LIQUI-FLOW™ mini - Microfluidic Mass Flow Meters

Ultra Compact Liquid Mass Flow Meters Based On Thermal Flow Measurement

LIQUI-FLOW™ mini are very compact Liquid Flow Meters for ultra low flow ranges. The instruments operate on a thermal, thru-flow measuring principle, using a straight, duplex steel sensor tube with a very small internal volume (0,88 mm3, smaller on request).

  • Lowest range 1,5 ... 75 mg/h
  • Highest range 12 ... 600 mg/h (fluids with thermal properties similar to IPA/H2O)

Micro fluidic concept

The use of micro fluidic devices for research and analytical purposes has some important advantages. Firstly, because the internal volumes within the instruments are very small, the analysis will be faster and the amount of reagents and analytes used can be reduced. The latter is especially significant for expensive reagents. Furthermore, the physical dimensions are much smaller than those of conventional devices. This enables Life Sciences system integrators to downscale the size, inherently reducing the costs of ownership, of their equipment. Also, the availablility of compact and lightweight instruments could lead to the development of portable systems.
