ANLY A61F-GP-N Water Level Controller

ANLY A61F-GP-N Floatless Water Level Controller is a compact, AC-powered device that automatically regulates the liquid level in tanks containing conductive liquids by switching an output when the level reaches predefined points. It is designed for conductive liquids and should not be used with volatile liquids. The controller implements a three-threshold level scheme (E1, E2, E3) to define high, medium, and low levels and includes surge protection to guard against transient disturbances; the electrode heads operate at low AC voltage to minimize electrolysis and extend their service life. Two indicator LEDs show water-supply and drainage status, providing at-a-glance operation feedback. The A61F-GP-N is part of ANLY’s A61F-G family of floatless relays, and manufacturer literature provides wiring diagrams that connect to a power source and earth and notes compatibility with common AC mains voltages (110/220 VAC) with configuration details. This controller is suitable for automatic water-supply control in tanks, reservoirs, and similar vessels where a conductive liquid is used, offering reliable, mains-powered level control without a float switch.
