Product Description
Intelligent IoT Smart Water Meter LXSY-TW Type Digital Water Flow Meter
- Product Overview
LoRaWAN IoT water meter is composed of water meter base meter, electric ball valve (valve control), magnetoresistive sensor,
MCU, wireless communication module, control circuit and other components. Mechanical and electrical separation structure design.
High capacity lithium sub battery pack is used for power supply. It provides long-term stable energy guarantee for data acquisition,
valve control and wireless data transmission. LoRaWAN wireless communication module is adopted. Through the spread spectrum communication technology, the user water data is actively uploaded (once a day by default) to the LoRa WAN gateway. The gateway
will upload to the system data service center through LTE 4G network or Ethernet. The system has the advantages of long communication distance, large capacity, fast and convenient installation, long service life, etc.
This water meter is of dry structure. The dry water meter is isolated from the measured water due to its counting mechanism. Therefore,
it is not affected by the suspended impurities in the water to ensure the normal operation of the counting mechanism and the clear reading.
At the same time, it will not, like the wet water meter, affect the reading of the water meter due to the fog or condensation under the glass
caused by the temperature difference between inside and outside the meter.
- Functions and features
1. Split structure: The electronic unit is independent from the base table.
2. Accurate measurement: non-contact full-electronic detection logic is adopted. The metering accuracy is 10 liters.
3. It has the functions of touching the key to wake it up and long press key to go online and transmit data remotely.
4. It has infrared communication interface. Relevant parameters can be read and set.
5. It has alarm functions: Abnormal state battery voltage and valve, continuous small and large flow, metering module failure,etc.
6. Timed collection and upload function:Collect data timed. Auto upload data at the set time point (once a day by default). Meanwhile,
it can receive and execute instructions from the platform.
7. Auto switching of reporting mode: When the on-site signal is abnormal, it will auto switch to monthly mode. While it's recovered,
it will auto resume the daily mode.
8. LP design: 3.6V lithium sub-battery pack (ER26500+HPC1520) is adopted. Sleep current is less than 10uA.
