This series of Wireless Digital Liquid Level Gauges is a high-precision, low-power industrial metering instrument powered by a long-lasting 3.6V lithium battery. Built with an explosion-proof aluminum alloy housing and a 304 stainless steel submersible probe with IP68 protection, it measures real-time fluid levels with exceptional long-term stability. Featuring an integrated MCU and full-screen LCD display, the meter transmits data to cloud platforms seamlessly via 4G, NB-IoT, or LoRa cellular networks.

Key Features & Highlights

• Multiple Transmission Options & Flexible Configuration: Supports 4G, NB-IoT, and LoRa networks with programmable IP address settings. Parameters such as sampling/upload rates and alarm thresholds can be easily configured remotely or via on-site Bluetooth connectivity.

• Rugged Construction & High Precision: Features an explosion-proof alloy aluminum casing, 304 stainless steel connector, and IP68 submersible probe. Delivers high accuracy (0.5% FS) with built-in high-precision pressure sensors and anti-electromagnetic interference protection.

• Real-time Monitoring & Intelligent Alarms: Equipped with high/low level limit threshold alarms, low-battery alerts, and GPS positioning functionality to keep assets secure and monitored.

• Ultra-Low Power Consumption: Operates on a high-capacity 3.6V lithium battery (optional 12V/24V external supply) with customizable sampling (1–9999s) and uploading intervals (10–9999 mins) to maximize field operational lifespan.

• Full-Screen Display & Broad Application: Designed with a 76mm full-screen LCD for clear local data reading. Suitable for non-corrosive liquids including water and oil across pipelines, reservoirs, and industrial storage tanks.
