KNAUER's Mini CORI-Flow (M13) Flowmeter

Mini CORI-Flow are precise and compact mass flowmeters and controllers, based on the Coriolis measuring principle. Coriolis flowmeters are unmatched in accuracy. When applied for liquids, the mass flow accuracy is better than ±0,2% Rd.

Instruments of the mini CORI-Flow series contain a uniquely shaped, single loop sensor tube, forming part of an oscillating system. When a fluid flows through the tube, Coriolis forces cause a variable phase shift, which is detected by sensors and fed into the integrally mounted pc-board. The resulting output signal is strictly proportional to the real mass flow rate. The mini CORI-Flow features density and temperature of the fluid as secondary outputs.

Key Features

  • direct mass flow measurement
  • independent of fluid properties
  • high accuracy
  • excellent reproducibility
