LoRa wireless remote pulse water meter is a kind of remote water meter
which is convenient for remote meter reading and control, which is developed by China Water for the actual need of intelligent management of water supply company. The table is a smart water meter with remote meter reading based on the traditional mechanical dry water meter, adding electromechanical conversion components, data storage components, and NB-IoT communication components. The impeller in the water meter rotates with the impact of the water flow, driving the movement of the magnetic pointer, the reed tube and the magnetic pointer work together to form a pulse group of equal proportions, and the processor in the smart water meter records the number of pulses, and the water meter reading can be accumulated. Through the micro-power application metering frequency band (470~510MHz) and collector concentrator communication, data uploaded to the concentrator, by the concentrator unified through the GPRS module and the master station communication data uploaded to the master station, to achieve the automatic remote transmission of water meter use, support two-way communication, can be real-time switching valve, real-time point copy, The meter is normally in low power mode. After the concentrator sends the meter reading command, the water meter at the specified address wakes up to read the meter, and then continues to enter low power, effectively reducing the meter power consumption. This product also has the valve control function (optional), which is convenient for the management department to control the water consumption of the water meter,making the remote meter reading and control more convenient and reliable, saving manpower, material and financial resources at the same time, effectively improve the production efficiency.
² Power supply battery: mainly used to store batteries for disassembly.
² Case: It is mainly used to install the metering and acquisition module, circuit board and valve-controlled motor in it.
² Base table: mainly used to measure the current water consumption.
² LoRa communication module, supporting custom protocols.
² Through hole ball valve (optional) : mainly under the control of the main circuit board, the tap water flowing through the table is closed and opened.
Technical characteristics
² Remote reading: Periodic timing of the active on the report meter reading.
² Remote valve control: remote valve close and open (optional).
² Support built-in/external antenna, signal stability and reliability, achieve full coverage, no blind area.
Flexible setting of upload frequency: data upload cycle can be set to meet the management needs of different users.
² The electronic reading device does not affect the measurement accuracy of the original primary instrument.
² Power supply battery independent, easy to disassemble and replace.
² Using wireless LoRa data transmission technology, the autonomous network is easy to maintain, and the signal is stable and reliable.
² Large capacity data storage, recording equipment operation information and 3 years 1095 days of daily frozen data, including the daily maximum instantaneous flow, minimum instantaneous flow and alarm information, can provide a basis for disputes arising in the use of water meters.
