NB Smart Water Meter

Introduction:

NB smart water meter communicates remotely with servers through Narrowband Internet of Things (NB IoT). No need to use collectors or concentrator devices, using a point-to-point connection method with a single meter flow card,. The equipment installation work has been simplified, and automatic remote meter reading of water meter usage has been achieved, effectively avoiding the manual work of on-site meter reading by management departments. This water meter has valve control function, which can facilitate the management department to control the water usage of the water meter, making remote meter reading and control convenient and reliable. While saving manpower, material resources and financial resources, it effectively improves production efficiency.

NB Intelligent Water Meter Technical Parameters:

1、 Built in data card: using telecom industrial grade SIM card (patch type), resistant to high and low temperatures (-40 ° C -+105 ° C);

2、 Data usage duration: NB data cards can customize data usage duration according to customer needs, without worrying about unpaid fees or network disconnection;

3、 Remote reading: Proactively report readings on a periodic basis;

4、 Remote valve control: capable of remotely closing and opening valves;

5、 Prepaid: Supports prepaid and pre order quantities, and closes the valve for overdue payments;

6、 Warning system: Alarm prompts such as battery undervoltage, abnormal measurement, pre order quantity, and prepaid usage reaching threshold;

7、 Built in antenna: Built in antenna, stable and reliable signal, achieving full coverage without blind spots;

8、 Built in battery: Built in lithium battery with a capacity of over 6 years.

NB Smart Water Meter Function Introduction:

1、 Anti theft water function: When there is strong magnetic interference with the measurement signal, the water meter automatically closes the valve until the strong magnetic disappears, preventing the use of strong magnetic to steal water.

2、 Undervoltage warning function; When the built-in battery voltage is insufficient, the system will automatically report a prompt for timely battery replacement.

3、 Rust prevention function: Using automatic on-off valves twice a month to prevent rusting caused by prolonged valve inactivity and improve operational stability.

5、 Using NB-IOT wireless communication technology, the signal coverage range is wide, which can ensure the normal transmission of data.

6、 Equipped with a battery compartment for easy battery replacement, facilitating on-site battery replacement.

7、 Protection level: IP6/8 level
