01 / Overview

Electrode-Based Tank Level Control Without Mechanical Floats

The 61F-G3 AC100-220V is designed for stable level regulation in water and conductive-liquid applications where mechanical float devices are prone to wear or contamination. Using electrode inputs, it provides practical control for filling and draining operations in utility and process-support systems. This controller is widely used in panel-based pump automation, offering a proven approach for maintaining liquid levels with reduced moving parts and straightforward maintenance procedures.

Typical Applications

  • Controlling make-up water tank filling pumps
  • Monitoring sump level in plant utility rooms
  • Automating reservoir refill cycles in production facilities
  • Managing cooling-water service tank level
  • Providing high/low level supervision in auxiliary process tanks
  • Replacing mechanical float methods in retrofit projects

Buying Checklist

  • Electrode method improves durability versus mechanical floats

Frequently Asked Questions

What liquids can this controller detect?

Conductive liquids only: water, wastewater, chemicals with conductivity >100μS/cm. Cannot detect non-conductive liquids: oils, solvents, distilled water, deionized water.

How does floatless level control work?

Three electrodes detect liquid level: common (always submerged), low level, high level. When liquid bridges electrodes, control circuit activates relay. No moving parts, no mechanical wear.

What electrodes do I need?

61F series electrodes (sold separately). Choose based on tank depth, liquid type, mounting method. Common configurations: rod electrodes for tanks, cable electrodes for deep wells.

Can this controller pump in and out?

Yes, configurable for fill control (pump in when low) or drain control (pump out when high). Set via wiring configuration. Some models support both modes.
