EGE expands its range of inline flow controllers by two models featuring robust process connections. Both types are resistant to aggressive media. The SDN 503 model detects flows between 1 and 200 ml/min and withstands pressures up to 10 bar. The SDN 504 DYN model is suitable for micro flow pulses from 0.02 ml/min onwards and pressures up to 20 bar. Measured values are continuously monitored by internal electronics which also generate a switching signal should the flow pulses discontinue. The dwell time can be adjusted in a 0.5…10 s range. Moreover, an integrated LED display shows the current flow status. Both units are fitted into pipes via a tube fitting or a G¼ thread. Due to their compact design, the sensors require little space.
