[Chinese instrument network meter patent] creative limit, instrumentation invention. Today we introduce a national invention-issued patent - an ultrasonic water meter with mechanical readings. The patent was applied for by Lianyungang Tengyue Electronic Technology Co., Ltd., and it was authorized on February 8, 2017.
Description of the invention The utility model relates to a water metering device, in particular to an ultrasonic water meter with a mechanical reading.
BACKGROUND OF THE INVENTION At present, ultrasonic water meters only contain electronic readings. Many water companies are accustomed to the mechanical readings of past water meters and are somewhat repulsive to ultrasonic water meters, which is not conducive to market promotion. In addition, because the ultrasonic water meter belongs to the all-electronic water meter, the data is stored in the memory. When the memory is damaged, the water consumption cannot be read and the historical data will disappear, causing unnecessary losses.
Summary of the Invention The technical problem to be solved by the utility model is to address the deficiencies of the prior art and propose an ultrasonic water meter with a clearer and simpler reading and mechanical reading.
The technical problem to be solved by the utility model is achieved through the following technical solutions. An ultrasonic water meter with mechanical readings includes an ultrasonic tube section and a meter head, characterized in that the meter head is provided with a table connected to the ultrasonic tube section. Shell, case cover with a cover, the case is equipped with a main control board, mechanical counter, LCD screen and battery pack; the corresponding cover on the cover with a mechanical count display window and LCD screen display; mechanical counter connection with steps Into the motor, the stepper motor is electrically connected with the main control board, and the stepper motor receives the quantitative pulse from the main control board to realize the synchronous display of the mechanical counter and the liquid crystal screen.
The figure is a schematic diagram of the structure of the utility model
The watch head is provided with a watchcase connected to the ultrasonic tube section, a watch cover is provided with a watch cover, a main control board, a mechanical counter 5, a liquid crystal screen 1 and a battery pack are arranged in the watch case, and the watch case and the watch cover are arranged between Sealed by O-type seal. Correspondingly, a mechanical count display window and a liquid crystal display window are provided on the cover of the watch; a stepper motor 4 is connected to the mechanical counter 5; the stepper motor 4 and the main control board 2 are electrically connected through the data line 3; and the stepper motor 4 receives the call from the master. The quantitative pulse of the control board 2 realizes the synchronous display of the mechanical counter and the liquid crystal screen.
When the water consumption reaches the set value (for example, 1m3), the main control board will send a certain amount of pulses to the stepper motor of the mechanical counter to make the mechanical counter run, so that the electronic and mechanical readings can be displayed in the ultrasonic water meter. The function. Mechanical readings can also be used as historical data when the memory is damaged. Transparent covers are provided at the mechanical count display window and the LCD display window. The transparent cover is made of organic glass.
The technical problems to be solved by the utility model can also be further realized by the following technical solutions. The case and the cover are sealed by an O-type seal. Transparent covers are provided at the mechanical count display window and the LCD display window.
Compared with the prior art, the utility model is a kind of water meter which adopts the time difference of the ultrasonic wave in the countercurrent propagation of the water flowing in the countercurrent flow, and analyzes and processes the flow rate of the water to further accumulate the flow rate of the water. In addition to the electronic readings, there are mechanical readings. The user's reading is clearer and simpler, without having to flip the LCD screen to find the relevant reading.
