Features

  • Adjustable

  • Confirms: Normal flow conditions

  • Senses: high flow or low flow conditions

  • Output: Switch Contact
Operation

When flow is increased, the magnetic piston is forced against a bias spring. As the magnet comes near the adjustable read switch it actuates, indicating proper flow. When flow decreases the spring forces the piston in the opposite direction deactuating the reed switch an indicating a reduced or no flow situation.

  • All models field adjustable

  • Deactuation (decreasing flow) averages 40% less than actuation (increasing flow).

  • Repeatability ±2%

  • Correction must be made for attitudes other than horizontal.

  • Unit will pass greater flows.

Corrections must be made for other gases, line pressure and temperatures. Please consult your representative or the factory.
