Flow Determination by Chemical Method
standard by Technical Association of the Pulp and Paper Industry, 01/01/2004
Full Description
In many instances, it is inconvenient to install a weir or other flow measuring device to determine the flow of white water or thin stock. In such a case the flow may be found by introducing a known solution of a salt, such as sodium thiosulfate, into the stream. By determining the dilution of the salt in the unknown stream, the flow may be calculated with reasonable accuracy.
