Abstract
Abstract A rapid fluid analyzer for determining the percentage of a first fluid in a fluid mixture. A portion of the first fluid which is supplied to a mixing chamber is bled to a first chamber. The first fluid is also blended with a second fluid in the mixing chamber to form a fluid mixture. This fluid mixture is communicated to a storage chamber. A portion of the fluid mixture is bled to a second chamber. An identical energy wave is dispatched through the first fluid and the fluid mixture. A first receiver in the first chamber accepts the energy wave that passes through the first fluid. A second receiver in the second chamber accepts the energy wave that passes through the fluid mixture. The first receiver communicates a reference signal indicative of the accepted energy wave in the first fluid to an electronic detector. The second receiver likewise communicates a corresponding signal indicative of the accepted energy wave in the fluid mixture to the electronic detector. The electronic detector compares the corresponding signal with the reference signal to determine if a phase differential exists therebetween. The phase differential which is directly proportional to the percentage of the first fluid in the fluid mixture will permit instant monitoring by the analyzer.

A fluid analyzer means for continually monitoring the percentage of a first fluid in a flowing fluid mixture, said analyzer means comprising: a housing having a first chamber and a second chamber therein, said first chamber having a first inlet port in communication with said first fluid and a first outlet port in communication with the atmosphere to permit the first fluid to freely flow thereto upon passing through a first jewel control in the first inlet port, said first jewel regulating the flow of the first fluid into the first chamber, said second chamber having a second inlet port in communication with a chamber where said first fluid and a second fluid are combined into a fluid mixture and a second outlet port in communication with the atmosphere to permit the fluid mixture to freely flow thereto upon passing through a second jewel control in the second inlet port, said second jewel regulating the flow of the fluid mixture into the second chamber; signal sending means located in said first and second chambers for transferring an identical sound wave through said first fluid and said fluid mixture, said sending means having a first bimorph transmitting transducer located in the first chamber for dispatching sound waves through said first fluid, said sending means having a second bimorph transmitting transducer located in the second chamber for dispatching said sound waves through said fluid mixture, said first and second bimorph transmitting transducers being simultaneously driven by a sinusoidal electrical signal from an electronic oscillator to produce said identical sound waves; a first bimorph receiving transducer located in said first chamber a first predetermined distance from said first bimorph transmitting transducer for accepting said dispatched sound waves passing through said first fluid, said first bimorph receiving transducer converting said sound waves into a reference signal indicative of the first fluid; a second bimorph receiving transducer located in said second chamber a predetermined distance from said second bimorph transmitting transducer for accepting said dispatched sound waves passing through said fluid mixture, said second bimorph receiving transducer converting said sound wave into a test signal indicative of the fluid mixture; electronic detector means connected to said first bimorph receiving transducer, said second bimorph receiving transducer, and said electronic oscillator for comparing a phase differential between said reference signal and the test signal in relation to the sinusoidal electrical signal, said phase differential being directly proportional to the percentage of said first fluid in the mixture; and indicator means responsive to said phase differential to give a visual indication of the percentage of said first fluid in the mixture.
