(1) Process fluid flowing in same direction as flow direction arrow on sensor.
(2) Applies only if the discrete output has been configured to indicate flow direction. See Section 6.7.2.
(3) Refer to the digital communications status bits for an indication of whether flow is positive or negative.
(4) Process fluid flowing in opposite direction from flow direction arrow on sensor.

Configuring events

An event occurs if the real-time value of a user-specified process variable varies above or below a
user-specified value, or inside or outside a user-specified range.
Events can be used to initiate specific transmitter actions. Possible actions include:
• Start zero
• Reset mass total
• Reset volume total
• Reset gas standard volume total
• Reset all totalizers
• Start/stop all totalizers
Up to five events can be configured. You can define more than one event on a single process variable
if desired.
You can configure an event to initiate multiple actions, e.g., you can configure Event 1 to reset both
the mass total and the volume total.
