Chapter 2. NAMES AND FUNCTIONS OF
PARTS
Wiring hole:
There are two wiring holes.
Insert the plug and seal packing
(provided) in the unused hole
Sensor/terminal section:
Houses the Micro Flow sensor chip
amplifier and wiring terminal plates.
Inlet:
This is where the fluid to be measured
flows in.
Flow path:
The fluid to be measured flows through
the flow rate.
Operation panel cover:
Open this cover to configure or reset
various settings.
ENT key:
Use this key to fix and store settings to
memory. Also use it to display total
flow rate, or to switch to the function
setup mode.
▲
key:
Use this key to increment a value.
▼
key:
Use this key to decrement a value.
Also use it to switch to the function
setup mode.
key:
Use this key to feed digits when changing setting
values. Also use it to move to the parameter
setup mode.
RESET key:
Use this key to reset alarms/integrated
flow rate.
Operation panel:
Use this panel to set functions,
parameters, alarms or alarm occurrence
wait time, and to reset alarms or reset
the integrated flow rate.
Display:
Displays the instantaneous flow rate
value, integrated flow rate value, total
flow rate value, function setting values
and parameter setting values on a in
7-segment LED display.
Outlet:
This is where the fluid
to be measured flows
out.
Alarm indicator:
Blinks when an alarm occurs.
Hi indicator:
Blinks when the upper limit alarm occurs.
Lo indicator:
Blinks when the lower limit alarm occurs.
DISP key:
Use this key to switch between instantaneous
flow rate display and integrated flow rate display,
and from setup mode to instantaneous flow rate
display.
▲
OVER indicator
Lights when the flow rate exceeds the
measurement range. Blinks when
the integration event occurs.
