Class Information
Number: 137/89
Name: Fluid handling > Self-proportioning or correlating systems > Mixture condition maintaining or sensing > Dividing and recombining flow
Description: Systems in which a fluid flow is divided into a plurality of flow paths which are subsequently recombined, the ratio of the flows thus divided and recombined being controlled in response to a means sensing a condition to be maintained.
