This product is suitable for Class I and Class II
applications only, per the requirements of
standard EN60730 and any additional specific
requirements for a particular application or
medium being sensed. Class I compliance of
metal bodied units requires a ground connec-
tion between the metal body and the earthing
system of the installation. Class I compliance of
plastic bodied units in contact with a conductive
medium requires that the medium be effectively
earthed so as to provide an earthed barrier
between the unit and accessible areas. For
Class III compliance, a supply at safety extra-
low voltage (SELV) must be provid-
ed. Please consult the Factory for
compliance information on specific
part numbers.

+VDC Red
Ground Black
Signal Output White
Signal Output: Output signal is an on/off
pulse of the DC voltage supplied to the
unit. It is compatible with all digital logic
families. Input voltage range is 4.5
to 24 VDC. Frequency of the output pulse
is proportional to the flow rate and ranges
from approximately 15 Hz at low flow to
225 Hz at high flow.
