Medición en continuo del caudal másico de sólidos en transporte neumático en fase densa.

Especialmente desarrollado para medición de flujo de sólidos en transporte en fase densa.
El sensor mide la concentración y la velocidad del flujo sólido.

  • sin desgaste gracias a la vejiga de cerámica

También disponible para altas presiones hasta 110 bar.

  • Reliable flow metering in pneumatic dense-stream
  • Unlimited throughput volumes can be measured
  • Optionally pressure-resistant up to 25 bar
  • Installation creates no obstacle in the profile, hence no dead spots in which residue can form
  • Measurement independent of the flow speed of the material
  • Simple retrofitting
  • Maintenance-free
  • Contactless measuring procedure (no mechanics)
  • Materials: Powder or granules in pneumatic dense-stream transport in steel industry

In pneumatic dense-stream conveying , the installation point is specified in accordance with the conveyed inlet and outlet paths.

The assembly of the measuring tube at the specified installation point takes place using a flange installation. Measuring tubes can be supplied in standard form in nominal widths of up to 150 mm with flange connections in accordance with DIN 2576.
