6.3 Tunable empty pipe detection
The tunable empty pipe detection provides a means of minimizing issues and false readings when
the pipe is empty. This is most important in batching applications where the pipe may run
empty with some regularity. If the pipe is empty, this diagnostic will activate, set the flow rate to
0, and deliver an alert.
Turning empty pipe on/off
The tunable empty pipe detection diagnostic can be turned on or off as required by the
application. The empty pipe diagnostic is shipped turned “On” by default.
6.3.1 Tunable empty pipe parameters
The tunable empty pipe diagnostic has one read-only parameter, and two parameters that can be
custom configured to optimize the diagnostic performance.
Empty pipe (EP) value
This parameter shows the current empty pipe value. This is a read-only value. This number is a
unit-less number and is calculated based on multiple installation and process variables such as
sensor type, line size, process fluid properties, and wiring. If the empty pipe value exceeds the
empty pipe trigger level for a specified number of updates, then the empty pipe diagnostic alert
will activate.
