Flow management and suction lift verification of small work piece are possible

High accuracy: Max. ± 3% F.S.
Precise flow measurement is possible.
Quick response time: Max. 50 msec.
High-speed response is realized by incorporating a platinum sensor chip processed with silicon micromachining and contributes to shorten cycle time.
Built-in needle valve model
Flow adjustable needle valve and sensor are integrated into one unit. Easy piping and space saving.
Bi-directional flow measurement is possible
Bi-directional flow model allows for pre-setting the flow direction as desired, which gives you installation flexibility. It can be used as a reverse flow detector.
Convenient display function is provided
Reversible display function allows the orientation of display to rotate when the sensor is used upside down.
2-color/dual display contributes to enhancing operability
Operability is enhanced by the dual display. 2-color display allows for detecting abnormalities at a glance.
Flexible mounting options
By a mounting bracket, a panel mount bracket or a DIN rail mount bracket
No straight piping section required
No straight piping section is required at either upstream or downstream side.
A variety of connections
Inch sizes are newly added.
Setting copy function is equipped
Settings on master sensor can be copied to slave sensors.

Note	1. Use dry gas which does not contain corrosive elements such as chlorine, sulfur or acids, and which is clean and does not contain dust or oil mist. When using compressed air, use clean air that complies with JIS B 8392-1:2012 Class 1.1.1 to 1.6.2. Compressed air from the compressor contains drain (water, oil oxide, foreign substances, etc.). To maintain the function of the product, install a filter, air dryer (min. pressure dew point 10°C or less), and oil mist filter (max. oil content concentration 0.1 mg/m³) on the upstream side of the product. 2. Compressed air is used for adjustment and inspection of this product. Accuracy for gas types other than air is only a guide. 3. The accuracy is based on the manufacturer's standard flow rate meter. It does not represent absolute accuracy. Repeatability, temperature characteristics, and pressure characteristics are not included in accuracy ± 3% F.S. Take a nessessary step depending on the operating environment and conditions. 4. Repeatability is calculated during a short period of time. Aging variation is not included. 5. Actual response time may differ depending on piping conditions. Response time can be set within the range of 50 msec. to 1.5 sec. 6. The output impedance of analog output type is about 1kΩ. In the case the impedance of the connecting load is low, output and error increase. Check error with the connecting load before using. 7. The power supply voltage specifications differ for the voltage output type and the current output type. 8. Current when 24 VDC is connected and no load is applied. The current consumption will vary depending on how the load is connected. 9. The gas type switching function enables it to switch to argon, carbon dioxide, argon 80% + carbon dioxide 20%. The details are as follows. Note that the full scale flow rates become half of those of the flow rate range when switching to carbon dioxide gas. 10. The protection circuit of this product is effective only for specific error connections and load short-circuits. It does not provide protection for all misconnections. 11. The product measures changes in heat distribution caused by flow. If installed vertically, the heat distribution may change due to theeffect of convection, and the zero point can shift. 12. Accuracy may be affected by the piping conditions. For more accurate measurement, provide a straight pipe section 10 times as long as the pipe inner diameter.
