METHODS, SYSTEMS, AND APPARATUS PROVIDING A TEMPERATURE- CONTROLLED PROCESS LIQUID

摘要

Disclosed are systems and apparatus adapted to control a temperature of a process liquid in a metering line of an instrument. In one aspect, a temperature-controlled liquid delivery apparatus has a pre-flux member operable to control a first temperature set point SP1 of the process liquid in a flow path between a feed tank and a metering apparatus, a metering line connecting the metering apparatus and a probe, and a line flux member directly thermally coupled to the metering line and operable to control a second temperature set point SP2 of the process liquid contained in the metering line. Methods of operating the system are provided, as are other aspects.
