9.4 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
LOI menu path
Diagnostics → Diag Controls → Empty Pipe
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.
9.4.1
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
LOI menu path
Diagnostics → Variables → Empty Pipe
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.
