VA 570 - with integrated measuring section
Flow sensor VA 570 is supplied with an integrated measuring section. The measuring sections are available in flanged version or with R resp. NPT thread.
A special feature is the removable measuring head. So the measuring unit can be removed easily and quickly for calibration or cleaning purposes without having to dismount the measuring section intricately. During this period the measuring section is sealed by a closing cap (accessory).
The screwing with centring device ensures that the sensor is positioned accurately in the centre when screwing it into the measuring section furthermore it grants an exact positioning in the flow direction. This avoids unnecessary measuring faults.
The new flow sensors VA 550/ 570 works according to the calorimetric measuring principle. Therefore an additional temperature and pressure compensation is not necessary.
Due to its robust design, the aluminum die cast housing, the robust sensor tip made from stainless steel 1,4571, the new VA 550/ 570 are suitable for demanding industrial applications. An ATEX version is available for applications in explosive areas. For flow measurement e. g. of natural gas there is a version with a DVWG admission.
