8. Electrical Connection
Note! Ensure that the voltage levels of your supply system are in agreement
with that of flow meter.
· Make sure that the electric supply lines are not active.
· Join the connection cable with your power supply cable, according to the
connection plan shown below.
· We recommend a cross-sectional area of 0.25 mm² for the power supply
cable.
Warning! A false connection of cable can lead to destruction of unit's
electronics section
