6. Troubleshooting
Symptom
Cause
Solution
No LCD Display
Power supply too low
Ensure >10VDC supply
connected
LCD stays displaying u 3-01 or 3.2.38
or similar
Failure of unit to boot main
Operating System
Disconnected PCB to
display
Disconnect power and USB
If restart fails to resolve PCB
requires replacement
“FLUID” Shown on LCD Display on
meter or in Titan Interface Software
No fluid in the meter
Check meter for fluid supply
Fluid back pressure too low Increase Back pressure on
meter

NOTE: For low signal fluids the Limit Gain can be unticked
on the advanced tab.
Erratic/ Incorrect Flow Reading
And/or Loss of accurate flow at top
end of meter flow range
Signal too weak
Check Advanced Tab for
signal strength
Back Pressure too low for
adequate signal
Increase Back Pressure to
2.x.vapour
pressure of the liquid
Gas in flow meter
Increase flow to purge line
Ensure position optimum for
ensuring no gas can be
entrained in the flowmeter
Erratic or Cycling Flow Rates at
constant liquid flow
Pulsating flow causing
aliasing of the flow meter
sampling in relation to the
flow pulsation
Remove or Dampen
pulsation to below 10Hz
Noisy flow reading at low flow
Gas in flow meter
Increase flow to purge line
Ensure position optimum for
ensuring no gas can be
entrained in the flowmeter
T
otal or Batch Flow Continues to rise
even though no flow through the
meter
B
ackground noise is giving
a small flow signal to the
meter
Increase the Cut Off setting
to ensure any noise-induced
signals are set to zero flow
Flow reading incorrect after period of
shut down
Flow Signal incorrectly
positioned due to air in
meter or background noise
Reset the meter
