The general purpose flow controller is offered in two configurations for low-flow pump and process protection. The LC80 accepts one flow sensor input and provides one 10A relay for low flow control. The LC82 accepts two flow sensor inputs and provides two 10A relays for dual low flow control. Package this flow controller with our liquid or gas flow switch sensors. For field mount installation, add a single or dual controller NEMA box.


  • Fail-safe relay control of pumps or valves with 0-60 second delay
  • Easy setup with LED indicators for sensor, power and relay status
  • 35 mm DIN rail mount PP enclosure with removable terminal strips
  • Invert switch changes relay state from NO to NC without rewiring
