Key Features
Real‑time level display – Bright digital or dual‑display (digital + bar graph) readout shows current liquid level or volume at a glance.
Flexible input compatibility – Accepts standard 4‑20mA signals from virtually any compatible level transmitter, pressure sensor, or float switch.
Adjustable setpoint control – Upper and lower alarm/control points can be programmed on‑site via front‑panel buttons. No special software or computer required.
Relay outputs for pump/valve control – Built‑in relay contacts (typically 5A or higher) directly control pumps, solenoid valves, fans, or alarm buzzers.
Manual/Auto operation – Switch between fully automatic control and manual override for maintenance or emergency situations.
Optional communication – RS‑485 (Modbus) or 4‑20mA retransmission available for integration with SCADA or building management systems.
Rugged enclosure – Sturdy metal or polycarbonate housing suitable for industrial environments, with optional weatherproof or explosion‑proof versions.
