Abstract
The invention discloses a water meter capable of rapidly measuring flow, which comprises a rotating part and a measuring circuit and is characterized in that a permanent magnet is arranged at the rotating part; the measuring circuit comprises a magnetic switch and a timing measuring element; wherein the magnetic switch is located on the motion trajectory of the permanent magnet. The measuring method of the water meter capable of rapidly measuring the flow comprises the following steps of: (1) rotating the permanent magnet at the rotating part to a position of the magnetic switch so as to ensure that the magnetic switch is closed and the timing measuring element starts timing; (2) rotating the permanent magnet at the rotating part to leave the position of the magnetic switch so as to ensure that the magnetic switch is off and the timing measuring element stops timing; and (3) figuring out the rotate speed of the rotating part according to the closing time of the magnetic switch, which is recorded by the timing element and figuring out the instantaneous flow on the basis that the representative water quantity when the rotating part is rotated by a circle is fixed. According to the invention, the instantaneous flow can be measured when the rotating part of the water meter is rotated by a circle, therefore, the rapid measurement of the flow can be realized.
Description
Technical field
The present invention relates to the tolerance field, particularly a kind of water meter of quick measurement flow and measuring method thereof.
Background technology
The method that water meter commonly used is at present measured flow is that the rotation number of turns of the water meter rotatable parts in the unit interval is calculated mean flow rate; The normal structure that adopts is that rotatable parts are half black half white dial plates, through photoelectric sensor reflected impulse counting is realized flow measurement.
The accuracy of this mode in order to measure avoided because the error that the difference of a pulse produces, thus the time must put very longly, this time that has just caused measuring must lengthen, and causes the low of efficient; Confirm instantaneous delivery fast and accurately for pursuing, then must reduce the test duration, the phenomenon that causes losing pulse has influenced its accuracy, and the fluctuations in discharge of reaction is just very big, unstable, poor accuracy.
Summary of the invention
The object of the invention is to the defective of prior art a kind of water meter and measuring method thereof of fast, accurately measuring flow to be provided.
The present invention adopts following technical scheme for realizing above-mentioned purpose:
A kind of water meter of quick measurement flow comprises rotatable parts and metering circuit, it is characterized in that: said rotatable parts are provided with permanent magnetic iron; Said tachometer circuit comprises magnetic switch and timing measuring element, and said magnetic switch is positioned on the movement locus of said permanent magnetic iron.
The measuring method of the water meter of the described quick measurement flow of a kind of claim 1 may further comprise the steps:
(1) permanent magnetic iron on the said rotatable parts turns to the magnetic switch position, said magnetic switch adhesive, and the timing measuring element picks up counting;
(2) permanent magnetic iron on the said rotatable parts leaves the magnetic switch position, and said magnetic switch breaks off, and the timing measuring element stops timing;
(3) calculate the rotating speed of rotatable parts pickup time according to the magnetic switch that timing element write down, fix because rotatable parts rotate the water yield of week representative, thereby calculate instantaneous delivery.
Water meter rotatable parts of the present invention rotate can measure instantaneous delivery once enclosing, and can realize the quick measurement of flow.
Description of drawings
Fig. 1 is the invention synoptic diagram;
Among the figure, the 1-rotatable parts; The 2-permanent magnetic iron; The 3-magnetic switch; 4-timing measuring element.
Embodiment
The water meter of a kind of quick measurement flow as shown in Figure 1 comprises rotatable parts 1 and metering circuit, and said rotatable parts 1 are provided with permanent magnetic iron 2; Said tachometer circuit comprises magnetic switch 3 and timing measuring element 4, and said magnetic switch 3 is positioned on the movement locus of said permanent magnetic iron 2.
The characteristic of magnetic switch be as magnetic field near the time can adhesive, thereby realize switching function; When rotatable parts when central shaft rotatablely moves, permanent magnetic iron also can move in a circle along concentric, then periodically through magnetic switch, thereby periodically realizes the conducting metering circuit.
This moment, the timing measuring element was measured the time of magnetic switch adhesive, and the permanent magnetic iron rotating speed is also fast when flow rate of water flow is fast, and will lack pickup time; Otherwise pickup time can be longer; Be directly proportional with the rotatable parts rotating speed pickup time.
Because it is (this has the decision of water meter build-in attribute) of fixing that rotatable parts rotate the water yield of week representative, therefore can be through measuring the rotating speed of realizing calculating rotatable parts pickup time of magnetic switch, that is the rotating speed of water meter.Thereby realized moving and to have realized the quick measuring method that tests the speed a week at the water meter rotatable parts.
