title: Note: pneumatically modulated liquid delivery with feedback control.
abstract: We present the design and characterization of a pneumatically driven liquid delivery system using an embedded microcontroller with feedback control capable of maintaining a stable, constant flow rate over several hours of operation. Flow rates with relative standard deviations less than 1% were achieved and compared to a typical laboratory syringe pump.
