Any unit is fine — m³/h, Nm³/h, ACFM, kg/h. Please note whether flow is at normal or actual operating conditions.
Gauge or absolute both fine — just include the suffix (barg / bara / psig / kPa).
Process fluid or vapor — e.g. sulfuric acid mist, steam, natural gas, sea water.
AISI, EN/DIN or any standard — or write "not sure" and we will recommend based on your medium.
