Wireless ultrasonic water meter (LoRa )is an intelligent measuring instrument with a flow sensor and calculators. The calculator used the sensor and through the water of time difference to collect temperature differences and sound waves to complete accurate measurement of water flow. It can transmit data through a wireless LoRa module. And can provide important applications and data for many applications in the pipeline. It has a higher measurement accuracy and is not subject to sand and wear and has a longer service life.
LoRa intelligent ultrasonic water meter: It adopts advanced wireless transmission technology to realize remote centralized reading of remote water meter, concentrator and computer, without wiring, simple and convenient construction, and effectively solves the problem of difficult meter reading. The remote water meter uses the wireless network of the meter, the signal is covered without gaps, there is no blind spot for meter reading, the valve is designed with anti-rust function, and the valve can be automatically opened and closed. Frequency automatic calibration technology: Automatically adjust operating parameters, effectively avoid frequency offset caused by environmental changes, and achieve ultra-high meter reading rate.
Lora Ultrasonic Water Meter Wireless Transmission
1) Power: Lora: (2.1-3.6)V
2) Working frequency: Lora: (488～510/865~868)MHz;
3)Transmit power: Lora: 50mW;
4)Average current: Lora: 18uA;
5)Transmission distance: Lora: 1km;
6)Instructions for use: It uses a free public wireless frequency band, and the Lora concentrator is required. (The repeater is optional depending on the on-site environment);
Note：
★The Lora frequency can be customized according to actual requirements
★The frequency of uploading data is not more than once a day, otherwise, it will affect the service life of the battery;
★If the water meter is immersed in water, it will greatly weaken the ability of wireless transmission;
★The management party needs to regularly record and verify the readings of the body part of the water meter.
