Consumption - VA 420 Consumption counter for compressed air and gases

Description

Verbrauchszähler VA 420  

Special advantages

• Measuring device removeable
• High measuring accuracy due to defined measuring section
• Easy installation into the existing pipeline
• 7 models from 1/4" to 2"
• Connecting thread DIN EN 10226 or weld neck flange DIN EN 1092-1
• Analogueoutput 4...20mA for actual consumption
• Pulseoutput for total consumption (counter reading)
• Compressed air counter up to  1,999,999,999 m3
• Compresssed air counter resettable to "zero" via keypad
• Units freely selectable via keypad
• Gas types adjustable via software

Due to its compact design it is possible to monitor all compressed air systems from the compresssor to the smallest compressed air tool (1/4 to 2 inch) with the new affordable consumption counter VA 420.
The installation of the compressed air counters VA 420 can be done easily and quickly. A special advantage is the removeable measuring device. The measuring device can be demounted for calibration or cleaning purposes without removing the complete measuring section.
