flow rate meter of novel structure.This flowmeter is not subjected to whether flow velocity is axisymmetric restriction when installing, even measuring accuracy is also higher under the minimum velocity condition, and it is wide to have a mounting condition, need not straight length, can show characteristics such as fluid information.
The purpose of this utility model reaches by following technical proposals: a kind of imaging electromagnetic flow rate meter, comprise potential electrode, excitation unit, multiplying arrangement and processor, its structural feature is: the multiplying arrangement that this flowmeter has the potential electrode more than two and is complementary with it, the processor that the multiplying arrangement rear end connects is the imaging type processor.
The utility model in the specific implementation, the multiplying arrangement that has eight potential electrode on the flowmeter and be complementary with it.
The utility model compared with prior art, the utility model is owing to improve on potential electrode quantity, multiplying arrangement structure and processor, make the velocity field of this flowmeter energy convection cell carry out the imaging demonstration, have the measuring accuracy height, mounting condition is wide, need not straight length, the fluid information of demonstration characteristics are arranged.
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:
Accompanying drawing is the utility model example structure synoptic diagram.
Referring to accompanying drawing.This imaging type flowmeter is made up of measuring tube 3, detecting electrode 1, field coil 2, multiplying arrangement 5, processor 6 and display 7 in the accompanying drawings.1a-1h is a detecting electrode, and 5 is the electrode detection multiplying arrangement, is made up of prestage 4a-4g, high-speed a/d 5a.6 is arithmetic processor, is made up of 486 above CPU, and 7 is image display.
