Abstract
The utility model relates to a pulse signal device capable of determining the water flowing direction in a water meter, which is characterized in that the positions of an axial center O of a magnetic pointer 3 and magneto sensors A and B are arranged in an isosceles triangle, and the waist length OA is equal to the waist length OB which is equal to 6 to 19 mm. The utility model has the advantages that the water flowing direction in the water meter can be judged, misoperation generated by the shake of the magnetic pointer can also be avoided, measuring reliability is improved, and the device is also suitable for being used for a gas meter and an electric meter.
Description
The utility model relates to a kind of electromagnetic flowmeter that passes through the fluid flow of instrument continuously, particularly a kind of pulse signal device of decidable water meter water (flow) direction measured.
Existing water meter pulse signal device can only measure under conventional water (flow) direction situation can't be found by the flow of water meter and steal the water phenomenon during metering water meter upside-down mounting, the wet water-meter pulse telltale that provides as Chinese patent ZL97245995.2, it contains a circuit board that is contained on the transparent outer cover, often open magneto sensor and a normally closed magneto sensor is installed on the circuit board respectively for one, pulse signal is exported by extension line, and the rotating shaft of magnetic pointer is provided with magnet steel.The defective of this pulse signal device is to judge that the magnetic pointer is just to change or reverse, so steal the water phenomenon in the time of can not in time finding the water meter upside-down mounting, and when magnetic pointer and magneto sensor are in critical localisation, owing to the magnetic pointer is shaken, can produce misoperation, functional reliability is relatively poor.
The purpose of this utility model is to provide a kind of pulse signal device of decidable water meter water (flow) direction, and it can in time find to utilize the upside-down mounting water meter to steal the phenomenon of water, accurately measures discharge, for microcomputer collection and network management.
A kind of pulse signal device of decidable water meter water (flow) direction, the inner cap 1 that comprises water meter, meter reading index dial 2, magnetic pointer 3, circuit board 4, magnet 5, be positioned at the magneto sensor A and the B in the magnet outside, wherein magnet (5) is connected as a single entity with the rotating shaft of magnetic pointer (3), the axle center O that it is characterized in that magnetic pointer 3 is the isosceles triangle layout with magneto sensor A and B, the isosceles triangle apex angle is 10 °～80 °, the axle center O of magnetic pointer 3 and magneto sensor apart from OA=OB=6～19mm, inner cap 1 is made by transparent engineering plastics, has a groove 1a who is used to arrange the pulse signal transmission line on it, and this groove 1a is 60 ° in projection on the rising pipe surface level and the angle between the rising pipe.Described magneto sensor is a tongue tube, perhaps hall device, and perhaps mistor, circuit board 4 adopts conventional structures, and the electromagnetic structure of this pulse signal device also is suitable for using on gas meter and ammeter.
With prior art relatively, the utility model has the advantages that and to judge the water meter water (flow) direction, identification magnetic pointer is just to change or reverse, the mechanical rotation reading and the pulse signal output that guarantee water meter are synchronous, overcome the misoperation that the shake of magnetic pointer produces simultaneously, improve functional reliability, be beneficial to the network management of realizing user's water consumption.The electromagnetic structure of this device also is applicable to gas meter and ammeter.
Fig. 1 is the pulse signal device structural representation of decidable water meter water (flow) direction.
Fig. 2 is the magnetic element arrangenent diagram of this device.
The pulse signal sequential chart that magneto sensor A and B produced when Fig. 3 turned clockwise for the magnetic pointer.
The pulse signal sequential chart that magneto sensor A and B produced when Fig. 4 was the rotation of magnetic pointer inhour.
Embodiment:
A kind of pulse signal device of decidable water meter water (flow) direction, mounting circuit boards 4 and magneto sensor A and B on the inner cap 1 of rotor water gauge, the axle center of setting 0.01 ton of magnetic pointer 3 is O, this axle center O and magneto sensor apart from OA=OB=10.5mm, apex angle is 60 °, the pulse signal transmission line is arranged in the groove 1a, when 0.01 ton of magnetic pointer turns clockwise, revolution moves a week, the sequential of its pulse signal output is 11-01-00-10-11, if pointer is rotated counterclockwise, then a moving week of revolution, the sequential of its pulse signal output is 11-10-00-01-11, sequential difference according to the output pulse signal existence, can judge easily that thus the magnetic pointer is just to change or reverse, promptly water meter is along dress or upside-down mounting, judges whether surreptitiously water phenomenon takes place.
Claims (3)
