BACKGROUND
In high pressure boilers, it is necessary to monitor the return condensate before it goes back to the boiler to ensure that it is not contaminated beyond acceptable limits. In smaller boilers, the return condensate can have a fairly high dissolved solids concentration, which can be measured with a standard conductivity meter. In the case of large boilers, such as those used to generate electricity, the allowable level of solids is in the low parts-per-million range. The conductivity caused by the dissolved solids is often masked by the larger conductivities of water treatment chemicals that have been added to protect the boiler. In a case like this, the Larson Lane Condensate Monitor Model CH16D is used to separate the conductivity caused by the dissolved solids from the conductivity caused by the water treatment chemicals.
