Description

Features:
  • Close on-off differential
  • Low maintenance
  • Visual indication of flow with acrylic model
  • No seals
  • In line vertical plumbing
  • Materials: Acrylic, brass, 316SS, or teflon
  • Confirms: Normal flow condition
  • Senses: High flow and low flow conditions
  • Output: Switch contact
Applications:
  • Analyzers
  • Kidney dialysis machines
  • Micro biomedical
  • Laser cooling systems
  • Bubbler systems
  • Pollution sampling equipment
Operations:

When air/water flows through the unit it causes the magnetic piston to move up at the calibration point. This displacement is caused by the pressure differential from the air/water flowing through the unit. The magnetic piston actuates a hermetically sealed reed switch, which is encapsulated in the body of the unit, out of the air/water path. Decreasing the flow below the calibration point causes the reed switch to de-actuate.
  • Actuation points for air at 68° F and 14.7 psia with increasing flow
  • Deactuation (decreasing flow) averages 10% less than actuation (increasing flow)
  • Flow setting accuracy ± 10% of calibration points shown
  • Repeatability ±1%
  • Unit will pass great flow
