LEDAER Communicating Type
Heavy-Duty Long-Range Magnetic Level Gauge for Large-Scale Storage Tanks
📌 Brief Introduction
The LEDAER Communicating Type is a heavy-duty, long-range magnetic level gauge specifically engineered for large-scale storage tanks. As an advanced evolution of the traditional float-plate design, it utilizes a sophisticated force-balance system to provide highly accurate and stable level monitoring for heights up to 20 meters. It is the ideal choice for massive reservoirs and industrial tanks where side-mounted gauges are impractical.
How It Works – Force-Balance System
The system operates on the principle of buoyancy and force equilibrium. A high-buoyancy float is connected via a durable stainless steel wire or sling to a magnetic weight system. As the liquid level changes, the float moves accordingly, driving the magnetic weight within a vertical guide tube. This movement is captured by the external magnetic indicator, providing a clear, continuous visual reading. Its robust mechanical structure makes it incredibly reliable for outdoor and high-altitude tank monitoring.
✔️ Friction-reduced pulley movement
Designed for Massive Tanks
Overcomes the height limitations of standard magnetic gauges. Achieves reliable measurement up to 20 meters with ±10mm accuracy. Ideal for crude oil terminals, deep water reservoirs, and tall chemical silos where side-mounted installation is impossible.
✔️ Weather-proof & remote-ready
