Biotech Liquid Flow Meter

Biotech Liquid Flow Meter

Measures continuous flow rates without interference in your fluidic systems

Our new Digital Liquid Flow Meter continuously and accurately determines inline flow rates in various applications including liquid chromatography, Peristaltic pump monitoring, Flow chemistry, and Process flow applications.

It is very easy to use, small enough to fit in your hand or lab coat pocket – and weighs less than your cell phone! Our Liquid Flow Meter comes pre-calibrated and can be connected inline in any orientation to continuously measure flow rates. Discover Precision with our Advanced Liquid Flow Meter Series.

Our innovative technology ensures uninterrupted measurement of flow rates, setting a new standard for accuracy and reliability.

Key Features:

1. Uninterrupted Measurement: Experience continuous flow rate monitoring without interference in your fluidic systems. Our Flow Meter series guarantees precision without disruptions.

2. Digital Calibration for Accuracy: Delivered digitally calibrated with a certificate of conformity, our Flow Meters offer superior precision and accuracy across a broad measurement range. Gain improved results with high-quality, reliable measurements for your fluidic system.

3. User-Friendly PC App: Interact seamlessly with our specially designed app for easy control and monitoring. Record and store flow rates continuously, with the flexibility to set integration times from continuous reading up to 10 seconds. Via its USB interface and modern PC application, data is recorded as a time series, which is helpful when troubleshooting pumps, check valves or other malfunctioning components in liquid chromatography equipment.

4. Versatile Solvent Options: Choose from five pre-calibrated solvents or add your own, providing flexibility for various applications. Our Flow Meters come in four different versions, catering to flow rates ranging between a few nl/min up to 650ml/min.

5. Reliable Trouble-Free Operation: Engineered for ultra-reliable performance, our Flow Meters are suitable for virtually any flow application. Micro- and HPLC-flow versions are compatible with standard GPC/HPLC solvents.

6. Application Areas:

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

7. Wide Compatibility: Designed for continuous flow rate measurement, our Liquid Flow Meters are compatible with a wide range of solvents/pH and pressures up to 3 MPa (435 psi). Perfect for high-precision measurements ranging from 1-80µl/min up to 650 mL/min.

8. Full Control with App: Take charge of your fluidic system with our included app, ensuring comprehensive control and monitoring capabilities. It elevates your fluidic system’s performance with our Liquid Flow Meters – where precision meets innovation.
