Description
Technical field
The invention belongs to water meter field, particularly a kind of electronic type drinking water meter.
Background technology
Present domestic meter generally adopts mechanical transmission-type water meter, water consumption is shown with the structure of pointer or character wheel counting, owing to adopting a large amount of transmission gears, when low discharge, the kinetic energy of current is difficult to the inertia and the resistance that overcome water meter mechanical part, thus causes flow not count and measure inaccurate phenomenon.The mechanical component of water meter inside use simultaneously, due to long-term rotation wearing and tearing, can make the accuracy of metering by very large impact.And the intellectual water meter used now,, at the reading dial pointer of water meter or certain position of gear set, sensing element is installed, convert the mechanical reading of original water gauge to electrical signal data, then carry out gathering, computing, transmission, also do not depart from the traditional mode of original mechanical water meter, do not tackle the problem at its root.
Summary of the invention
The object of the present invention is to provide a kind of magnetic impulse type electronic water meter of electronic measurement.
The present invention is achieved in that
Magnetic impulse type electronic water meter, mainly comprises table body, table cover, is set to epicoele and cavity of resorption, is provided with aquaporin in cavity of resorption, cross in aquaporin and rotating shaft is provided with impeller, it is characterized in that: the rotating shaft of described impeller is provided with diametrical magnetization magnet piece in table body; Be provided with the angle Hall element with described magnet piece magnetic coupling in described epicoele, this angle Hall element is by single-chip microcomputer connecting fluid crystal display.
Described angle Hall element and single-chip microcomputer are arranged on circuit boards, and circuit board is arranged in an electrical box.Described liquid crystal display is arranged in table cover.
After the present invention adopts said structure, magnetic-pulse electronic measurement mode is utilized to realize the metering of water meter precision, improve measuring accuracy, extend the serviceable life of water meter, have that structure is simple, easy to use, practical, cost is low, reliability high, water meter measurement and the control of Drinking Water Industry or family can be widely used in.
