Flow Instruments

Flow switches

Flow switches are used for the display and monitoring of the flow of liquid and gaseous media. The instruments feature a high switching accuracy and functional safety, low switch hysteresis and continuous switch point setting by the operator.

The wide selection of WIKA flow switches also includes viscosity-compensated models and ATEX-certified instruments for use in hazardous environments.

 

Float switch for the process industry, lateral installation with external chamber

Typical model: ELS

Special features:

  • Freely selectable switch position through fixing the float switch at the required level
  • Large range of application due to the simple, proven functional principle
  • For harsh operating conditions, long service life 
  • Operating limits:
    - Operating temperature: T = -30 ... +150 °C
    - Operating pressure: P = Vacuum up to 40 bar
    - Limit density: ρ ≥600 kg/m3

Application:

  • Mounting on engines, tanks, vessels or enclosures, where, due to a lack of space, installation within them is not possible
  • Use for turbulent liquid levels such as in oil sumps in large engines, gearboxes etc.
  • Pump and level control and monitoring of distinct filling levels
  • Chemical, petrochemical industry, natural gas, offshore, shipbuilding, machine building, power generating equipment, power plants
  • Process water and drinking water treatment
