FlowControl-Sub is a microprocessor-controlled fully submersible 3-way valve system for use in flow-through applications on profiling platforms such as for example CTD’s or profiling floats.
During profiling, the system diverts ambient water through a cartridge filter on either the up- or downcast. When the bottom of the profile has been reached, the system switches so that non-filtered water is measured. The profiles of filtered and unfiltered measurements allow for high-accuracy differential measurements of particle properties, for example absorption, in the entire profile.
