• product specific scale and calibration, spring loaded
  
• intrinsically safe Exia or flameproof Exdb design
• local display with limit switch or 4-20 mA output
• largely independent of viscosity, low maintenance

Specifications

The 50 mm thick ring features a half-round plate that is fastened to a rotating spring-loaded spindle.

The angle between flap and ring changes according to the rate of flow, and a breakaway-proof magnetic coupling transfers the movement to an external pointer

• spring loaded flap connected to a 50mm ring
• flow direction: horizontal, top-bottom
• pipe size: DN 25 – 600
• flow up to 1650 m³/h (air 5000m³/h) 

The devices are used in water and waste water treatment plants, power stations, chemical and oleo-chemical factories, monitoring cooling and heating (furnace) systems, gravel extraction, etc.
