	Item # 0695 0571, VA 570 Flowmeter with Integrated 3/4 Inch (In) Measuring Section
	Web Price QUOTE

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).
