Custom Anti-interference & Moisture-proof Induction Coil for Smart Water Meters

IoT smart water meters are core terminal equipment of smart water service systems, relying on precision induction coils to complete water flow pulse collection, accurate metering and remote data transmission. Installed in humid and electromagnetically complex pipe wells and underground equipment rooms, smart meters require supporting coils with excellent anti-interference, moisture-proof and anti-oxidation performance. Ordinary coils are prone to signal drift, pulse missing and metering errors in harsh environments, causing data disorder and measurement disputes between water service enterprises and users.

Our client is a high-tech enterprise specializing in the R&D and production of IoT smart water meters, supporting national municipal smart water renovation projects with products compliant with national metering standards. The original coils had unstable pulse collection and metering drift in humid and strong interference environments, failing project acceptance inspection. The client needed moisture-proof, anti-interference induction coils with zero parameter drift and accurate pulse collection to meet national water metering specifications.

Fuying Electronics adopts moisture-proof and anti-oxidation enameled wire and double-layer insulating sealing technology to prevent damp aging and insulation failure. The optimized shielding winding structure filters external electromagnetic clutter and stabilizes pulse signals, fundamentally solving metering deviation and data fluctuation problems. Precise winding parameter calibration ensures accurate and complete water flow pulse collection. All coils pass simulated harsh environment aging tests to guarantee long-term operational stability and batch consistency.

After large-scale application in municipal smart water projects, the client’s smart water meters achieve 100% inspection qualification rate with accurate metering and stable data transmission in long-term humid and complex electromagnetic environments, fully passing national metering certification. The equipment maintenance rate is significantly reduced, realizing intelligent and efficient water metering management. Fuying Electronics provides high-precision, anti-interference and moisture-proof customized coils for smart water meters, gas meters and flow monitoring terminals.
