3. INSTALLATION
Please slope the conduit pipe down, and install a drain
valve at the low end of the vertical pipe.
Please open the drain valve regularly.

CAUTION
All the devices to be connected to current
output and pulse output must be conformed to
CSA1010, CSA950, or IEC950.

(2)Pulse Output
IMPORTANT
Please give attention to voltage and polarity in
wiring, because it is transister contact (insula-
tion type.)
• In case of the filtering constant of Electric
Counter is more than the pulse width, it makes
signal decreases and can not be calculated
correctly.
• In case of input impedance of electric counter
is large inductive noise from power supply
bring bad influence to measurement. To
calculate correctly, it is recommended to use
shield cable or to make input impedance small
enough within the limits of pulse output of
flowmeter.

(3)Alarm or Status Output
IMPORTANT
This is a transistor contact(insulated type) so
attention must be paid to voltage and polarity
when making connections.
This output can not switch an AC load. To do
this, another relay (see the figure below) is
required.
* The alarm output works from "close"(Normal) to
"open"(Alarm).
