Photoelectric direct reading hot water meter (M-Bus, ductile iron)

product overview

The hot water meter and the cold water meter only use different materials internally. A hot water meter can run cold water, but a cold water meter cannot run hot water. Cold water meter used for cold water: refers to a water meter with a lower limit temperature of 0 ℃ and an upper limit temperature of 30 ℃ for the medium. Hot water meter used for hot water: refers to a water meter with a lower limit temperature of 30 ℃ and an upper limit temperature of 90 ℃, 130 ℃, or 180 ℃ for the medium. Under normal atmospheric pressure, the upper limit of a hot water meter is 90 ℃, which is mostly used for ordinary household water meters.

The photoelectric direct reading remote transmission water meter is a self-developed direct reading remote transmission water meter that is convenient for remote meter reading and control, designed to meet the practical needs of daily water use. It adopts M-BUS/RS485 bus communication to achieve remote direct reading of water meter usage, effectively avoiding the need for management departments to come to the door for meter reading. This product also has valve control function (optional), which facilitates the management department to control the water usage of direct reading remote water meters, making remote meter reading and control more convenient and reliable. While saving manpower, material resources, and financial resources, it effectively improves productivity.

major function
