Electronic Flow Controllers
By DE staff
Fluid Power Machine BuildingClippard Cordis offers precise linear flow control within a closed-loop system with high resolution and repeatability.
Clippard introduced its Cordis flow controller, which uses a fast-reacting mems technology sensor upstream from a proportional valve. The controller is capable of a 50:1 turndown ratio, 50 ms response time and ≤25 mV resolution. It also offers the option of a DR-2 regulator for accurate and precise pressure control. Unlike other mass flow controllers that require a 30-minute warm-up time, large differential pressures, and limited flow ranges, Clippard says the Cordis requires less than one minute warm-up, its pressure drop is ≤14″ H2O, and its flow ranges from 0 to 30 sccm. Standard control options include 0.2 to 10 VDC, 4.32 to 20 mA, and 3.3 VDC serial.
