Warning Messages
W1: CHECK SITE DATA
This message occurs when the application information has been entered incorrectly and the wrong sensors have been
attached to the wrong pipe size causing the system timing to be in error. The site data needs to be checked and the
instrument reprogrammed.
W2: SIGNAL TIMING POOR
Unstable signal timing or differing up/down stream times indicate that the liquid is aerated or pipe surface is of poor
quality.
W5: FLOW SIGNALS POOR
This warning appears when there is a signal lower than 25%. This could be due to the application, a poor quality pipe,
amongst others.
W6: mA OUT OVERANGE
The mA output is over-range when the flow is higher than the maximum mA range. Once the
4-20mA has been set up and the flow goes above the range set then this message will appear. It is possible
to re-scale the 4-20mA to be able to cope with the higher flow.
W7: BATTERY LOW
The battery low warning occurs when battery indication is on 40%. The instrument has approximately 30 minutes usage
before it needs recharging. (See application note at the back of this manual)
W8: mA LOAD TO HIGH
The 4-20mA Output is designed to work with a load up to 750
Ω
. When the load is too high or not connected, the above
warning message will be displayed.
Other Messages
The messages below appear mainly when data has been incorrectly entered or the Portaflow 216 is trying to be used on
an application that it is not capable of working on.
Pipe OD out of range
The outside diameter of the pipe has been entered and is out of range of the instrument.
Wall thickness out of range
The wall thickness that has been entered is out of range of the instrument.
Lining thickness out of range
The pipe lining thickness has been incorrectly entered.
Site range is 0 - 20
There are only 20 storage sites available with 0 being the QUICK START site.
