Empty pipe trigger level is the threshold limit that the empty pipe value must exceed
before the empty pipe diagnostic alert activates. The default setting from the factory is
100.
Empty pipe (EP) counts
LOI menu path Diagnostics → Basic Diag → Empty Pipe → EP Counts
Limits: 2 to 50
Empty pipe counts is the number of consecutive updates that the transmitter must receive
where the empty pipe value exceeds the empty pipe trigger level before the empty pipe
diagnostic alert activates. The default setting from the factory is 5.
9.4.2 Optimizing tunable empty pipe
The tunable empty pipe diagnostic is set at the factory to properly diagnose most
applications. If this diagnostic activates, the following procedure can be followed to
optimize the empty pipe diagnostic for the application.
1. Record the empty pipe value with a full pipe condition.
Full reading = 0.2
2. Record the empty pipe value with an empty pipe condition.
Empty reading = 80.0
3. Set the empty pipe trigger level to a value between the full and empty readings.
For increased sensitivity to empty pipe conditions, set the trigger level to a value
closer to the full pipe value.
Set the trigger level to 25.0
4. Set the empty pipe counts to a value corresponding to the desired sensitivity level
for the diagnostic.
For applications with entrained air or potential air slugs, less sensitivity may be
desired.
Set the counts to 10
9.5 Electronics temperature
The transmitter continuously monitors the temperature of the internal electronics. If the
measured electronics temperature exceeds the operating limits of –40 to 140 °F (–40 to
60 °C) the transmitter will go into alarm and generate an alert.
