Flow sensor VA 420 with integrated measuring section
Flow sensor VA 420 with integrated measuring section
Available with and without flange. The affordable flow meters VA 420 work according to the approved calorimetric measuring principle. Due to its compact design it is possible to monitor all compressed air systems from the compressor to the smallest compressed air tool (1/4“ to 2 inch) with the affordable flow meter VA 420.
Application range of VA 420
- Compressed air balancing, compressed air consumption measurement
- Leckage air / leak rate determination
- Mobile compressed air measurement in front of single machines/plants
- Flow measurement of process gases like e.g. nitrogen, CO2, oxygen, argon, nitrous oxide
- Flow measurement at nitrogen generators
Stationary use
For stationary use there are the following outputs available for the data transfer to a building management system or PLC: 4...20 mA for actual flow. Pulse output (galvanically separated) for the total consumption.
Mobile use
By means of quick couplings the flow meter can be integrated quickly into the feed hose of a machine. During the shutdown of the machine it is possible to determine the leak rate, the actual flow can be obtained when the machine is running. The power supply is effected via the power socket by means of the mains unit. For data recording over a longer period of time we recommend to use the compressed air analyzer DS 500 mobile or DS 400 mobile.
