Abstract
The utility model discloses an electronic water meter belongs to the device of the fluidic flow of measuring the continuous through instrument. The zero-power consumption magnetic-sensing probe consists of a shell, an impeller in the shell, a permanent magnet arranged on the impeller and a zero-power consumption magnetic-sensing probe which is fixed on the shell and connected with a flow display through a lead, wherein the distance between the permanent magnet and the magnetic-sensing probe is 2-30 mm. Compared with the prior art, the utility model discloses do not need the power when using, simple structure, the measurement is accurate, low cost, and the management is convenient.
Description
The utility model relates to a kind of device of measuring the flow of the fluid that passes through instrument continuously, particularly a kind of electronic water meter.
Conventional water meter be water by the time impeller of getting excited, gears that impeller shaft drives several band pointers are realized measuring.To go to check meter to each user when using this water meter counting to charge, manage very inconvenient.Chinese patent CN2212777y discloses a kind of electronic water meter, has mainly solved the problem that common water meter inconvenience is checked meter; But this electronic water meter must be powered to sensing element in use, and this has just brought new trouble, if use alternating current need use DC voltage-stablized source apparatus, and complex structure, cost improves, and water can't accurate counting during power failure; Have life problems again with battery, the user's there is no telling when electricity of battery exhausts, so in fact this electronic water meter can't reach practical purpose.
The purpose of this utility model is to overcome above-mentioned water meter structure complexity, management inconvenience, measures shortcomings such as inaccurate, provides a kind of simple in structure, accurate measurement, with low cost, electronic water meter easy to use.
The purpose of this utility model reaches like this, a kind of electronic water meter, comprise the impeller in housing and the housing, it is characterized in that, permanent magnet is arranged on the impeller, also have the contactless magnetosensitive probe of the zero power consumption that is connected with flow indicator 6 by the potential pulse output line on the housing, and the minor increment between permanent magnet and the magnetosensitive probe is 2 to 30 millimeters.
Owing to adopted the zero contactless magneto sensor of power consumption to pop one's head in, do not need during use to make the utility model simple in structure to its power supply, cost reduces; The metering of can not transmission signals when simultaneously also having avoided non-transformer and causing is inaccurate; When current are equipped with the wheel rotation of permanent magnet by the electronic water meter impulsion, the magnetosensitive probe produces and flow correspondent voltage pulse signal, this signal is transported to the counting Displaying Meter and is realized counting purpose through lead, and use and management is very convenient, can reach goal of the invention fully.
The utility model also can be described further in conjunction with the embodiments.
Figure of description is the structural representation of a kind of embodiment of the present utility model.It is by housing 3 and interior impeller 4 thereof, and the permanent magnet 5 that is contained on the impeller 4 is formed with the contactless magnetosensitive probe 1 of the zero power consumption that is connected with the flow indicator 6 of concentrating setting by voltage output line 2.Select for use the surface magnetic flux density (BS) on direction of easy axis to be the special permanent magnet of 60-400 milli, and make the minor increment (d) between permanent magnet and the magnetosensitive probe be the 2-30 millimeter.According to the inventor's experience, surface magnetic flux density (BS) and minor increment (d) permanent magnet and magnetosensitive probe between during for the following table institute train value exportable the utility model normal working voltage pulse of permanent magnet on direction of easy axis:
As long as the surface magnetic flux density (BS) of permanent magnet is special at the 60-400 milli, the minor increment (d) between permanent magnet and the magnetosensitive probe all can realize goal of the invention by appropriate combination in the 2-30 millimeter, and concrete array mode is too numerous to enumerate.In the use, when current by electronic water meter, when the impeller of permanent magnet was equipped with in impulsion, zero power consumption is contactless, and the magnetosensitive probe just produced voltage pulse signal and transport to through lead and to concentrate the flow indicator that is provided with and to show, write down its flow.
