4.0 PIPING SM425 INSTRUCTION MANUAL
Supply air pressure (flow) may vary depending on the process pressure. It is recommended using a flow
gauge and an air-set (pressure regulator) that is suitable for the process pressure.
- When using the ZA8F Flow Setting Unit and SM425CAL Automatic Calibration Unit, note the supplying
airflow (pressure) will vary depending on the process pressure.
