Basic Configuration
November 2019
Auto zero
The Auto zero is recommended for optimum performance when a flow meter is initially
installed, and it typically does not need to be performed again. However, if process
conditions drastically change, a new Auto zero is recommended. The sensor must be filled
completely with process fluid at zero flow. For more information, see
