Applications & Suitability

Liquid Level Control: Accurate high and low point level monitoring in tanks containing water, oils, fuels, and chemicals.

Pump Dry Run Protection: Instant level detection in suction pipes and supply tanks to prevent costly pump damage.

Viscous & Sticky Media: Maintains accurate switching in syrups, paints, lubricants, glues, and wastewater.

Overfill Prevention: Safeguards storage tanks and mixing vessels against hazardous overflows.

Interface Detection: Detects boundary levels between immiscible liquids such as oil and water.

The RFLS-100L is a reliable, maintenance-free level measurement solution for industrial process automation.
