Overview
Product Model: LXSG-15~40 Product Introduction: The wireless remote water meter is an intelligent water meter developed by our company for remote meter reading and control. Our company uses magnetic water meters as the measurement basis, and through NB-IOT automatic networking for IoT, automatic remote meter reading of water meter usage is achieved, effectively avoiding the need for management departments to come to the door for meter reading. It has valve control function (optional), which facilitates management departments to control the water meter usage situation, making remote meter reading and control more convenient and reliable. While saving manpower, material resources, and financial resources, it effectively improves production efficiency.

Functional Features |
Remote reading：Proactively report readings periodically.
Operational level security：Two way authentication, strict encryption of the air interface.
Prepaid fees：Optional support for prepaid and pre order quantities.
early warning system：Alarm prompts such as battery undervoltage, abnormal metering, purchased quantity, and prepaid usage reaching threshold can be set according to different users for different emergency water usage.
Mass storage：Freeze data for 24 months.
Tiered water pricing：Water levels can be set with different benchmark levels and tiered prices based on user categories and usage.
| Performance characteristics |
Ultra long life battery: The standard ER26500 high-capacity battery ensures 6 years of use without the need for replacement.
Built in/external high gain antenna, stable and reliable signal, achieving full coverage without blind spots.
High sampling accuracy: Hall sampling has high reading accuracy.
The upload frequency can be flexibly set, and the data upload cycle can be set to meet the management needs of different users.
The protection level is IP68, which complies with the protection level specified in GB4208-2008 standard.
Patent for replaceable battery structure design, the battery box adopts an independent replaceable design, without the need to open the upper cover of the main body, making replacement convenient.
Gently press the touch area with your fingers for 3-5 seconds to activate the active data upload function, which can be used to immediately open the valve after successful payment.
