Abstract
The utility model discloses a magnetic control water meter sensor. A dry spring tube 1 of the sensor is arranged on a viewing windowpane 2 or in the viewing windowpane 2 of a water meter with a shell 4, the viewing windowpane 2 and a pointer 5. The magnetic control water meter sensor is characterized in that an attached magnet 6 is arranged on the dry spring tube 1; a shielding cover 7 is arranged on the attached magnet 6 and the dry spring tube 1; a diameter position on the rotary disc pointer 5 of the water meter is oppositely provided with two magnets 3 with difference polarity, wherein, one magnet is provided with an N pole and the other is provided with an S pole. The utility model has the advantages that rolling error is eliminated by utilizing magnetic force to keep the state of the dry spring tube; a software program only processes one signal of the dry spring tube; the procedure is simplified; the universality is enhanced.
Description
The utility model relates to the instrument of measuring the water yield, exactly is a kind of magnet controlled sensor of water meter.
The water meter of prior art or the sensor element of water meter are got through the hole sensor are put into the method for showing on the glass window of watchcase or table, realize the moving metering of order.
There is the calibration inconvenience in these water meters, influence service precision and seal shortcomings such as unreliable.At the shortcoming of above existence, the applicant improves, and has proposed the patent No. and be 96243802.2 and 99206865.7 Chinese patent (application), has improved the deficiency of above existence.In normal water supply project, use, have effect preferably.Also overcome minimum current or substantially anhydrous stream and the use occasion than minor swing of the water yield has only been arranged.But because it uses two tongue tube pickoff signals, hardware and software handling procedure more complicated, the independent program of necessary design could be exchanged with present widely used intelligence instrument and be general, in order to improve the versatility of sensor of water meter, be beneficial to large scale application, proposed the purpose of this utility model.
The purpose of this utility model is in order to overcome the deficiency that prior art exists, a kind of magnet controlled sensor of water meter to be provided.
The purpose of this utility model realizes according to structure described below.A kind of magnet controlled sensor of water meter, the tongue tube 1 of this sensor is arranged on the viewing glass 2 of the water meter with housing 4 and viewing glass 2 and pointer 5 or its inside, it is characterized in that on tongue tube 1, being provided with an attachment magnets 6, have a radome 7 in attachment magnets 6 with above the tongue tube 1, the diametrical position on the rotating disk pointer 5 of water meter is oppositely arranged one and has the N utmost point and the induced magnet 3 with two opposed polarities of the S utmost point.
Advantage of the present utility model is removed replacing that does not influence watch core and the adjustment that has in 96243802.2 and 99206865.7, does not influence the sealing of water meter and uses measuring accuracy and compressive strength, is particularly suitable for the water meter of wet type and other kind.In use as long as on existing water meter, change glass of the present utility model and magnet be set, outside the advantage that can normally use in the inductive means tongue tube position of pointer and sensor.Also have accurate measurement, be not subjected to the characteristics of indicator of water gauge parts less than the influence of the swing of half cycle or fluctuation.Have more the characteristics of the simple and reliable and highly versatile of software design.
The following drawings explanation, accompanying drawing is the water meter diagrammatic cross-section of magnet controlled sensor of water meter of the present utility model.The sequence number of each parts in the accompanying drawings is: 1, tongue tube, 2, viewing glass, 3, magnet, 4, water meter case, 5, indicator of water gauge, 6, attachment magnets, 7 radomes.
Below in conjunction with the embodiment in the accompanying drawing, describe structure of the present utility model and use in detail.With reference to accompanying drawing, this magnet controlled sensor of water meter, the tongue tube 1 of this sensor is arranged on the viewing glass 2 of the water meter with housing 4 and viewing glass 2 and pointer 5 or its inside, it is characterized in that on tongue tube 1, being provided with an attachment magnets 6, have a radome 7 in attachment magnets 6 with above the tongue tube 1, the diametrical position on the rotating disk pointer 5 of water meter is oppositely arranged one and has the N utmost point and the magnet 3 with two opposed polarities of the S utmost point.Generally speaking, in the time spent of doing that is subjected to magnetic field force, two contact is contact just in reed pipe, and magnetic field force is not responded to and when acting on thereon, two contacts disconnect at once.A N utmost point is set and S utmost point magnet 6 back tongue tubes have just had the automatic maintenance function of conducting or off-state with induction end to corresponding position like this on tongue tube 1, if promptly there is not external induction, tongue tube just keeps its conducting or off-state always.At this moment, if the pointer of water meter rotates, then the magnet on it also rotates thereupon together, when the magnet on the pointer 53 goes to the induction end of tongue tube 1, because this end attachment magnets is the S utmost point, identical with the polarity on the pointer 5, thereby repelled, the contact disconnects, after the S utmost point transfers, the maintenance effect that the tongue tube 1 of this moment has attachment magnets, its contact still keeps off-state, when this process goes to induction end up to the N of the pointer utmost point, inhale mutually with the S utmost point of induction end, make the outstanding conducting in contact of tongue tube, after the N utmost point was rotated further and leaves, the contact still kept conducting, when the next S utmost point goes back to again, the contact disconnects again, goes round and begins again successively, forms continuous induced signal.Like this, tongue tube only rotates greater than half-turn at pointer could realize that one logical one is disconnected, thereby has eliminated effectively because of the pointer influence error that swings back and forth and cause among a small circle.The effect of radome 7 is to be used to the interference that prevents that external magnetic field from causing.So only, just can finish the work of two sensors in the past, and effectively reliable with a sensor, avoided since two tongue tubes must processing software program, improved the versatility of sensor of water meter on intelligence instrument.
