Description

Technical Field

[0001] The utility model relates to the technical field of non-magnetic water meters, in particular to an NB-loT Internet of Things non-magnetic water meter. Background Art

[0002] A water meter is a device used to measure and record the volume of liquid (usually water) flowing through a pipeline. Water meters are usually installed on water supply pipelines. By measuring the volume of the liquid flowing through the water meter, the water consumption of users can be determined, which helps to achieve accurate measurement and management of water consumption. A non-magnetic water meter is a water meter specially designed to measure the flow of non-magnetic media. Its working principle is to calculate the flow rate by detecting the magnetic field change generated when water flows through the water meter. Compared with traditional magnetic water meters, non-magnetic water meters have higher accuracy and stability, and are especially suitable for environments sensitive to magnetic field interference, such as hospitals, chemical enterprises, etc.

[0003] An NB-IoT Internet of Things non-magnetic water meter refers to a water meter that uses narrowband Internet of Things technology and incorporates the characteristic of being able to work normally without external magnetic field interference in its design. This kind of water meter combines NB-IoT communication technology and can realize functions such as remote monitoring, remote meter reading, and data transmission through Internet of Things technology. At the same time, it is not affected by external magnetic fields, ensuring the accuracy and stability of water meter measurement.

[0004] Existing NB-IoT Internet of Things non-magnetic water meters have certain drawbacks when in use. When existing NB-IoT Internet of Things non-magnetic water meters are in use, the control box installed on the non-magnetic water meter is usually assembled by a box body and a box cover, which is convenient for people to disassemble and maintain. However, there are gaps between the box body and the box cover, and when affected by temperature differences or other environmental factors, it is easy to cause fogging and water ingress, resulting in potential safety hazards. Therefore, it cannot meet people's needs. Summary of the Utility Model
