Unusual or faulty conditions
If you continue using our product under the unusual or faulty connections or
conditions like as smoking, foul smell, unstable and malfunction, it could cause
fire or accident. Cut the power supply immediately and contact to us. Do not try
to repair the product yourself.
Working environments
In the humid or dewing environment, it could cause accident or damage because of moisture.
In the vibration, impulsion or pulsation environment, it could cause malfunction,
some accident or damage.
Our products are NOT explosion-proof. Do not use in the dangerous environment with
flammable, explosive, or corrosive gas.
Do not use outside. This product is only for inside.
Installation in high temperature environment as near to heat instruments could
cause some accident or damage as the heat instrument will led the temp rise inside
the flow meter. Please use our product as instructed in the manual.
Caution
Cables
Please do not put heavy objects on the cables or pull the cables from flow
meter body, it could cause accident or damage.
Please follow the Instructions for
it could cause accident or damages.
Working environments
Magnetic power, electromagnetic wave, radioactive ray or ultraviolet rays
could cause accident or damage.
Electric corrosion or static electricity could cause accident or damages.
In electrically noisy environments as like around high-frequency power
source could cause accident or damages.
Install the filter upper flow/Inlet to clear some piece of metal or small
objects if needed.
Remove the bubbles in the fluid for accurate measurement of flow rate.
Packaging and carrying.
Do not drop ,Handle with care otherwise The flow meter could damage or
cause malfunctioning.
Installations
Mind your fingers while plumbing a sensor or you could get injured.
Maintenance
Contact us for overhauling, adjusting or repairing. Please make sure not
to touch an electronic substrate inside of flow meter.
Only a person who has technical knowledge and experiences could do
plumbing, wiring, maintenance or overhauling.
while installation or maintenance please shut off the power and water
supply for your safety.

Features
Karman vortex flow meter
J PSL-5L/10L/30L is the new
series of flow meters to measure
flow rate, with simple functions
and reasonable price.
Due to compact construction it
can be installed in narrow space
and simple structure resulting
easy maintenance, easy
installation and de-installation.
Never do it.
Do it only with following instructions.
