1、 Product Overview:

The IoT valve controlled cold (hot) water meter adopts advanced narrowband cellular communication technology. A separate control box is installed outside the water meter, and a low-power industrial grade highly integrated NB IoT communication module and industrial grade IoT SIM card are built-in. The signal network has deep coverage (underground meter wells, pipeline wells, etc. can all be used normally).

2、 Product composition:

The entire system of the water meter consists of NB IoT management system platform, base station, and water meter.

The microcomputer in this water meter automatically measures and stores water usage, and can automatically detect information such as the battery status of the water meter and the sampling sensor of the instrument. It has a long communication distance and efficient error correction coding technology, which greatly improves its resistance to sudden interference and sensitivity. It also has reliable error detection capability and can automatically filter out errors and false information. With many advantages such as ultra-low power consumption, wide connectivity, stable and reliable communication, simple construction, cost savings, easy operation, and convenient maintenance, it truly realizes the Internet of Things.

3、 Product Features

ØAutomatic reporting:Proactively upload data at regular intervals;

ØTrigger upload:The water meter is usually in sleep mode and can be triggered to upload real-time data once;

ØIP68 Waterproof:Fully sealed design, all circuits are sealed with high-performance sealant, without any exposed circuits. The battery product uses waterproof batteries, and the actuator adopts copper sealed red stamping manufacturing process. The overall waterproof rating of the product reaches IP68;

ØUnique address:The table has a unique address identifier, ensuring the uniqueness and correctness of the data;

ØSplit structure:The product adopts a split structure, which can lead the electronic part to the wellhead when installed in a deep well. The electronic part has a better working environment, more reliable operation, and more stable signal;

ØStability and reliability:Adopting microcomputer and micro memory technology, highly integrated and reliable;

ØSpecial mechanism design:Discrete reporting mechanism: Discretize according to the last four digits of the IMEI number on the module used by the table side module. The discrete reporting interval is from 0:00 to 6:00, and the estimated reporting time is 30 seconds; Valve washing mechanism: The meter end module automatically performs valve washing every 30 days, with a half open and half closed operation during valve washing. If the module was originally in the open valve state, after reaching the valve cleaning date, the module will first close the valve halfway and then fully open the valve. If the module was originally in a closed state, after reaching the specified date, the module will first open the valve halfway and then completely close the valve.

ØControl valve:Attack valve closure: With anti magnetic attack function, when the sampling is subjected to external magnetic attack, the meter can automatically close the valve; Remote control valve: With remote valve control function, preset switch valve commands can be achieved through finger touch; Valve fault detection: Automatically determine whether the valve limit switch is working properly, and even if the limit switch fails, the valve can still be opened and closed normally.

4、 Product Features:

Storage function:Store once per hour, store accumulated water volume, 24 pieces of data per day, up to 30 days of storage

Regularly report dataWhen the set upload time is reached, the water meter will automatically upload data. To avoid data congestion, a discrete mechanism is adopted for uploading

Proactively report faultsProactively report magnetic attacks, valve abnormalities, and low power situations

Touch the button to trigger active data upload: The water meter can be manually touched to force it to go online and upload data

Remote control valve functionThe platform can issue instructions to enable the meter side module to perform valve opening and closing operations

set upIPAnd portsThe platform can issue instructions and change the module upload IP and port

Set reporting cycleThe platform can issue instructions to set the reporting cycle of the table side module, which can only be set to

1~24h

Remote UpgradeBy issuing instructions, the module can receive the upgrade package and perform program upgrade operations

Query reporting cycleYou can issue a query reporting cycle instruction through NB, and the table side module will reply with the current reporting cycle after receiving the query frame.

Query historical dataYou can issue a query historical data command through NB, and after receiving the query frame, the table side module can reply with frozen data on the specified date within the past 30 days
