  • Page 4: General

    VFM-60 Vortex Flowmeter 1 General Every VFM60 vortex flowmeter will be carefully inspected before delivered to users. Please carefully check if there is any damage on the package and product when you received them Please check if the package contains all the accessories according to 1.2 or your purchase order. Please make sure the person in charge of this device has carefully read this manual and understand its descriptions.

  • Page 5: Measuring Principle

    VFM60 series digital vortex flowmeter is designed to provide most reliable performence. This series of vortex flowmeter is designed on PA60 plateform. Every part utilized is universal for all VFM60 series products. The circuit boards use signal isolation and self-diagnose technology. VFM60 series utilize spectrum analizing signal process technology, which ensured lower under measuring limit and better turndown ratio.
