The beneficial effects of the utility model are: after having adopted said structure, measure changes of magnetic field by signal converter, the signal of measurement is delivered to intelligent processor afterwards by signal electrode; 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, measuring guide; 2, signal electrode; 3, protecting sheathing; 4, field coil; 5, signal converter; 6, intelligent processor; 7, conduit; 8, float; 9, height measuring gauge; 10, insulation lining.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
The accurate electromagnetic flowmeter of a kind of measurement as shown in Figure 1, comprise measuring guide 1, in the outside of measuring guide 1, be provided with field coil 4, in the outside of field coil 4, be provided with protecting sheathing 3, described measuring guide 1 is provided with signal electrode 2, signal electrode 2 is connected with signal converter 5, signal converter 5 connects intelligent processor 6, described measuring guide 1 outside is provided with a conduit 7, two joints of this conduit 7 are connected to highs and lows radially of measuring guide 1 and are communicated with measuring guide 1, described conduit 7 inside are provided with a float 8, described float 8 and conduit 7 are provided with for measuring the height measuring gauge 9 of float 8 height, height measuring gauge 9 is connected with intelligent processor 6, described conduit 7 center sections and measuring guide 1 is axially vertical, and two joints of conduit 7 and the junction of measuring guide 1 tilt along water (flow) direction, described angle of inclination is 15 ° or 30 °, the inwall of described measuring guide 1 is provided with insulation lining 10.
First, field coil 4 energisings make the space in measuring guide 1 be positioned at magnetic field, conducting liquid is answered line from flowing through cutting magnetic induction in measuring guide 1, signal electrode 2 senses that the variation of lines of magnetic induction passes to signal converter 5 by this variation by cable, signal converter 5 strengthens the signal received and convert unified standard signal to and passes to intelligent processor 6, simultaneously, conducting liquid also can flow in conduit 7, liquid-driving float 8 in conduit 7 rises, if conducting liquid is non-full pipe in measuring guide 1, the height that float 8 rises differs, by height measuring gauge 9, measure the height of float 8, altitude signal is passed to intelligent processor 6, intelligent processor 6 is by after lines of magnetic induction variable signal and altitude signal overall treatment, can draw real flow value, total is simple, easy to operate.
Height measuring gauge 9 can by conduit 7 and float 8 respectively signalization transceiver determine its height.In conduit 7 inside of placing float 8, have and can prevent that float 8 from entering the boss of measuring guide 1.
