*1. Even instantaneous pressure fluctuation such as water hammer must be within the permissible pressure.
*2. The flow rate precision is defined based on the values measured in Omron's pre-shipment adjustment facility using
      water at the ordinary temperature (approx. 23°C).
      In the ordinary temperature environment (approx. 23°C), install the product with the long side of the chassis
      holding unit toward the upstream of the pipe.
      The measured value might vary due to fluid pulsation or pipe clogging.
*3. Cutting to zero is the function outputting the flow rate less than the minimum rated flow rate as zero.
*4. The ambient temperature characteristics are defined based on the values measured in the following environment
      using water at the ordinary temperature (approx. 23°C) flowing at 30 l/min.
      In ordinary temperature environment (approx. 23°C) / pipe diameter 20A / straight pipe length 200 mm or
      more / recommended joint (KITZ's PTZ-20A) / dedicated adapter (E8FC-YA-R20A) / Install the product with the
      long side of the chassis holding unit toward the upstream of the pipe.
*5. The temperature precision is defined based on the values measured in the following environment using water.
      In ordinary temperature environment (approx. 23°C) / pipe diameter 20A / straight pipe length 200 mm or
      more / recommended joint (KITZ's PTZ-20A) / dedicated adapter (E8FC-YA-R20A) / Install the product with the
      long side of the chassis holding unit toward the upstream of the pipe.
*6. If the pipe temperature exceeds 70°C, do not contact any cables with the pipe.
*7. Do not connect CH 2 (pin 2) with the IO-Link master unit in analog current output mode. Otherwise, the unit might fail.
