Mechanical structure and characteristics:

1. Low starting flow rate, wide range ratio, high measurement accuracy, stable operation;

2. There are no moving parts or flow blocking components inside, which are not affected by impurities in water and have a long service life.

Electronic features:

1-The clock in the table can be calibrated by the upper computer;

2- Data can be saved for more than 10 years after power failure;

3-Regularly report battery voltage;

4-The reading cycle can be set and the water meter readings can be reported regularly;

The server-side management software sets benchmark water prices and tiered water prices based on user categories, and settles water fees according to the data reported by the water meter;

The software supports prepaid/postpaid.

*NB-I0T

-Frequency band: 800MHz~900 MHz;

-Low power design, built-in 3.6V lithium battery, with a service life of ≥ 6 years;

-The wireless data transmission module of the water meter communicates with the operator's cloud through the NB-10T channel to send and receive water meter data. The server-side management software extracts water meter data from the operator's cloud, monitors water meters, and settles water bills.

*Lora

-Frequency band: 470MHz~510 MHz;

-Low power design, built-in 3.6V lithium battery, with a service life of ≥ 6 years;

-The wireless data transmission module of the water meter communicates with the concentrator through Lora wireless communication. The water meter data is read back by the concentrator and transmitted back to the server via 4G/Ethernet.

-The water meter parameters can be set and modified by the handheld device.

*M-bus

-Communication speed: 1200bps/2400bps/4800bps.

-The water meter communicates with the concentrator through the M-BUS/RS485 bus, and the water meter data is read back by the concentrator and transmitted back to the server via 4G/Ethernet.

-The working voltage of the water meter is powered by the bus at DC24V; Built in backup power supply DC3.6V, static current<25 μ A.
