This Technical Information Paper outlines a method for measuring the average rate of steam condensation of the drying cylinders that discharge into a separator tank. The tank must be equipped with shut-off valves and a sight glass or magnetic level indicator for observing the level of condensate in the tank.

To accurately measure the dryer section condensing rate with a vertical separator, it is necessary that all connections to the separator and all joints in piping and components be completely tight so that no condensate leakage occurs. To accurately time the condensate rise, hand valve(s) must be easily turned and provide tight shut-off and sight glass indicators must be clean so condensate level can be easily seen.
