EFK2
CALORIMETRIC FLOW SWITCH FOR LIQUIDS & GASES

  • Easy switch setting by potentiometer, a
  • dual colour LED and a Galvanic insulated switch signal
  • (NO) or transistor outputs (PNP/NPN).
  • Optional swan neck to achceive higher temperature ratings
  • Compact Flow Switch
  • No moving parts in the medium being monitored
  • Mounting largely independent of pipe diameter
MMF
FLOW METER FOR MEDICAL APPLICATIONS
  • MMF oxygen and airflowmeters offer economy,accuracy and reliability in an attractive, easy to use instrument.
  • Made with a high-impact resistant LEXAN flow tube,combinated with a sturdy machined brass base, these meters will stand up to the rigors of clinical or field use.
  • The durable stainless steelstem valve assures precisecontrol throughout the full flow range, and provides for positive flow shut-off.
