1、 Reading principle

Our company's photoelectric direct reading sensor adopts the principle of photoelectric transmission encoder. Each character wheel is used as a code wheel, and five infrared receiving tubes sense the level changes caused by the infrared light emitted from the transparent groove on the character wheel to form a set of five digit numbers. After decoding, they are remotely transmitted to the system computer and displayed on the meter reading interface with the same number as the reading on the water meter window. The key technology of photoelectric direct reading sensors is absolute encoding, which recognizes the position of 10 digits from 0 to 9 on the character wheel by encoding the position of the character wheel digits; The second is to solve the problem of carrying and reading the high-order digits of two adjacent related character wheels "every 9 over 0"; The third is the perfect combination of mechanics and electronics, and the innovative structure of the water meter counter. The former is the foundation, while the latter is the key to the practicality of the product! The product has obtained relevant patents: ZL200810141680.3、ZL200820212544.4、ZL200820096062.7、ZL200820095833.0。

2、 Product features:

■ Structural innovation:The electronic part of the direct reading meter does not have mechanical contact with the counter movement device inside the meter, and does not affect the original measurement sensitivity.
■ Data Security:Pure digital signal encryption transmission adopts pure digital signal encryption transmission to ensure correct and secure data transmission.
■ Address code:Each table has a unique address code belonging to it, which facilitates management and maintenance.
