Description

Features:
  • Adjustable flow monitor
  • Monitors both gases and liquids
  • Materials: Brass or 316SS
  • Confirms: Normal flow conditions
  • Senses: High flow or low flow conditions
  • Output: Switch contact
Applications:
  • Process media
  • Fire control systems
  • Cooling systems
  • Heat pumps
  • Hydraulic lifts
  • Water treatment chemicals
Operations:

When flow is increased, the magnetic piston is forced against a bias spring. As the magnet comes near the adjustable reed switch it actuates, indicating proper flow. When flow decreases the spring forces the piston in the opposite direction deactuating the reed switch and indicating a reduce or now flow condition.

  • Actuation points for air at 68°F and 14.7 psia with increasing flow
  • Deactuation (decreasing flow) averages 40% less than actuation (increasing flow)
  • Repeatability ±2%
  • Unit will pass greater flows
