【cable functions】
Contact between the spare wires or between wires and external equipment
could cause accident or damage. Please insulate each wire when used.
*1 Voltage more than specified on the table will damage the product.
Alarm output
The electric circuit, substrate, is attached on a wetted part of the body which
is covered with a cover. You find an alarm setting button and volume inside of the
cover, and a cables for interface on the side.
*Green LED will be on with analog output by power input.

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.
Mishandling could cause injury
or even death at drastic
conditions.
Mishandling could cause disability,
fire or other damages to the building
or properties.
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.
Our products are NOT explosion-proof. Do not use in the dangerous environment with
flammable, explosive, or corrosive gas.
In the vibration, impulsion or pulsation environment, it could cause malfunction,
some accident or damage.
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.
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 "wiring", "Output signal "other wise,
it could cause accident or damages.
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.
Do not drop ,Handle with care otherwise The flow meter could damage or
cause malfunctioning.
Mind your fingers while plumbing a sensor or you could get injured.
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.
Please contact us if you received damaged or deformed product.
