When the actual gas volume flow meter to measure how much rotor should first flow units (eg SCFM, LPM, etc.) into the actual condition of the unit rotor flow meter parameter, then determine the flow meter diameter, can be used as follows The actual formula actual volume and standard volume unit conversion. ACFM = SCFM × 14.7 / Pa × Ta / 530ACFM: actual operating conditions of gas flow rate ft3 / minSCFM: gas flow under standard conditions ft3 / minPa: operating pressure (PSIA) = PSIG + 14.7Ta: Kim temperature (R) = F +460 normal operating conditions Ambient temperature: -25 ° ~ + 60 ℃; Relative humidity: 5% to 90%; Power supply: single-phase AC power supply 85 ~ 250V, 45 ~ 63HZ; DC power supply 16VDC ~ 36VDC; Power Dissipation: less than 20W.
