Features Lower cost but high accuracy measurement. High speed response and zero stability. 0-5VDC or 4-20mA input/output signal and +/-15VDC or 24VDC power supply. Mediocrity D-sub 9pin. Gases registered in EX-250S are usable by rotary-switch. *Calculate the flow rate with conversion factor based on N2 gas. RoHS compliance, CE marked. Stand Specifications (*1) The gases must be dry and clean, free of corrosive components and foreign matter such as dust and mist. - (*2) The flow rate calibration units SCCM and SLM indicate a mass flow rate converted to a volume flow rate in cc/min and L/min at 0°C and 1 atm. (*3) Accuracy for calibration gas: N2, flow range (max. full scale). - - (*4) The operating differential pressure may differ depending on specifications. - - (*5) Mass flow meter does not contain magnetic stainless steel. - - (*6) Contact us for any other joints. - - - (*7) Exclusive of weight of joint. - - - (*8) Pressure condition would be needed when you order.
