GIC & HIQUEL Liquid Level Relays

GIC and HIQUEL Liquid Level Relays are designed for conductive liquid level detection and control in tanks, sumps, and reservoirs. Using stainless steel or conductive probes, these relays detect fluid presence or absence to automatically control pumps, valves, and alarms in water and process systems. They provide reliable operation even in harsh industrial environments.

🔧 Technical Highlights:

• Function: Monitors conductive liquids to control filling or drainage via electrode probes.
• Operating Principle: Conductivity-based sensing using low-voltage AC signals to prevent electrode corrosion.
• Control Modes: Configurable for fill or drain operation with automatic or manual reset options.
• Supply Voltage: Universal 24–240 V AC/DC (model dependent).
• Sensitivity: Adjustable range from 5 kΩ to 100 kΩ for various liquid conductivities.
• Outputs: SPCO or DPCO relay contacts for pump or alarm control circuits.
• Mounting: DIN rail 35 mm housing; panel mount versions available.
• Indicators: LED status display for power, probe condition, and output status.
• Compliance: CE and RoHS; designed to IEC/EN 60255 standards for control and protection devices.

✅ Benefits:

• Automatic level control for tanks, sumps, and reservoirs.
• Protects pumps from dry-running and prevents tank overflow.
• Adjustable sensitivity for clean or contaminated liquids.
• Compact, maintenance-free design with universal voltage operation.
• Proven reliability from GIC and HIQUEL in industrial and process control systems.

🚀 Applications:

• Water and wastewater treatment plants.
• Pump control panels and borewell systems.
• Chemical process and liquid storage tanks.
• Cooling towers, HVAC systems, and condensate pumps.
• Industrial machinery requiring liquid level monitoring or interlocking.

GIC and HIQUEL liquid level relays offer dependable, adjustable, and safe liquid level control, ensuring efficient pump automation and protection for industrial and commercial fluid systems.

FAQs

• Q: How does a liquid level relay work?
  A: It uses electrode probes immersed in a conductive liquid. When the liquid makes contact, the relay detects the change in resistance and switches the output to control pumps or alarms.
• Q: Can these relays be used with non-conductive liquids?
  A: No. Conductive level relays work only with liquids that can conduct electricity (e.g., water, wastewater, or chemical solutions). For non-conductive fluids like oil, use a capacitive or ultrasonic level controller instead.
