ROTARY TYPE PHOTOELECTRIC DIRECT READING WATER METER
Classification:
Keyword: Water Meters
Detailed
DESCRIPTION
The rotary type photoelectric direct reading water meter adopts a rotary type metering structure, which measures water consumption by driving the impeller to rotate through water flow. It integrates photoelectric sensors internally. When the character wheel rotates, the light signal will shine on the photoelectric sensor through the light hole on the character wheel, thereby generating electrical signals. These electrical signals are processed, converted into digital signals, and transmitted wireless or wired to the upper computer or data acquisition system to achieve remote meter reading and data management. It has the characteristics of high-precision metering, remote meter reading, and low-power design.
