Description

The aesthetically made Level Controller by GIC India is perfect to protect submersible pumps from dry running and at the same time, prevents overfilling. It has a fully automatic operation functionality, helping it to drain and fill simultaneously.

  • Fully Automatic operation enabling both draining and filling simultaneously with a single device
  • Adjustable sensitivity level from 1k to 200k Ohm
  • Includes provision for Manual start
  • Protects submersible pumps against dry running and prevents overfilling
  • Enables maximum utilization of incoming liquid (eg. water) supply
  • Specially designed corrosion and shock resistant sensors to ensure trouble free operation.
