Description
Technical field
The present invention relates to a kind of flow measuring meter in machinery industry, especially relate to the accurate electromagnetic flowmeter of a kind of measurement.
Background technology
Electromagnetic flowmeter is according to Faraday's electromagnetic induction law, to carry out the flowmeter of flow measurement.The advantage of electromagnetic flowmeter is that crushing is minimum, measurable flow weight range is large, at conducting liquid, magnetic field is set around, the conducting liquid cutting magnetic induction in magnetic field that flows is answered line, produce the induced potential proportional with flow rate of liquid, its induced potential signal is directly measured by the signal electrode directly contacting with liquid, by cable, pass to converter, carry out afterwards processor and carry out signal processing, realize the demonstration of transient liquid flow, integrated flux and the Communication Control between data on flows and computer system.At present, the flowmeter often using is the in the situation that of full packages, it is very accurate to measure, when fluid flow is at non-full pipe in the situation that, just cannot measure accurate flow value, and for the situation of non-full pipe, only have a small amount of flowmeter to select at present, complicated but its structure is handed over, be difficult for processing and assembling, cost is higher.
Summary of the invention
Technical matters to be solved by this invention is to provide the accurate electromagnetic flowmeter of a kind of measurement, and it can accurately measure under the state of non-full pipe, and it is simple in structure, convenient and swift aspect processing and assembling, reduces its production cost.
The present invention solves the technical scheme that its technical matters takes: the accurate electromagnetic flowmeter of a kind of measurement, comprise measuring guide, outside in measuring guide is provided with field coil, outside at field coil is provided with protecting sheathing, described measuring guide is provided with signal electrode, signal electrode is connected with signal converter, signal converter connects intelligent processor, described measuring guide outside is provided with a conduit, two joints of this conduit are connected to highs and lows radially of measuring guide and are communicated with measuring guide, described catheter interior is provided with a float, described float and conduit are provided with for measuring the height measuring gauge of float height, height measuring gauge is connected with intelligent processor.
Further concrete, described conduit center section is axially vertical with measuring guide, and two joints of conduit and the junction of measuring guide tilt along water (flow) direction.
Further concrete, described angle of inclination is 15 ° or 30 °.
Further concrete, the inwall of described measuring guide is provided with insulation lining.
The invention has the beneficial effects as follows: after having adopted said structure, by signal electrode, measure changes of magnetic field and by signal converter, the signal of measurement is delivered to intelligent processor afterwards; The height of measuring float by height measuring gauge passes to intelligent processor by altitude signal; Intelligent processor, by the magnetic field variation signal receiving and altitude signal overall treatment, draws accurate flow information value.
