Straight pipe length not
enough or the inner
diameter of flowmeter
pipe body do not match
the pipeline
Check the straight pipe length
and the diameter of the pipelien
Re-locate the flowmeter
There is heavy vibration
on the pipe line
Sense the vibration on the pipe
line by touch it with hand
Tighten the pipeline where
the flowmeter is installed
The fluid has not fill the
pipeline fully
Check the fluid status and the
location of the meter.
Re-locate the flowmeter
Two phase flow
Check if there is 2-phase flow
according to the pressure and
temperature of the fluid.
If the fluild is liquid-solid
two phase flow, need to
install a filter at upstream
of the flow meter. If the
fluild is liquid-gas two
phase flow, need to install
a getter at upstream of the
flow meter.
Transmitter failure
Replace the transmitter with
another transmiter of same type
to check
Replace the transmitter
There is big
difference between
the flow reading
and the process
flow rate
No density
compensation for steam
measurement
Check the density compensation
devices and the setting
Fix density compensation
The estimated flow rate
before using the meter is
wrong
Use other flowmeter to confirm
the actual flow rate
Setting incorrect
Check the settings of meter K
factor,upper and lower limit of
flow rate
Set the meter correctly
Note 1: Enter code setting, set C49=12. Press “U-D button” to check the current energy of vortex flow
signal and vibration signal. E1 is the energy of vortex flow signal, please set the energy threshod value
lower than the displayed value. E.1 is the energy of vibration, please set the energy threshod value
lower than the displayed value. Set above value in D017 (Energy threshold of vortex flow signal) and
D018 (Energy threshold of vibration), than set C49 back to 00.
9.3 Self-diagnose funcstion
VFM60 digital vortex flowmeter display can also indicate the self-diagnose code as below
：
Error code
Problem
Repair
Err-003
Temperature sensor disconnected
Check Temperature sensor
Err-004
Pressure sensor disconnected
Check pressure sensor
Err-005
About to over total flow
This is a reminding message
Err-006
Display value over limit
The value is over the physical limit of the
display
Err-011
Supperheated steam temperature is over limite
Reduce the steam temperature
Err-012
Supperheated steam pressure is over limite
Reduce the steam pressure
Err-013
Button is pressed and hold for too long time
Check the button circuit
