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 mode :
(1)Component: Lorawan has four parts
Node: gas meter, water meter, position , alertor etc.
Gateway: receiving data
Network platform : Management of equipment in base station, DNSEG control etc.
User’s data background : data storage and application processing for user

The main chip of LORAWAN 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 Lorawan wireless spread spectrum chip .
(2)Product features:
1. measurement function

2. historical data store locally
* the data during latest 90 days store every one hour
* the data during the latest 180 days stores everyday
* the data during the latest 1 year stores every month
3. Power supply: one main battery for supplying daily , another one for spare battery
4. Main battery capacity level indicator
* In each measurement data consumption on the road up the service reported to the battery capacity level suffixü
* Low battery threshold :when the battery capacity is less than 20%, it will trigger low battery alarm and the low battery
alarming info.will be reported every 24 hours untill spare battery switch threshold
* Battery switch threshold : capacity of 10% will trigger the switch of spare battery
5. Spare battery switch only in the following cases; otherwise, use the main battery.
* Pull out the battery or the battery does not exist
* the main battery theshold is 10%
* The switch of spare battery is automatic so that i will not be outage
6. Spare battery function
* Water flow control partial measurement
* historical data storage
* spare battery exceeds 7 days at least
* When spare battery is used , the alarming info. Of spare battery will be reported to server
7. The spare battery protection in transportation
* Prior to on-site activation, the meter is equipped with only spare batteries, and in the warehouse or during transportation,
protection will be provided to prevent the consumption of the spare batteries.

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.
