With the advancement of smart city construction, smart water meters are gradually replacing traditional water meters and becoming important terminals for household and industrial metering systems. It can not only achieve remote meter reading and real-time monitoring, but also realize data management and intelligent warning functions, greatly improving the efficiency and intelligence level of the water supply system.
However, in complex environments such as long-term outdoor, high humidity, high temperature, and rain, the reliability of smart water meters faces enormous challenges. One of the easily overlooked core hazards – poor sealing of the lead out hole – is becoming one of the main causes of water meter failure, leakage, or communication abnormalities.
1、 Why is “sealing the lead out hole” so crucial?
Smart water meters typically integrate highly sensitive components such as electronic motherboards, sensing modules, and communication modules. Once water vapor or dust enters through the outlet holes, it may cause:
Circuit short circuit or corrosion, resulting in module damage;
Abnormal data collection, affecting remote communication;
Reduced protection level and significantly shortened lifespan;
The repair rate of enterprises has increased, leading to an increase in after-sales costs.
🔧 Traditional methods such as sealant, heat shrink tubing, and foam sealing often cannot simultaneously achieve sealing, flexibility, and aging resistance. Therefore, there is an urgent need for a more reliable and professional sealing material to provide long-term effective sealing protection for smart water meters.

Actual application scenarios
SIPC 1823 is not only suitable for sealing the outlet holes of smart water meters, but also widely used in the following typical application scenarios:
🧩 Adhesive sealing of electric meter/water meter housing
🔌 Sealing and protection of sensor cable outlet
🔧 PCB board components/wiring harness fixation
🛡 Optoelectronic display, small module sealing and plugging
🔋 Adhesive bonding and protective film sealing of lithium battery shell
For intelligent water meter systems that operate outdoors for a long time, every sealing point is related to the stability and safety of the equipment. Although the lead out hole is small, it may become the “lifeline” of the system.
