none-explosive environment.

Please make sure the environment the flowmeter in can meet the requirement of the certificate.

When power is wired, please make sure the front and rear cover is closed properly.

9.2 Troubleshooting and repair

Symptom

Reason

Trouble shooting

repair

No display

Power supply failure

Test the voltage on the power
source with a universal meter

Re-wire the power or use a
new power

Power is not wired

Test the voltage on the power
source with a universal meter

Wire the power

Cable if broken

Check if there is break off point
on the cable

Check the cable and
re-wire

Wrong wiring

Check if wiring to the correct
termimal

Re-wire

Displayed flow rate
is 0 while there are
flow in the pipe

Flow rate is lower than
the meter's lower limit

Increas the flow rate to check

Increase the flow rate or
replace a new proper
flowmeter

The flow rate of small
signal cut off function is
too high

Check the small signal cut off
setting

Set the small signal cut off
to a proper value

Energy threshold value
is too high

Check if the Energy threshold
value is too high in spectrum
analyzing checking mode

Set the Energy threshold
value to a proper value
(Please reference to Note 1
for how to set)

Transmitter function
failure

Replace the transmitter with
another transmiter of same type
to check

Replace the transmitter

Sensor is damaged

Increase the flow rate to check
first, than intall the transmitter
to another flowmeter in same
type to check.

Replace the sensor

Pipeline blocked or
sensor jamed.

If all above possibilties are
eliminated, please check the
pipe line and installation.

Re-install the flowmeter

The flowmeter has
flow reading while
there is no flow in
the pipe

Power frequency
interference

Check the frequency display on
meter is stable at the value that
same as the power frequency

Re-wire the meter with
sheilded cable according to
requirement.

There is high voltage
instrument or high
frequency interference
close to the flowmeter

Check if there is high voltage
instrument or high frequency
interference close to the
flowmeter

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

Valve is not closed
properly that there flow
leak into the pipe

Check pressure and check if
valve is closed and sealed

Repare the valve

The flow rate
reading fluctuate
significantly

The gasket and the pipe
are not concentric

Check the position of the gasket

Re-install the gasket

The flowmeter pipe
body and the pipe line
are not concentric

Check if the flowmeter pipe
body and the pipe line are not
concentric

Re-install the meter
