1. Even instantaneous pressure fluctuation such as water hammer must be within the permissible pressure.
2. Flow monitoring performance is defined by the values measured under the following conditions using OMRON's factory adjustment equipment.
• OMRON's factory adjustment equipment: Pipe diameter 20A, straight pipe length 900 mm or more, recommended pipe joint (KITZ's PTZ-20A), dedicated adapter (E8FC-YA-R20A)
• The long side of the chassis holding unit is installed toward the upstream side of the piping. Refer to Piping method on Catalog.
• Measured normal temperature water (approx. 23°C) under normal temperature environment (approx. 23°C) Since each performance depends on the water level of the piping, there is a possibility that the measured value may deviate depending on the condition that the inside of the piping including the pipe joint is not filled with water, fluid pulsation, and clogging of the piping.
3. Cutting to zero is the function outputting the flow rate less than the minimum rated flow rate as zero.
4. The accuracy of flow rate monitoring when the pipe diameter is 20A. For piping sizes 10A, 15A and 25A, refer to Characteristic Data on Catalog in the catalog before use.
5. The ambient temperature characteristics are defined by the values measured under the following conditions.
• Pipe diameter 20A, Straight pipe length: 900 mm or more, recommended pipe joint (KITZ's PTZ-20A), dedicated adapter (E8FC-YA-R20A)
• The long side of the chassis holding unit is installed toward the upstream side of the piping. Refer to Piping method on Catalog.
• Water at room temperature (approx. 23°C) was measured at a flow rate of 30 l/min.
6. The performance of temperature monitoring is specified by the values measured under the following conditions.
• Pipe diameter 20 A, recommended pipe joint (KITZ's PTZ-20A), dedicated adapter (E8FC-YA-R20A)
• The long side of the chassis holding unit is installed toward the upstream side of the piping. Refer to Piping method on Catalog.
• In a normal temperature environment (approx. 23°C)
7. If the pipe temperature exceeds 70°C, do not contact any cables with the pipe.
8. Do not connect outputs CH1 (pin 4) or/and CH2 (pin 2) with the IO-Link master unit in analog current output mode. Otherwise the IO-Link master might fail.
