Smart Ultrasonic Water Meter with NB-IoT & LoRa IC Card
IC card prepaid water meters
1- Built-in clock to control the valve to switch on and off regularly to prevent the valve from holding and scaling
2- Low-power design, built-in 3.6V lithium battery service life ≥6 years; Data be stored for more than 10 years after power failure
3- Top up meter credit before using water
4- Balance inquiry; Report the loss; Reissue a card; Record data and exception events
5- Warning of error, power shortage, water overlaying, water shortage, hoarding, etc.;
6- Available for single water pricing or Tiered water pricing.
Meters with single water pricing program is also available for water electrically and gas paid by one card.
Remote controlled water meters
1- The internal clock be calibrated by the upper computer.
2- Data be stored for more than 10 years after power failure
3- Battery voltage reported periodically
4- The meter reading period be set to report the meter data regularly.
After the benchmark water price and tiered water price based on the user category settled, the management software on the server settles the water charge according to the data reported by the water meter. Pre-paid / post-paid available.
- 5- Available for real-time/timing remote valve control.
- 6- Optional remote controlled meters.

- Frequency band: 800MHz～900 MHz.
- Low-power design, built-in 3.6V lithium battery service life ≥6 years
- Meter data be received and sent to the operator's cloud by the wireless transmission module through the NB-IOT channel.
The management software on server remote monitors the meters and settles the water bill based on the data extracted from the operator's cloud. |
- Frequency band: 470MHz～510 MHz
- Low-power design, built-in 3.6V lithium battery service life ≥6 years
- The concentrator communicates with the meters through Lora to receive data from meter, and sends data back to server by 4G/ Internet.
- Water meter parameters can be set and modified by the hand holder by operator. |
Mechanical characteristics & Parameters
1- Small initial flow, wide measuring range，High precision, stable performance
2- No moving parts inside，no choked flow parts, Not affected by impurities in the water, long service life.
