An automated sample conditioning system for conditioning and preparing steam and hot water samples at a constant flow rate and velocity continuously monitors and adjusts flow rate in the sample line. Sample flow is metered through a flow rate device such as an orifice plate of known flow characteristics, and a downstream pressure value is provided by either a fixed back pressure regulator/relief valve or by a pipe section of known length and diameter. A pressure transducer continuously monitors pressure in the sample line upstream from the orifice plate. A control analyzer automatically adjusts a motorized pressure reducing device in response to fluctuations in pressure monitored by the pressure transducer in order to maintain constant flow rate and velocity. Monitoring devices and displays acquire, display and control critical pressure, temperature and flow rate parameters throughout the system. Network communications capability for remote, unattended monitoring control and data acquisition is also provided.
