Controlling the Mixing Ratio of Two Fluids
Transmitting and alarming the input flow rate ratio of two fluids
(gas or liquid) allows these to be mixed in a predetermined
ratio in continuous processes. The sensing element is
normally a turbine flow meter, which outputs pulses at a
frequency proportional to flow rate. The A/B ratio can also be
transmitted for totalized rate (or delivered volume).
