However, this method generally uses a gear to determine the value of the character wheel, because a disc has 360°, and it is impossible to accurately determine the value of its carry state simply from a gear, resulting in inaccurate readings, which may be accumulated over time. lead to bigger mistakes

Embodiment Construction
[0013] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes several character wheels 1, and the character wheel 1 is provided with a first ring 2 and a second ring 3 sequentially from the inside to the outside, half of the area on the first ring 2 is a blank area 4, and the other half area is a shadow area 5. On the second ring 3 corresponding to the blank area 4 of the first ring 2, three blank areas 4 and two shadow areas 5 are evenly spaced, and the second ring 3 corresponding to the shadow area 5 of the first ring 2 Two blank areas 4 and three shaded areas 5 are evenly spaced on the two rings 3 . Five first sensors 6 are uniformly arranged on the side of the shaded area 5 of the first ring 2, and one is arranged in the middle of the side of a shadowed area 5 of the second ring 3 corresponding to the shadowed area 5 of the first ring 2. The second sensor 7 is provided with a third sensor 8 at a central angle of 54° in the...

The invention relates to a water meter, in particularly to a high reliability correlation type direct reading liquid seal water meter. The water meter comprises a plurality of character wheels, and each character wheel is sequentially provided with a first circular ring and a second circular ring from inside to outside. The water meter is characterized in that half area of the first circular ring is a blank area, the other half area is a shadow area, the position, corresponding to the blank area of the first circular ring, of the second circular ring is provided with three blank areas and two shadow areas at equal intervals, and the position, corresponding to the shadow area of the first circular ring, of the second circular ring is provided with two blank areas and three shadow areas at equal intervals. The water meter has the advantages that partition meter reading is achieved, two-level error detection is achieved, the water meter is high in reading accuracy rate, simple in structure and convenient to manufacture and install, and great contribution is made to metering of the water flow rate.
Description
(1) Technical field [0001] The invention relates to a water meter, in particular to a highly reliable through-beam direct-reading liquid-sealed water meter. (2) Background technology [0002] With the current technology, gas, water, and electricity meters all have the function of direct reading and remote transmission. It is no longer necessary for meter readers to go door-to-door to manually read meters. Only the sensors installed on the meters can be remotely transmitted to the computer. Meters usually used to measure the flow of gas, liquid, electricity, etc., its working principle is to pass gas, liquid, and dielectric through the flow detection device in the instrument, the flow detection device drives the transmission device, and then the transmission device drives the reading disc to rotate, When the character code is set on the reading disc, the rotation amount on the reading disc is reflected by the character code. However, this method generally uses a gear to dete...
