Countermeasure
No output value displayed
with a flow.
Incorrect wiring.
Check the wiring diagram and correct the
wiring.
Incompatible power, voltage.
Check the power supply and voltage.
The tubing system is not filled
with the liquid.
Fill the liquid inside the tubing system.
The flow rate is outside the
measurable range.
Check the measurable range and choose the
product.
Output value displayed
without a flow.
The tubing system is not filled
with the liquid.
Fill the liquid inside the tubing system.
The liquid in tubes is
fluctuating due to large ripple.
Minimize the ripples by using dampers or similar
devices.
Large errors in
measurement detected.
Incompatible power, voltage.
Check the power supply and voltage.
Incompatible load resistance.
Use the load resistance of 500
Ω
or less.
There is noise-generating
equipment nearby.
Move the noise-generating equipment from the
vicinity.
There is flow-blocking
equipment nearest to IN side
of flowmeter.
Change the mounting position of flowmeter.
(keep the rated straight-tube length as follows)
IN side : 7 times longer than the bore
diameter
OUT side : 5 times longer than the bore
diameter
Cavitations are generated.
Keep the rated line pressure to prevent
cavitations.
There are bubbles contained
in the liquid.
Do tubing not to have mixed bubbles.
There are foreign substances
caught by shedder body.
Remove the foreign substances.
Notify your nearest sales office for problems not listed above.
