Biotech Liquid flow meter

Biotech Liquid Flow Meter
Measuring without
interference in your fluidic systems

Biotech is proud to introduce a new Flow Meter series which enables continuous measurement of flow rate, without interference in fluidic systems.
A modern PC based App allows continuous recording and storage of the measured flow rates.

Improved Results
  • Supplied digitally calibrated with a certificate of conformity, our range of flow meters deliver high-precision and accuracy across a wide measurement range.
  • Monitor your fluidic system and get pump performance diagnostics at the same time!

Ease of use
  • Use the specially designed app for easy interaction and control.
  • Save the data to your system
  • Set the integration time - from continuous reading up to 10 seconds
  • Choose between 5 different pre-calibrated solvents or add your own
  • 4 different versions for flow rates ranging from a few nl/min up to 650ml/min

Reliable Trouble-free Operation
  • Our ultra-reliable flow meters are suitable for virtually any flow application.
  • The Micro- and HPLC-flow versions are compatible with all standard GPC/HPLC solvents.

Application Areas
  • Chromatography – validation & diagnostic purpose
  • Peristaltic pump monitoring
  • Flow chemistry
  • Process flow applications
  • And more…

The Biotech Liquid Flow Meters are specifically designed for continuous measurement of flow rates. Compatible with a wide range of solvents/pH and pressures up to 3 MPa (435 psi), it is the perfect tool for high-precision measurement of flow rates ranging from 1-80µl/min up to 650 mL/min.
With the included app you will be able to take full control of your fluidic system.
