Smart water meter features

Photoelectric direct reading is the collection of relevant information on the secondary measuring element wheel to determine the reading of the character wheel. Photoelectric direct reading is more difficult due to the application of sensor components, complicated hardware circuits, high process requirements, and high cost. The mechanical direct reading mainly obtains the coded information through the direct contact of the pressure spring to the code wheel, thereby determining the corresponding indication position. Although this method is lower in cost than the former, due to the influence of the material of the reed and the processing technology, there are problems such as poor reliability, large mechanical damping (large flow rate of water meter), and improvement in mass production processability. In summary, the base table of the smart water meter at present is characterized by diversity in metering and sensing technology. Due to the limitations of current technology and process technology, various methods have not formed outstanding technologies. Advantages and industrial advantages.
