AD-15/ADI-15/ADT-15 Flow Switch

A range of simple in line flow switches to detect the flow of gases and liquids. The switches are suitable for many applications including-

  • Refrigeration of machine-processes
  • Hydraulic and lubrication circuits
  • Thermal oil circuits
  • Gas circulation control
  • Series AD-15 is equipped with one or two reed detectors.
  • Series ADI-15 is equipped with reed detectors and local indication of the flow.
  • Series ADT-15 is equipped with reed detectors, local indication of the flow and a 4-20 mA transmitter.
