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, refer to the product reference manual.
