Level gauge (magnetic float)
Side‑wall mounted instrument for corn steeping tanks, providing local real‑time level indication for sulfurous acid steep liquor. Optional high‑/low‑level alarm switches and 4‑20 mA remote transmitter feed signals to central‑control PLC, realizing interlocked control for feeding, circulation and discharging and preventing tank overflow or pump dry‑running. It replaces traditional glass‑tube level gauges and eliminates poor visibility from scaling plus glass‑breakage hazards, acting as standard instrumentation for corn steeping systems.
