Advanced Configuration Functionality
Flow limit (1 and 2)
There are two configurable flow limits. Configure the parameters that will determine the criteria
for activation of a HART alert if the measured flow rate falls within a set of configured criteria.
This functionality can be used for operating simple batching operations or generating alerts
when certain flow conditions are met. This parameter can be configured as a discrete output if
the transmitter was ordered with the auxiliary output suite (option code AX) and the outputs
are enabled. If a discrete output is configured for flow limit, the discrete output will activate
when the conditions defined under mode configuration are met. See “Mode” on page 97 below.
Control
This parameter turns the flow limit HART alert ON or OFF.
ON - The transmitter will generate a HART alert when the defined conditions are met. If a
discrete output is configured for flow limit, the discrete output will activate when the conditions
for mode are met.
OFF - The transmitter will not generate a HART alert for the flow limit.
Mode
The mode parameter sets the conditions under which the flow limit HART alert will activate.
High and low limits exist for each channel and can be configured independently.
> High limit - The HART alert will activate when the measured flow rate exceeds the high limit
set point.
< Low limit - The HART alert will activate when the measured flow rate falls below the low limit
set point.
In range - The HART alert will activate when the measured flow rate is between the high limit
and low limit set points.
Out of range - The HART alert will activate when the measured flow rate exceeds the high limit
set point or falls below the low limit set point.
