Continuous flow ratio monitor

A system of the class described comprising a housing having an elongated mixing compartment having an inlet for a solvent under pressure, and an outlet for a solution:

• means for conducting solute to said compartment, including a conduit defining at least in part a flow passageway of ascertainable depth between opposing windows;
• means including flow of solvent under pressure into said compartment inducing flow of solute through said conduit between said opposing windows and into said mixing compartment;
• means in said compartment for mixing the solute and solvent in pressure differential flow induced proportions, to form a solution under positive pressure at said outlet;
• and
• conduit means connected to said outlet for discharging said solution defining at least in part a flow passage of ascertained depth between opposing windows closely disposed to the other opposing windows for comparison of energy transmissivities of the solute at said depths related to their proportion in said solution.

A solution dispensing system comprising:

• means for supplying the solvent under pressure in a confined flowing stream;
• means for supplying solute under pressure in a confined flowing stream;
• means for progressively mixing said streams in a proportioned ratio to dispense a stream of flowing solution;
• means for monitoring said proportioned ratio including closely disposed chambers for viewing the light transmissivity of said streams of solute and solution flowing at relative depths indicative of a desired percentage of solute in the solution;
• means for correcting relative rates of flow of said solvent and solute for a null point traverse in said comparison;
• and
• means for introducing to said solute a tracer including a source and a flow control valve for varying the flow rate of the tracer to optimize the optical level of the null point traverse.

A solution sprayer comprising:

• means for supplying water flowing under pressure;
• flow control means aspirating a solute usually flowing under negative gauge pressure and mixing it with said water flowing under positive pressure;
• means for supplying and controlling the flow of a tracer to said solute to optimize the null point comparison of the energy transmissivity of the solute and the solution with respect to their tracer content at different relative depths of flow;
• and
• means for comparing the energy transmissivity of the solute and solution for a null point comparison including scale means indicating relative depths of flow of solute and solution.

A monitoring device comprising adjacent chambers each having inlet and outlet connections for conducting flowing fluids separately through them, said chambers having:

• translucent target windows at adjacent ends of said chambers transmitting uniform illumination and transparent windows at the viewing ends of said chambers opposite thereto defining adjacent viewing areas for optical comparison;
• said transparent windows being spaced different distances from their respective target windows;
• means for locating one of the transparent windows a predetermined distance from its target window to provide an ascertained ratio of the relative different distances;
• means for supplying one of the chambers with a flowing stream of a visually distinctive solute;
• and
• means for supplying the other chamber with a flowing stream of a solution containing a controlled ratio of said solute.

In a device of the class described a housing having three separate compartments two of which have light transmitting windows at opposite ends one of which is adjustably mounted, and each of the two compartments having an inlet and an outlet for conducting flowing fluids between their respective windows,

• the third compartment having a partition with a valve port therethrough and defining above it a tracer reservoir with an outlet at its top, an inlet opening above it, the partition and a valve outlet chamber below it having an outlet opening in communication with one of said two compartments,
• differential pressure responsive valve means in said outlet chambers normally closing said valve port,
• piston means above said inlet opening subject to the pressure above the valve means, and
• valve means interconnecting said top outlet and said outlet opening.
