Hot Selling for Pin Type Polymer Insulator - LXSGY Wireless LORA water meter – HaimeiDetail:

The water meter uses modulation technology to transmit and receive data wirelessly. It is a wireless remote water meter with ultra-small size, ultra-low power consumption, strong performance, and long transmission distance. The radio frequency chip of the water meter module is based on spread-spectrum frequency hopping technology and has the characteristics of high anti-interference and high reliability; it has greatly surpassed existing modulation technologies such as GFSK in stability, anti-interference ability and receiving sensitivity. It solves the problem that traditional design solutions cannot take into account distance, anti-interference, and power consumption at the same time. It is the best choice for long-distance transmission and applications with high reliability requirements.

 

Product Features

1. Wireless wake-up: It can realize remote wireless wake-up and respond to the upper computer processing instructions in real time.

2. Sampling and measurement: A variety of sampling methods can be realized, such as pulse, photoelectric, etc., with high measurement accuracy.

3. Attack closing valve: It has the function of preventing external electric and magnetic attacks. When the sample is attacked by external electric or magnetic, the meter can automatically close the valve.

4. Remote control valve: With remote valve control function, it can realize pre-paid and post-paid functions.

5. In-position detection: With switch in-position detection function. When the normally open contact is closed in place, the meter switch valve is in place, and the valve operation can be stopped immediately.

6. Trigger upload: The module is always in sleep. You can trigger the module to upload real-time data once.

7. Low electric shut-off valve: When the battery voltage is lower than a certain value, the module can automatically close the valve and upload real-time data once.

8. Power-off and shut-off valve: When the water meter is powered off, the valve will be automatically closed to prevent accidental or artificial power-off; after re-powering on, the valve returns to the state before power-off.

9. Valve failure detection: Automatically determine whether the valve limit switch is working normally, and the valve can be opened and closed normally even if the limit switch fails.

 

Key technology

1. Intermittent pulse sampling technology: Converts periodic mechanical pulse signals into electrical signals for sampling and measurement, adopts the “double Hall counting” method, improves the installation structure and combines software filtering technology to ensure mechanical counters and electronic counts Full sync

2. LoRa spread spectrum communication technology: has the advantages of high anti-interference, high reliability, high sensitivity, long transmission distance, etc.

3. WOR electromagnetic wave wake-up technology: instantly wake up the water meter to make it in the communication state, and automatically return to the ultra-low power consumption state after the meter reading is finished.

4. PWM valve control technology: adopts pulse width modulation method, which effectively reduces the large current generated at the moment of valve action and prolongs the battery life;

5. TDMA time division multiple access technology: reasonable TDMA (time division multiple access) backoff algorithm, reducing the probability of data collision

6. Fully sealed design technology: using the latest nano-coating technology, no exposed electrodes, good sealing, and ensure the circuit board to work stably in a humid environment.

 

Product advantages

1. With anti-disassembly, anti-shear, anti-magnetic interference and other destruction methods

2. Simple installation, convenient maintenance, saving construction cost

3. Real-time monitoring of water meter status remotely, remote meter reading, remote control,

4. Compared with 3G and 4G cellular networks, LoRa technology applications and water meters are more scalable and cost-effective.
