LoRa wireless hot water meter (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 the lower limit temperature of the medium beingA water meter with a maximum temperature of 30 ℃ and a temperature limit of 0 ℃. 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.

Wireless remote meter reading usageThe implementation of "Internet of Things networking counting technology" adopts the national licensed 470MHz dedicated meter reading frequency, which can automatically and manually network, achieving an optimal balance between reliable communication and low power consumption. The intelligent remote water meter module adopts the current ultra-low power MCU, RF chip, and LORA spread spectrum frequency hopping technology, which greatly improves its transmission efficiency on the basis of low energy consumption. The transmission distance in open space can reach 2-5km (low power consumption, stable performance, long transmission distance).

major function

（1）Remote water meters utilize advanced wireless transmission technology to achieve remote meter reading with collectors, concentrators, and computers, without the need for wiring. The construction is simple and convenient, effectively solving the problem of difficult meter reading.

（2）The remote water meter is corrosion-resistant, does not scale, has a long service life, and can avoid pipeline scaling, blockage, and yellow rust. Long term use of tap water does not affect the water quality inside the meter.

（3）The remote water meter utilizes wireless networking of meters, with seamless signal coverage and no blind spots for meter reading.

（4）The remote water meter has a beautiful appearance, reasonable size, smooth inner wall, and low pressure loss.

（5）There are two types of remote water meters: ordinary and water-saving, which can be selected according to user needs.

Product Highlights

（1）Remote meter reading: Through the system, remote wireless meter reading and scheduled meter reading can be achieved.
