LIQUI-FLOW™

LIQUI-FLOW™ THERMAL MASS FLOW METERS / CONTROLLERS FOR LIQUIDS

Through-Flow Measurement of Low Liquid Flow Rates

LIQUI-FLOW™ digital Liquid Flow Meters/Controllers for low flow ranges operate on a thermal, through-flow measuring principle. The instruments are equipped with a digital pc-board, featuring self-diagnostics, alarm and counter functions, digital communication (RS232) and a variety of fieldbus options.

• Lowest range 0,25 ... 5 g/h
  
• Highest range 20 ... 1000 g/h for fluids with thermal properties similar to H2O
