Technical Specifications *¹ Dry and clean gas without dirt and oil *І Flow transfers into value below. Standard volume std (pre-setting): 20 ° C, AP 101.3 kPa * 3 Please ensure both sides are connected to pipe when operating. If one side is not connected, pressure will decrease and lead to inaccurate measurement 44 Input Power Voltage range 24 V ± 10 % non-isolation DC Power consumption 24 V: - Voltage output and RS-485 models: max. 0.96 W - Current output model: max. 1.2 W Gas Flow Measurement Measurement range*² 2 ~ 200 L / min*¹ Measurable gas Air, N, Ar, CO (varies in different models) 2 2 Operation pressure 0 ~ 0.75 MPa Max. durable pressure 1 MPa Pressure-related inaccuracy ± 5 % F.S.
(0 ~ 0.75 MPa) entire process The process is based on pressure 0.35 MPa. Pressure can also lead to innaccuracies other than measurement inaccuracy.*3 Measurement accuracy ± 3 % F.S. entire process Temperature-related inaccuracy ± 5 % F.S. (0° C ~ 50°C) entire process The process is based on temperature 25 °C. Temperature can also lead to innaccuracies other than measurement inaccuracy Functions Peak volume display / accumulated volume display / reverse display / zero adjustment / button lockup / energy-saving mode / percentage (analog output) / delay decision Display Flow volume display Max.
