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.
- 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!
- 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
-
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.
- 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.
