How to Connect Your HPLC Flow Meter to a PC

Accurate HPLC flow rate records not only indicate GMP but are crucial when the FDA comes to call. Digital liquid flow meters such as the FlowCal 5000 support FDA compliance for IQ, QQ and PQ validations in calibrating HPLC pump flow rates.  Connecting these meters to a PC with an RS-232 interface transfers flow meter readings into Excel via the Windows HyperTerminal program.  It is a three-step process whereby data are collected and displayed using HyperTerminl.exe, copied on a clipboard and pasted into Excel for analysis.

Before starting on this project be sure the flow meter is off, otherwise you risk damage to the RS-232 and/or the PC or printer.  Then follow these steps:… Read the rest
