caloric flow controller EFK -  Greisinger electronic

caloric flow controller

properties:

The flow controllers EFK... monitor liquids and gaseous substances.
The instrument combines compact dimensions with a integral probe, a LED
tendency display (for FLOW) with dual-colour status indicator and an output,
whose switch-point can be adjusted via a potentiometer.

  • no moving parts in the monitored medium
  • mounting largely independent on pipe diameter
  • low pressure loss
  • high working pressures (up to 100bar)

area of application:

  • metal processing industry: monitoring of cooling liquids and lubricants
  • steel industry: coolant circuits
  • chemical industry: protection against dry running (for pumps), detection
    of leakages and monitoring of fill levels
  • beverage industry: monitoring of cleaning processes

Sensors suitable for: water, oil, aggressive substances
