  • Page 3: Flowmeter Check

    3. Working Principle ALIA AVF7000 is newly stress-type flowmeter that’s based on von Karman effect. It’s made up of a whole body whose internal diameter and nominal diameter are the same and a triangular bluff body inside. Flow will alternately generate vortices when passing by a bluff body.

  • Page 6: Installation

    AVF7000 Operation Manual OP7000.1.1.7.R12ENG 6. Installation Installation position of Vortex Flowmeter is very important. It concerns measuring accuracy. Please leave more space of straight pipe in upstream and downstream as best as you can. If not permitted, please install as 2/3 of total straight pipe length on the upstream and 1/3 on downstream.
  • Page 7 AVF7000 Operation Manual OP7000.1.1.7.R12ENG ● Grounding Good grounding is highly demanded so as to avoid signal interference. Please see below pictures, all you need to do is to ground the displayer. And the sensor grounding is unnecessary. Grounding place is like stairs and railing. To define whether vortex is well grounded initially, user need to check whether frequency is 50HZ or 60HZ or not.
