  • Smart water level sensor | with LoRaWAN / 4G / WiFi | 0–10 m (up to 500 m) | IP68 | 4–20 mA / RS485 | stainless steel

    Code: ES-PL301

    Water (liquid) level sensor designed for accurate and reliable monitoring of levels in tanks, reservoirs, wells, or open water systems. The device supports various communication protocols – LoRaWAN, 4G, WiFi, Zigbee, making it easy to integrate into modern IoT (Internet of Things) systems. Thanks to high accuracy, IP68 sealing, stainless steel housing, and a wide measurement range, this sensor is suitable for both household and industrial use. It is a solution that enables real-time monitoring of liquid levels and optimization of resource management.
