Brass Class C Wireless Smart Residential Lora Water Meter

Hebei Shanghong Meters Technology Co., Ltd. is one of the leading manufacturers and suppliers of brass class c wireless smart residential lora water meter in China. If you're going to wholesale high quality brass class c wireless smart residential lora water meter, welcome to get pricelist and quotation from our factory.

LoRa wireless remote valve control water meter belong to high-tech products in the smart water meter, using of advanced wireless LoRa transmission technology, it transforms metered information of conventional mechanical water meter into electrical signal have it stored by micro-electronics control circuit. LoRa remote wireless reading dry dial household water meters is able to automatically read the metering data via wireless remote network and is also able to transfer the data to the back-office system (data center) after reading the meters. And it has the function of remote wireless control of the valve switch.Wireless Remote Ultrasonic Water Meter (LoRa) is an intelligent measuring instrument consisting of a flow sensor, a calculator and a wireless LoRa transmission module.

The calculator takes accurate measurements of the flow by processing the temperature difference collected by the sensor and the time difference between the sound waves passing through the fluid, and wirelessly transmits data through the LoRa module.

All parts of the flowmeter (including flow sensor parts and calculator parts) shall be installed in a position to avoid exposure, water injection, freezing, chemical and electromagnetic contamination and to facilitate disassembly and reading.

When the working time of the ultrasonic water meter is 6 years or less, but the data displayed on the display screen is not clear or indicating low power (please refer to the display instructions), the battery should be replaced by professional technicians to avoid affecting the normal operation of the water meter.

Technical parameter

Features of LoRa Water Meter

1. Point-to-point communication distance can reach 2KM.

2. Spread-spectrum modulation is adopted, which has a strong anti-interference ability to ensure effective and stable data transmission;

3. To achieve frequency division multiplexing, it is possible to copy several networks of the entire area with one frequency;

4. Adopt a non-magnetic transmission design to avoid magnetic adsorption and prolong the service life of mechanical parts;

5. The system is based on LoRa communication technology, adopting a simple star-shaped network structure, the communication delay is small, the transmission distance is long and reliable;

6. Synchronous communication time unit; FM technology avoids co-frequency interference to improve transmission reliability, adaptive transmission rate, and transmission distance algorithms, and effectively increase system capacity

7. No complicated construction wiring is required, the amount of work is small, the concentrator and the water meter form a star-shaped network, and the concentrator forms a network with GRPS / 4G and the back-end server. The network structure is stable and reliable.

Advantage

1. Real-time communication, active data transmission, water supply control

2. Because it belongs to short-distance communication technology, the transmission rate is relatively low, so the power consumption is small.

3. Since the frequency band of LoRa belongs to the free public frequency band, there is no long-term input cost.

4. Data docking can be realized, and the reading and control functions of our water meter can be sent to the customer's platform.

FAQ

1. How does the concentrator transfer data?

The concentrator needs a 220V power supply, and uses GPRS to wirelessly transmit data to the platform on the PC side;

2. Can I do a Lora ultrasonic valve control water meter?

No, because the built-in valve will have a greater impact on the stability of the ultrasonic measurement. The higher the frequency of the switch valve, the greater the impact on the accuracy of the measurement.
