Measurement introduction
Reed tube is a kind of passive electronic part, which is widely used in various communication equipments. It is a kind of circuit switching device controlled by magnetic field signal, also called "magnetron".The tube is fitted with two iron spring plates and is filled with an inert gas called the metal rhodium.Normally, the two reeds are separated. When a magnetic material approaches, under the action of magnetic field lines of force, the two reeds in the tube are magnetized and attracted to each other, connecting the circuit connected by the two pins.

Metrological characteristics
(1)Compact structure and small weight.
(2)The switch components of the reed switch are sealed in the inert gas, which will not contact with the external environment, and the working life is long.
(3)No sliding element is used to prevent metal fatigue and ensure unlimited mechanical life.
product brief introduction:
Reed tube water meter: magnetic sensitive switch, used as a sensor, long life, in the traditional mechanical water meter with reed tube and magnet. When the magnet is close to the reed tube, the reed tube is closed, and when the magnet leaves, the reed tube is open. The calculated pulse signal is output from the surface. The accuracy of measurement is related to the accuracy of the pulse quantity.
product superiority:
1、 The case is lead-free copper, no toxicity, no pollution, anti - aging.
2、 Adopt multi - flow beam movement, small initial flow, high measurement accuracy.
3、Integrated module, low power consumption design, metering process is completed in the meter.
4、 The valve is maintained regularly to ensure that the valve works normally.
5、 Battery power, moisture-proof, anti-static, effectively ensure the service life of the meter.
6、The meter is mainly measured by means of dry spring tube, and the charging method is settled by means of system settlement. If there is no water, it may be overdue.
7、 The main function of this watch is valve control: after reaching the operator's platform under the instruction of valve, the meter can only receive the instruction from the platform when it needs to report the data of the meter, and then execute the switch valve.

Communication introduction
The main chip of NB-IOT communication module adopts the high-performance embedded ARM cortex-m3 32-bit RISC controller, which
ensures the stability of the device with multilevel software detection and multiple hardware protection mechanisms.It is composed
of the powerful ARM cortex-m3 32-bit RISC microcontroller and NB-IOT wireless spread spectrum chip .

Product features are as follows:
(1) nb-iot module adopts LGA package, small in size, compact in structure and easy for embedded product application;
(2)wide voltage supply design, suitable for more applications;
(3) integrated TCP/UDP and other data transmission protocols and embedded rich network service protocols, easy to design and
upgrade products;
(4)passed the high and low temperature test, in line with the industrial environment;
(5)provide upper computer software to realize on-site test equipment and compatibility with existing equipment;
(6) deep coverage: 100 times more coverage than GSM;
(7) mass connection: each community can provide 50,000-100,000 connections;
Low power consumption: the useful life of terminal battery is over 6 years;

After the communication module is superimposed, if combined with the integrated energy
control platform software independently developed by the company,It can realize:
* Unmanned, reduced manpower.
●automatic data logging.
●Industrial-grade communication equipment ensures the safety and reliability of meter reading.
●Complete system log traceability is available.
●Visual graphics, data statistics.
●Meter status alarm;When low-power and low-volume magnetic attack sampling fault leakage alarm (external leakage alarm) occurs,
real-time alarm information is uploaded to the background application platform.
●Control the gasmeter valve switch through background application software (desktop WEB and mobile APP).
●When the meteris removed or attacked by external forces, the information will be transmitted to the background application
platform in real time
●The stability of data transmission can be monitored.
