Durchfluss

All-metal variable area flow meter
Typ: BGF

The BGF measuring device is suitable for measuring the flow of liquid or gaseous products and steam in pipelines. The current flow rate is displayed in volume or mass per unit of time.

Due to its design, the BGF is particularly suitable for processes under difficult and harsh operating conditions. Any flow direction offers expanded application options.

Details

Applications

Measurement of liquids and gases (e.g. argon) in pipelines.
Display of the current flow rate in volume or mass per unit of time.

The devices are available with additional electrical equipment for process monitoring and control.

  • Permanent magnetic transmission of measured values
  • Use for high pressure applications and high fluid temperatures
  • Excellent heat tracing techniques (optional)
  • Double eddy current damping (optional)
Reliability

Particularly suitable for processes under difficult and harsh operating conditions due to its robust design.

Special features
  • Horizontal installation possible, so can be used for all flow directions
  • Clear 90° scale.
  • Linear characteristic curve thanks to optimized float shape.
  • High temperature versions up to 200°C
  • High pressure versions up to 600bar
  • Large selection of materials in contact with the product
  • Tear-proof magnetic measured value transmission
  • Gas or liquid damping (optional)
  • Excellent heat tracing techniques (optional)
