Wireless Lora Smart Meter DN15/20/25 Smart Water Meter Remote Meter Reading

Meter Summary:

This wireless remote water meter use LoRa modulation technology and through wireless to transmit and receive data, is a kind of wireless module with ultra-small, ultra-low power consumption, superior performance and ultra-long distance transmission.Module RF chip based on Speed Spectrum and Hopping Frequency technology, with features of high anti-interference and high reliability. So on the aspect of stability, anti-interference ability and also receiving sensitivity are all far beyond the existing GFSK modulation module. Which can solve the problems of balance the distance, interference with power consumption from traditional design project, to meet the requirments on long-distance transmission and high reliability.

Structure and Working Theory:

Inside the counter of water meter (mechanical part), there is one magnet embedded under the wheel pointer for 0.01 m3 of water and two reed switches beside each side of the wheel. Each time the pointer goes a circle, one group of two pulses is generated to represent 0.01 m3 of water being calculated. The pulses are converted to digital signals and recorded as metering data based on pre-set program. Then the metering data can be transmitted to a concentrator or hand-held unit.

Product Features:

Mainly applicable to new construction projects, or reconstruction projects for old residential area which are inconvenient for wiring deployment.
Wireless transmission technology is applied to realize out-door meter reading, which simplified system installation by avoiding wiring deployment.
The wireless transmission distance for hand-held unit is over 200 meters in open field.
Friendly user interface for management software of background platform. Variety of formats for data output and customized link with billing system according to customers'needs.
Total volume calculation of water flowing across the pipe and wireless meter reading.
Remote valve-control to solve arrearage problem.
Three-level automatic routing to increase transmission distance.
Real-time meter reading to realize ladder-type pricing.
Fully anti-water design, functional under the water.
ERFCU design, ultra-low power consumption.
WOR remote awaking technology to reduce power consumption.
Wamr Net routing protocol to ensure data security.
High speed transmission, data reading for single meter within 1.5 seconds.
Simple and practical structure with removable battery.
