Gas flow meter
Calibration standard for low flows
Our ReciFlow™ is an extremely accurate flow meter for gases. The measurement principle is based on a proven technique of a flow-through piston. The gas flow meter is characterized by high measurement accuracy and reliability!
|Flow range*||0.5…500 ml/min|
|Accuracy volumetric||±0.3% MV +0.006 ml/min|
|Accuracy norm volume flow**||±0.4% MV +0.006 ml/min|
|Reproducibility||±0.15% MV +0.002 ml/min|
|Pressure range||0.25…2.5 bar|
**Ambient temperature range 20.24 °C and pressure range 950..1050 mbar absolute.
Outside this specification, the measuring accuracy must be corrected by 0.1%.
The long-term stability (1 year) of ± 0.1% is included..
Position of piston is measured continuously. Direction of piston movement is controlled by valves 1 and 2. The piston reciprocates in the tube, making the measurement continuous. A bypass valve 3 is opened when the instrument is shut down. Valves 1 and 2 are used to shut off the flow when in dosing mode.
- Continuous measurement
- Faster and more reliable calibrations
- Flexible adjustment of the flow volume
- Easy to use intuitive touch panel user interface
- Large pressure range that is not limited to ambient pressure
