Characteristics
Built-in needle valve model
Flow adjustable needle valve and sensor are integrated into one unit. Fuss-free plumbing and minimized installation space are
realized.
Panel mount is possible.
Bracket for panel mount is available.
Sensor as well as built-in needle valve sensor can be panel mounted.
Since coherent installation is possible, one large panel cut make possible for mounting multiple sensors with minimum space
and process.
Dual display / 2 color indication feature
Introduction of main and sub display improve operability.
Additionally, 2 colors indication makes easy cognition of error.
High accuracy, Max.±3%F.S.
Accuracy of ±3%F.S is realized, and precise ow measurement is possible.
Coherent installation is possible

Bidirectional ow measurement is possible.
Bidirectional ow model can measure the ow of preset direction. Flexibility of the plumbing installation improves and usable for
reverse ow detection.
Free installing orientation
The sensor can be mounted in any orientation: top, bottom, left, or right.
Quick response time, Max. 50msec.
High-speed response is realized by incorporating a platinum sensor chip processed with silicon micromachining. It contributes
to shorten takt time.
No straight piping requires
The newly proposed rectifying structure eliminates the need for a straight piping section upstream or downstream.
Forward direction Bidirectional Reverse direction
Elbow plumbing is possible.

*1. Converted to volumetric ow at 20˚C and 1 atmospheric pressure (101kPa)
*2. Displayed ow rate less than approx. ±1% F.S is rounded down (zero adjusted).
*3. Accumulated ow rate is a calculated reference value and reset when shut down.
*4. When owing compressed air, please use a clean air conforming to JIS B8392-1:2003 Grade 1.1.1 ~ 1.6.2. Please install a lter (ltering rate: 5µm), an air dryer
(minimum pressure dew-point: max 10°C) and an oil mist lter (max oil content: 0.1mg/m³) onto the primary side (upstream) of the sensor since the compressed
air from the compressor contains drain (water, oil oxide and foreign material, etc.)

Some functions and settings are completed when the normal ow is displayed, and some after entering setting mode. The setting mode is
divided into standard setting mode and detailed setting mode based on the frequency of use.
■Explanation of function
●Normal operation
Item Description Default setting
Real-time flowdisplay Real-time flowrate is displayed. −
Accumulated flowdisplay
It can be changed to accumulated flowdisplay.
The switch output function includes turning the switch ONand OFF when the
specified accumulated value is exceeded, and an accumulated pulse function
that outputs a pulse after a set count value. It will be reset if power is turned
off and can be reset with button operation or external input.
Real-time flowdisplay
Peak hold function Maximum and minimum flowrates within a set interval are displayed. Peak hold OFF
Key lock function Key operations are disabled to prevent incorrect operation. Key lock invalid
Error display function. The status of errors is displayed when trouble or error occurs. −
●Standard setting mode
Item Description Default setting
Switch output function Having 2points switch output, 7 operation patterns and operation stop can
be set.
Both CH1and CH2are
set to switch OFF
Forced output function Switch output is forcibly turned on to check line connections and default
operation of the input device. −
Zero adjust function Zero point deviation is corrected. (Range : 0±10%F.S.)Adjusted value: 0

●Detailed setting mode
Item Description Default setting
Selection of flowdirection
(available only on bidirectional
model)
The flowdirection is set to bidirectional, one-way forward direction, or one-
way reverse direction. Bidirectional
Select CH2operation
Select CH2function.
Select whether to use CH2as switch output or as external input (accumulated
value reset/auto reference).
Switch output
Auto-reference function
When CH2is set to auto-reference, the threshold of switch output can be read
by external input or button operations. The threshold is changed automatically
when the threshold of switch changes.
Auto-reference function
OFF
Response time setting The response time is set in 7 stages from max.50 ms to 1.5s. Chattering or
incorrect operations caused by abrupt flowchange or noise are prevented.
Response time : Max.
50ms
Display speed setting The digital display's update cycle is set in 3stages from 250 ms to 1sec.
Display blinking is minimized by making the display update cycle longer. Display speed: 250ms
Sub display setting Set the sub display indication selecting from flowdirection, flowunit, or fluid
medium display ("Ai" for air or N2)type. Flowdirection
Display color setting Set the display color.
The display color is set for the normal display and switch output ON.
For both main and sub,
Normal display: green,
Switch ON: red
Hysteresis setting Set hysteresis of switch setting value.
Use this if flowpulsates and the switch chatters near the threshold. Hysteresis: 1% F.S.
Flowunit setting
Select the display unit from the standard state or reference state.
Standard state (ANR): Flowconverted to volumetric flowat 20°C & 1
barometric pressure
Reference state (NOR): Flowconverted to volumetric flowat 0°C & 1barometric
pressure (*1)
Flowunit: ANR
ECO MODE setting
ECO MODE is selectable.
If no button is pressed for one minute, the mode changes to ECO and the
backlight turns off, minimizing current consumption.
ECO MODE OFF
Reset settings Settings are set to the default. −
*1. The reference status display is a calculated (reference) value.

■Auto-reference function
When CH2 is set to auto-reference, the threshold of switch output can be read by external input or button operations. The threshold is changed
automatically when the threshold of switch changes, such as when workpiece changes. The input value is the ow rate when the external input
is turned ON.
The switch setting of CH2 is disabled during auto-reference operation.
