IFM SM9000 SMR21XGXFRKG/US Magnetic-inductive Flow Meter

Product overview

The ifm SM9000 (SMR21XGXFRKG/US) is a magnetic-inductive flow meter for conductive liquids, water and water-based media. It measures flow over 5…300 l/min (0.3…18 m³/h), with an accuracy of ± (0.8 % of the measured value + 0.5 % of the final value of the measuring range) and a repeatability of ± 0.2 % of the final value of the measuring range, and also measures medium temperature over -20…80 °C. ifm specifies a medium conductivity of at least 20 µS/cm and a viscosity below 70 mm²/s at 40 °C. ifm recommends an inlet run of 3 x DN and an outlet run of 1 x DN. The process connection is a G 2 external thread (DN50) with flat seal, the pressure rating is 16 bar, the wetted parts are a stainless steel (1.4404 / 316L) pipe section, fiber-reinforced NBR process connection gasket, FKM, stainless steel (1.4571 / 316Ti) and PEEK and the medium temperature range is -10…90 °C. It provides 2 switching outputs (PNP/NPN), 1 analog output (4…20 mA or 0…10 V), frequency and pulse outputs and IO-Link, with the switching outputs configurable as normally open or normally closed and rated at 250 mA each, runs on 18…32 V DC and connects through an M12 connector (A-coded, 4 gold-plated contacts). The unit measures 200 x 103 x 117 mm and is rated IP65 and IP67 for -10…60 °C ambient. It has UL approval under file E174189.
