For recalibration of the VA 570 it is not necessary to remove the complete measuring section. It is sufficient to depressurize the line, unscrew the sensor from the integrated measuring section and close it with a sealing cap. Likewise, a replacement sensor could be used for the duration of the recalibration.

Die Rekalibrierung des VA 570 ist somit mit einem geringen Aufwand verbunden als mit herkömmlichen Durchflusszählern.

In most cases, the compressed air is not free of oil, condensate, dirt and particles. Over time, this leads to contamination of the consumption meters and thus to measurement errors and even total failure. Consumption meters currently on the market cannot usually be cleaned on site, but are replaced when they become contaminated.

The VA 570 is different and can be easily cleaned on site. For this purpose, it is simply shaked in water or non-aggressive cleaning agent to remove coarse dirt.

A positive-locking connection ensures precise alignment in the measuring section during reassembly.

The robust stainless steel sensor tip is ideal for harsh industrial conditions. It is protected against mechanical damage during installation or removal. The covered sensor tips of the flowmeter provides protection against dirt particles, rust or other mechanical abrasion of the compressed air lines. All wetted parts are made of stainless steel, making the VA 570 an option for applications that have high surface finish requirements as well as cleanliness.

All necessary settings during initial installation can be set on site via the keypad. These include the selection of the unit, resetting the main counter, zero point adjustment or a low flow cut off, reference conditions, etc.

If the installation situation does not allow the display of the VA 570 to be seen, it can be mechanically rotated by 345 ° on site. Furthermore, the display can be digitally rotated via the menu keys, e.g. if the sensor is installed upside down.

This means that the measured values can be viewed in any installation position.
