Shancheng RS485 Photoelectric Remotely Reading Gas Meters use very advanced micro-electronics technology. It owns lots of features, such as high integrated level, high measure accuracy, low power consumption, numbered rollers display, convenient installing etc. This technology is very good for domestic gas meter and industrial gas meters.
Working principal
This meter, through transmission type optical-to-electrical transducing, reads value of the numbered rollers in mechanical meters immediately. With photoelectric encoder technology, we treat each numbered rollers as a code wheel, the five infrared receiver tubes receive the infrared light sent from the numbered rollers and causes electrical level fluctuation to form a group of 5 digits code. After decoding, these codes will be sent to the computer and displays the same number in the numbered rollers of mechanical meter.
